The Company has a directors and officers&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019; liability insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid resulting from the indemnification of its officers and directors.

AeroForm embodies inventions that have been patented in certain key jurisdictions. Certain of those patents are held by Shalon Ventures (either alone or jointly with AirXpanders). Shalon Ventures and AirXpanders have entered into a License Agreement dated &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 9, 2005 (&lt;/div&gt;as amended on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 9, 2009 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 9, 2012) &lt;/div&gt;in relation to those inventions (Shalon Ventures License Agreement). Pursuant to the Shalon Ventures License Agreement, Shalon Ventures granted AirXpanders an exclusive license to develop, make, have made, use, offer for sale, sell, have sold, import and export products that, but for the license, would infringe &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; or more claims of the patents. The license covers all human uses of self-expanding tissue expanders anywhere in the world and includes the right to sublicense.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;In consideration for the license, AirXpanders pays Shalon Ventures a running royalty of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;3%&lt;/div&gt; of net sales of the licensed invention. If the amount of royalties paid in a calendar year is less than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$10,000,&lt;/div&gt; then AirXpanders shall also pay Shalon Ventures&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019; out of pocket costs for prosecuting and maintaining the relevant patents. Each party indemnifies the other for any liability arising out of its material breach of the license, or its gross negligence, intentional misconduct and illegal actions. AirXpanders also indemnifies Shalon Ventures for any liability arising out of the commercialization of products using the license. For the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018&lt;/div&gt;&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; respectively, the Company recorded approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$35,000&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$5,000&lt;/div&gt; in royalty fees, which is included in cost of goods sold in the accompanying condensed consolidated statements of operations.

These events of default include, among other things, the failure to pay amounts due under the credit facilities, insolvency, the occurrence of a material adverse event, which includes a material adverse change in our business, operations or properties (financial or otherwise) or a material impairment of the prospect of repayment of any portion of the obligations.&amp;nbsp;A violation of any of these covenants&amp;nbsp;or the occurrence of a material adverse change&amp;nbsp;could result in a default under the loan and security, which would result in termination of all commitments and loans under the agreement and all amounts owing under the agreement to become immediately due and payable. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018, &lt;/div&gt;the Company was in violation of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; of these covenants. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 9, 2018, &lt;/div&gt;the Company and the financial institution entered into the waiver and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; amendment to the loan and security agreement, pursuant to which it received a waiver of the event of default for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018 &lt;/div&gt;noncompliance with a financial covenant,&amp;nbsp;and modified certain financial&amp;nbsp;covenants.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;In connection with the loan and security agreement, the Company issued warrants to the financial institution&amp;nbsp;for the purchase of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;277,778&lt;/div&gt;&amp;nbsp;shares of its Common Stock with an exercise price of&amp;nbsp;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.62&lt;/div&gt; per share.&amp;nbsp;&lt;div style="display: inline; font-family:Times New Roman, Times, serif; font-size:10pt"&gt;The fair value of the warrants of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$227,000&lt;/div&gt; on the date of issuance was recorded as additional&amp;nbsp;debt discount.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company recorded &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$40,000&lt;/div&gt; to interest expense related to amortization of the debt discount and issuance costs for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt;&amp;nbsp;months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018&lt;/div&gt;&lt;div style="display: inline; font-family:Times New Roman, Times, serif; font-size:10pt"&gt;.

The provisions of ASC&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;820&lt;/div&gt;&lt;/div&gt;&amp;nbsp; apply to all financial assets and liabilities measured at fair value.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;As defined in ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;820,&lt;/div&gt; fair value represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, ASC &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;820&lt;/div&gt; defines a &lt;div style="display: inline;

Under this method, deferred income tax assets and liabilities are recorded based on the estimated future tax effects of differences between the financial statement and income tax basis of assets and liabilities. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating loss and tax credit carryovers. Deferred tax assets and liabilities are measured using the enacted tax rates applied to taxable income. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided against the Company&lt;div style="display: inline; font-family:'Times New Roman', Times, serif;font-size:10pt;"&gt;&amp;#x2019;s deferred income tax assets when it is more likely than&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt;&lt;/div&gt;&amp;nbsp; that the asset will&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt;&lt;/div&gt;&amp;nbsp; be realized.&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considers all available evidence, including past operating results, estimates of future taxable income and the feasibility of tax planning strategies. In the event that the Company changes its determination as to the amount of deferred tax assets that are more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; to be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" margin: 0pt; text-align: left; font-family: Times New Roman, Times, serif; font-size: 10pt;"&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company follows authoritative guidance regarding uncertain tax positions. This guidance requires that realization of an uncertain income tax position must be more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; (i.e. greater than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50%&lt;/div&gt; likelihood of receiving a benefit) before it can be recognized in the financial statements. The guidance further prescribes the benefit to be realized assumes a review by tax authorities having all relevant information and applying current conventions. The interpretation also clarifies the financial statement classification of tax related penalties and interest and sets forth disclosures regarding unrecognized tax benefits. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

The fair value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. The expense recognized for the portion of the award that is expected to vest has been reduced by an estimated forfeiture rate. The forfeiture rate is determined at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company uses the Black-Scholes option-pricing model (the "Black-Scholes model") as the method for determining the estimated fair value of stock options.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Term &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company's expected term represents the period that the Company's stock-based awards are expected to be outstanding and is determined using the simplified method, which essentially equates to a weighted average of the vesting periods and total term of the award.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Volatility&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;Expected volatility is estimated using comparable public company&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019;s volatility for similar terms as the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a long enough operating period as a public company to estimate its own volatility. Over time as the Company develops its own volatility history it will begin to incorporate that history into its expected volatility estimates. &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Dividend&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Black-Scholes model calls for a single expected dividend yield as an input.

font-style: normal;"&gt;four&lt;/div&gt;&lt;/div&gt;&amp;nbsp; criteria are met: delivery has occurred, there is persuasive evidence of an arrangement, the fee is fixed or determinable, and collectability of the related receivable is reasonably assured.&amp;nbsp;The Company recognizes revenue when title to the product and risk of loss transfer to customers, provided there are&lt;div style="display: inline;

Actual sales returns in any future period are inherently uncertain and thus&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may&lt;/div&gt;&lt;/div&gt;&amp;nbsp; differ from the estimates. If actual sales returns differ significantly from the estimates, an adjustment to revenue in the current or subsequent period would be recorded.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.5pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;The Company has established an allowance for sales returns of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.2&lt;/div&gt;&lt;div style="display: inline; font-family:'Times New Roman', Times, serif;font-size:10pt;"&gt;&amp;nbsp;million as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018, &lt;/div&gt;recorded net against accounts receivable in the balance sheet. &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; amount was recorded as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2017, &lt;/div&gt;as all a majority of&amp;nbsp;sales were recorded in Australia.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.5pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Shipping and Handling Costs&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.5pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;Shipping and handling costs are included as a component of cost of goods sold.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Accounts Receivable and Allowance for Doubtful Accounts&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.1pt;"&gt;Accounts receivable are stated at cost, net of allowance for doubtful accounts. Credit is extended to customers based on an evaluation of their financial condition and other factors. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; charge interest on past due balances. The Company generally does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains an allowance for doubtful accounts.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.1pt;"&gt;The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates that customers &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have an inability to meet their financial obligations and receivable amounts are outstanding for an extended period beyond the invoice terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off. The accounts receivable aging is reviewed on a regular basis and write-offs are recorded on a case-by-case basis net of any amounts that &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be collected. Allowance charges are recorded as operating expenses. Based on the Company&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019;s customer analysis, it did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have an allowance for doubtful accounts at &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018&lt;/div&gt;&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2017.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Revenue and Receivables Concentration&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt 7.5pt;text-align:left;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt 0pt -2pt; text-align: left; text-indent: 27pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; customer accounts for more than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10%&lt;/div&gt; of net revenues for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; respectively,&lt;div style="display: inline; font-family:'Times New Roman', Times, serif;font-size:10pt;"&gt;&amp;nbsp;or of the accounts receivable balance&amp;nbsp;as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 31, 2017.&amp;nbsp;&lt;/div&gt;U.S. product sales are to hospitals and accounted for&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;89%&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;40%&lt;/div&gt;&amp;nbsp;of total net revenues for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; March 31, 2018 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; respectively, with the remainder to hospitals in Australia.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" margin: 0pt; text-align: left; font-family: Times New Roman, Times, serif; font-size: 10pt;"&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Stock-Based Compensation&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt; text-align: left; text-indent: 23pt; font-family: Times New Roman,Times,serif; font-size: 10pt;"&gt;Stock-based compensation is measured at the grant date based on the fair value of the award. The fair value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. The expense recognized for the portion of the award that is expected to vest has been reduced by an estimated forfeiture rate. The forfeiture rate is determined at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company uses the Black-Scholes option-pricing model (the "Black-Scholes model") as the method for determining the estimated fair value of stock options.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Term &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company's expected term represents the period that the Company's stock-based awards are expected to be outstanding and is determined using the simplified method, which essentially equates to a weighted average of the vesting periods and total term of the award.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Volatility&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;Expected volatility is estimated using comparable public company&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019;s volatility for similar terms as the Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a long enough operating period as a public company to estimate its own volatility. Over time as the Company develops its own volatility history it will begin to incorporate that history into its expected volatility estimates. &lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Expected Dividend&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Black-Scholes model calls for a single expected dividend yield as an input. The Company has never paid dividends and has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; current plans to pay dividends on its common stock.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;&lt;div style="display: inline; font-style: italic;"&gt;Risk-Free Interest Rate&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The risk-free interest rate used in the Black-Scholes model is based on the U.S. Treasury &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;zero&lt;/div&gt; coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company recognizes the fair value of stock options granted to nonemployees as stock-based compensation expense over the period in which the related services are received.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt; text-align: left; text-indent: 27pt; font-family: Times New Roman,Times,serif; font-size: 10pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Research and Development&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt; text-align: left; text-indent: 32pt; font-family: Times New Roman,Times,serif; font-size: 10pt;"&gt;Costs incurred in research and development activities (including clinical trials) are expensed as incurred. Research and development costs include, but are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, payroll and personnel expenses, laboratory supplies, consulting costs, travel, parts and materials, equipment expenses, and equipment depreciation.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt; text-align: left; text-indent: 27pt; font-family: Times New Roman,Times,serif; font-size: 10pt;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Income Taxes&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;The Company accounts for income taxes using the asset and liability method. Under this method, deferred income tax assets and liabilities are recorded based on the estimated future tax effects of differences between the financial statement and income tax basis of assets and liabilities. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating loss and tax credit carryovers. Deferred tax assets and liabilities are measured using the enacted tax rates applied to taxable income. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided against the Company&lt;div style="display: inline; font-family:'Times New Roman', Times, serif;font-size:10pt;"&gt;&amp;#x2019;s deferred income tax assets when it is more likely than&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt;&lt;/div&gt;&amp;nbsp; that the asset will&lt;div style="display: inline; font-style: italic;"&gt;&amp;nbsp; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt;&lt;/div&gt;&amp;nbsp; be realized.&lt;/div&gt;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" margin: 0pt 7.5pt; text-align: left; text-indent: 18pt; font-family: &amp;quot;Times New Roman&amp;quot;,Times,serif; font-size: 10pt;"&gt;Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considers all available evidence, including past operating results, estimates of future taxable income and the feasibility of tax planning strategies. In the event that the Company changes its determination as to the amount of deferred tax assets that are more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; to be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style=" margin: 0pt; text-align: left; font-family: Times New Roman, Times, serif; font-size: 10pt;"&gt;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company follows authoritative guidance regarding uncertain tax positions. This guidance requires that realization of an uncertain income tax position must be more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; (i.e. greater than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50%&lt;/div&gt; likelihood of receiving a benefit) before it can be recognized in the financial statements. The guidance further prescribes the benefit to be realized assumes a review by tax authorities having all relevant information and applying current conventions. The interpretation also clarifies the financial statement classification of tax related penalties and interest and sets forth disclosures regarding unrecognized tax benefits. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Segments&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;The Company has determined the chief executive officer is the chief operating decision maker. The Company&lt;div style="display: inline; font-family:Times New Roman, Times, serif;font-size:10pt;"&gt;&amp;#x2019;s chief executive officer reviews financial information presented for purposes of assessing performance and making decisions on how to allocate resources. The Company has determined that it operates in a single reporting segment.&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;"&gt;&lt;div style="display: inline; text-decoration: underline;"&gt;Basic and Diluted Net Loss Per Share&lt;/div&gt;&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, resulting from the conversion or exercise of stock options, stock warrants, convertible debt and convertible preferred stock to the extent dilutive. For the periods presented, all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.05pt;"&gt;Following is a table summarizing the potentially dilutive common shares that were excluded from diluted weighted-average common shares outstanding for the &lt;div style="display: inline;

The Company&amp;#x2019;s ability to achieve profitability is dependent primarily on its ability to gain market share in the U.S, build and maintain manufacturing capacity to support commercial launch in the U.S. and obtain a more profitable per unit manufacturing cost for its products.

The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; charge interest on past due balances. The Company generally does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains an allowance for doubtful accounts.&lt;/div&gt; &lt;div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"&gt;&amp;nbsp;&lt;/div&gt; &lt;div style=" font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:23.1pt;"&gt;The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates that customers &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have an inability to meet their financial obligations and receivable amounts are outstanding for an extended period beyond the invoice terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off.
