Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 12. Commitments and Contingencies We received a warning letter from the FDA, dated June 2, 2014, following an inspection of our Miami Lakes, Florida facility conducted in January 2014. The FDA letter cited four categories for us to address: (1) procedures for validating device design, including device labeling; (2) procedures for implementing corrective and preventive action (“CAPA”); (3) maintaining records related to investigations; and (4) validation of computer software used as part of production or quality systems. The warning letter did not require any action by physicians or patients and did not restrict use of our devices. We sent the FDA our initial response to the warning letter within the required fifteen business days of receipt, and committed to undertaking certain quality system improvements and providing the FDA with periodic updates. During 2014 and 2015, we commenced implementing systemic changes and organizational enhancements to address the four warning letter items and related quality systems. We established teams to review and address the items cited by the FDA and engaged external subject matter experts to assist in assessment and remediation efforts. We have developed an overall corporate quality plan and individual quality plans which govern our quality improvement efforts. At March 31, 2015, we had purchase order commitments of approximately $33.6 million related to product costs, supplies, services and property, plant and equipment purchases. Many of our materials and supplies require long lead times. Our purchase order commitments reflect materials that may be received up to one year from the date of order. In addition, we have entered into employment agreements with all of our executive officers. These contracts do not have a fixed term and are constructed on an at-will basis. Some of these contracts provide executives with the right to receive certain additional payments and benefits if their employment is terminated including after a change of control, as defined in these agreements. From time to time we invest in certain development-stage entities in connection with research activities. Certain contingent milestone payments in connection with these arrangements have not been accrued in the accompanying condensed consolidated financial statements as the amounts are indeterminate at this time. The taxation and customs requirements, together with other applicable laws and regulations of certain foreign jurisdictions, can be inherently complex and subject to differing interpretation by local authorities. We are subject to the risk that either we have misinterpreted applicable laws and regulations, or that foreign authorities may take inconsistent, unclear or changing positions on local law, customs practices or rules. In the event that we have misinterpreted any of the above, or that foreign authorities take positions contrary to ours, we may incur liabilities that may differ materially from the amounts accrued in the accompanying condensed consolidated financial statements. *Contingent Consideration and Milestone Payments* In December 2013, we acquired CircuLite using a combination of cash, stock and post-acquisition milestone and royalty payments. The post-acquisition payments are payable based upon the achievement of five specified performance milestones and revenue over periods ranging from 8-10 years subsequent to the acquisition date. The maximum amount of the aggregate post-acquisition payments could be $320 million. As of March 31, 2015, the fair value of the contingent consideration was estimated to be $45.8 million (see Note 4). *License and Development Agreements* From time to time, we license rights to technology or intellectual property from third parties. These licenses may require us to pay upfront payments as well as development or other payments upon successful completion of preclinical, clinical, regulatory or revenue milestones. In addition, these agreements may require us to pay royalties on sales of products arising from the licensed technology or intellectual property. Because the achievement of these milestones is not reasonably estimable, we have not recorded a liability in the accompanying consolidated financial statements for any of these contingencies. *Litigation* From time to time we may be involved in litigation or other contingencies arising in the ordinary course of business. Based on the information presently available, management believes there are no contingencies, claims or actions, pending or threatened, the ultimate resolution of which will have a material adverse effect on our financial position, liquidity or results of operations. In accordance with FASB ASC 450, Contingencies, we accrue loss contingencies including costs of settlement, damages and defense related to litigation to the extent they are probable and reasonably estimable. Otherwise, we expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range.
