Commitments and Contingencies	8. Commitments and Contingencies On April 14, 2017, representatives for the estate of an individual plaintiff filed a wrongful death complaint with the Suffolk Superior Court, in the County of Suffolk, Massachusetts, against the Company and other defendants, including Harvard Bioscience, Inc., or HBIO, the former parent of the Company that spun off the Company in 2013, as well as another third party. The complaint sought payment for an unspecified amount of damages and alleged that the plaintiff sustained terminal injuries allegedly caused by products provided by certain of the named defendants and utilized in connection with surgeries performed by third parties in Europe in 2012 and 2013. This lawsuit related to the Company’s first-generation trachea scaffold technology for which the Company discontinued development in 2014, and not to the Company’s current HRGN Esophageal Implant. On April 27, 2022, the Company and HBIO executed a settlement with the plaintiffs (the “Settlement”), which resolves all claims relating to the litigation. The Settlement resulted in the dismissal with prejudice of the wrongful death claim, and neither the Company nor HBIO admit any fault or liability in connection with the claim. The Settlement also resolved any and all claims by and between the parties and the Company’s product liability insurance carriers, which resulted in the dismissal with prejudice of all claims asserted by or against those carriers, the Company and HBIO. In relation to the litigation, the Company paid approximately $5.9 million of aggregate costs related to the lawsuit, of which 100% has been paid as of December 31, 2022. This aggregate amount included the cost of legal and related costs incurred by the Company, which consisted of attorneys’ fees and advisor and specialist costs as part of its defense in this matter. On March 3, 2022, the Company received a cash payment of approximately $0.1 million from Medmarc, the Company’s insurance carrier. This amount represented a reimbursement of previously incurred legal costs and was recorded as a reduction to selling, general and administrative expenses during the six months ended June 30, 2022. With respect to such $5.9 million of costs described above, the Company was required to either pay such costs directly or indemnify HBIO as to such amounts it incurs. Of such amounts, the Company anticipated that HBIO would pay an aggregate amount of $4.0 million by the end of the second quarter of 2022. With respect to the indemnification obligation of the Company to HBIO pertaining to such costs, the Company and HBIO entered into a Preferred Issuance Agreement dated as of April 27, 2022, or the “PIA”. In connection with the PIA, the Company and HBIO agreed that once HBIO had paid at least $4.0 million in such costs, to satisfy the Company’s indemnification obligations with respect thereto, in lieu of paying cash, the Company would issue senior 8% convertible preferred stock to HBIO that will contain terms as described in the PIA, including the term sheet attached thereto. On June 10, 2022, following the execution of a subscription agreement and HBIO providing evidence of payment of the requisite $4.0 million amount, the Company issued HBIO 4,000 shares of Series E 8% Convertible Preferred Stock at a price of $1,000 per share to satisfy the Company’s related indemnification obligations aggregating $4.0 million, which included the accrual for contingency of $3.3 million and approximately $0.8 million of legal and related costs paid on behalf of the Company by HBIO previously included in accrued expenses. From time to time, the Company may be involved in various claims and legal proceedings arising in the ordinary course of business. Other than the above matter, there are no such matters pending that the Company expects to be material in relation to its business, financial condition, results of operations, or cash flows.
