Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Endospan Loan Amendment Second Tranche Funding On November 7, 2024 we funded Endospan $10.0 million for the second tranche loan payment pursuant to Endospan's achievement of certain milestones as part of the Endospan Loan Amendment described in Part I, Item 1, Note 3 - “Agreements with Endospan”. We anticipate funding the remaining third tranche loan payment of $8.0 million subject to Endospan’s achievement of milestones related to its pursuit of regulatory approval for the NEXUS products that are specified in the Endospan Loan Amendment. We are in the process of evaluating the impact of the second tranche loan payment on our financial results and operations.
