A Sutureless Aortic Stent-Graft Based on a Nitinol Scaffold Bonded to a Compliant Nanocomposite Polymer Is Durable for 10 Years in a Simulated In Vitro Model

Abstract

Simulated physiological in vivo hydrodynamic loading has no significant degradative effect on an innovative sutureless stent-graft made from POSS-PCU nanocomposite polymer. Sutureless technology incorporating nitinol stents proved to be robust, with no separation over an accelerated 10-year cycle, which may allow development of durable stent-grafts with better compliance.
