Stent pour implantation percutanée d'une valve cardiaque

Abstract : The goal of this work is to develop an atraumatic stent concept for percutaneous aortic valve replacement. Shape setted braided nitinol wires, thanks to their specific geometry and elasticity, allows stent's compressibility, self deployment and aortic root preservation. Prototypes manufacturing technique and relatives constraints are presented. Performance of the obtained prototypes are evaluated in vitro, in terms of sealing, static and dynamic regurgitation. More specifically, the pulsatile bench testing has been optimized to take in account the compliant constraint of the aortic valve environment. The results bring to the fore which are the dimensions (head height, cone angle...) and the structures features that do influence the endoprosthesis behavior significantly.
