Title (EN) LOW PROFILE HEART VALVE AND DELIVERY SYSTEM
(FR) VALVULE CARDIAQUE À PROFIL BAS ET SYSTÈME DE POSE
Abstract:
(EN) Medical devices and methods for endovascularly or transcatheterly replacing a patient's heart valve, including: a delivery system (9) having an entry profile of 30 Fr or less; a self-expandable annulus ring (10) disposed in the delivery system (9) including a self-expandable anchoring and clipping structure and multiple bridges (4) connected to the anchoring and clipping structure; and a replacement heart valve (11) disposed in the delivery system (9) and connected to the bridges (4). The bridges (4) are formed of a shape memory material; during deployment, the bridges (4) fold upwardly inside the self-expandable anchoring and clipping structure to lift the replacement heart valve (11) into position.
(FR) L'invention concerne des dispositifs médicaux et des procédés destinés à remplacer, par voie endovasculaire ou par transcathéter, une valvule cardiaque d'un patient, comprenant : un système de pose (9) comportant un profil d'entrée inférieur ou égal à 30 Fr ; un anneau d'annulus auto-dilatable (10) placé dans le système de pose (9) comprenant une structure d'ancrage et de fixation auto-dilatable et de multiples ponts (4) reliés à la structure d'ancrage et de fixation ; et une valvule cardiaque de remplacement (11) placée dans le système de pose (9) et reliée aux ponts (4). Les ponts (4) sont formés d'un matériau à mémoire de forme ; pendant le déploiement, les ponts (4) se replient vers le haut au sein de la structure d'ancrage et de fixation auto-dilatable en vue de soulever et de positionner la valvule cardiaque de remplacement (11).
