Title
(EN) TRANSCATHETER PROSTHETIC HEART VALVE DELIVERY SYSTEM WITH EXPANDABLE STABILITY TUBE
(FR) SYSTÈME DE POSE DE VALVULES CARDIAQUES PROTHÉTIQUES PAR TRANSCATHÉTER, POURVU D'UN TUBE STABILISATEUR EXPANSIBLE
Abstract
(EN) A device for percutaneously delivering a stented prosthetic heart valve. The device includes an inner shaft assembly, a delivery sheath assembly, an outer stability tube, and a handle. The sheath assembly is slidably disposed over the inner shaft, and includes a capsule and a shaft. The capsule compressively contains the prosthesis over the inner shaft. The stability tube is slidably disposed over the delivery sheath, and includes a distal region configured to be radially expandable from a first shape having a first diameter to a second shape having a larger, second diameter. In a first delivery state, the distal region assumes the first shape, providing a low profile appropriate for traversing a patient's vasculature. In a second delivery state, the distal region has the expanded diameter second shape, sized to receive the capsule, such as when retracting the capsule to implant the prosthesis.
(FR) L'invention concerne un dispositif pour la pose par voie percutanée d'une valvule cardiaque prothétique à stent. Le dispositif comprend un ensemble tige interne, un ensemble manchon de pose, un tube stabilisateur externe et une poignée. L'ensemble manchon est disposé coulissant au-dessus de la tige interne et comprend une capsule et une tige. La capsule contient de manière compressive la prothèse sur la tige interne. Le tube stabilisateur est disposé coulissant sur le manchon de pose et comprend une région distale configurée pour être radialement expansible d'une première forme ayant un premier diamètre à une seconde forme ayant un second diamètre, plus grand. Dans un premier état de pose, la région distale prend la première forme, fournissant un profil bas approprié pour traverser la vasculature d'un patient. Dans un second état de pose, la région distale a la seconde forme de diamètre étendu, dimensionnée pour recevoir la capsule, de telle sorte que, lorsque la capsule est rétractée, on peut poser la prothèse.
