Title (EN) MINIMALLY-INVASIVE HEART VALVES AND METHODS OF USE
(FR) VALVULES CARDIAQUES MINIMALEMENT INVASIVES ET METHODES D'UTILISATION CORRESPONDANTES
Abstract:
(EN) Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. In a first embodiment, an expandable pre-assembled heart valve includes a plastically-expandable annular base having plurality of upstanding commissure posts. A tubular flexible member including a prosthetic section and a fabric section is provided, with the prosthetic section being connected to the commissure posts and defining leaflets therebetween, and the fabric section being attached to the annular base. In a second embodiment, an expandable heart valve includes an annular tissue-engaging base and a subassembly having an elastic wireform and a plurality of leaflets connected thereto. The annular base and subassembly are separately stored and connected just prior to delivery to the host annulus. Preferably, the leaflet subassembly is stored in its relaxed configuration to avoid deformation of the leaflets. The expandable heart valves may be implanted using a balloon catheter. Preferably, the leaflets of the heart valves are secured to the commissure regions of the expandable stents using a clamping arrangement to reduce stress.
(FR) L'invention concerne des valvules cardiaques expansibles destinées à être utilisées dans le cadre d'interventions chirurgicales de remplacement de valvules minimalement invasives. Dans un premier mode de réalisation, on utilise une valvule cardiaque expansible pré-assemblée se présentant sous la forme d'une base annulaire en plastique expansible pourvue d'une pluralité de tiges de commissure verticales. On utilise également un élément tubulaire flexible comprenant une section prothèse et une section tissu, la section prothèse étant reliée aux montants de commissure et définissant des valves entre celles-ci, la section tissu étant fixée à la base annulaire. Dans un second mode de réalisation, on utilise une valvule cardiaque expansible constituée d'une base annulaire de contact avec les tissus et d'un sous-ensemble se présentant sous la forme d'un fil élastique auquel sont reliées plusieurs valves. La base annulaire et le sous-ensemble sont stockés séparément et assemblés juste avant leur introduction dans l'anneau hôte. De préférence, le sous-ensemble de valves est stocké dans sa configuration relâchée de manière à éviter la déformation desdites valves. Les valvules cardiaques expansibles peuvent être implantées à l'aide d'un cathéter à ballonnet. De préférence, les valves des valvules cardiaques sont fixées aux zones de commissure des endoprothèses expansibles au moyen d'un dispositif de serrage, de manière à réduire toute tension.
