Title (EN) PROSTHETIC VALVES WITH MECHANICALLY COUPLED LEAFLETS
(FR) VALVES PROTHÉTIQUES À LAMES VALVULAIRES MÉCANIQUEMENT ACCOUPLÉES
Abstract:
(EN) Described embodiments are directed toward centrally-opening leaflet prosthetic valve devices having a leaflet frame and a mechanically coupled leaflet. The described leaflet frames have projections that are configured to couple with a leaflet attachment region of a leaflet. Some embodiments include a leaflet retention feature that engages the leaflet frame projections and operates to secure the leaflet to the leaflet frame. Methods of making and using such prosthetic valve devices are also described.
(FR) Selon certains modes de réalisation, l'invention concerne des dispositifs valvulaires prothétiques à lames valvulaires à ouverture centrale comportant une structure de lame valvulaire et une lame valvulaire mécaniquement accouplée. Les structures de lames valvulaires selon l'invention comprennent des saillies qui sont conçues pour s'accoupler à la région de fixation de la lame valvulaire d'une lame valvulaire. Certains modes de réalisation comprennent un élément de retenue de la lame valvulaire qui vient en prise avec les saillies de la structure de la lame valvulaire et sert à fixer la lame valvulaire à la structure de lame valvulaire. L'invention concerne également des procédés de fabrication et d'utilisation de tels dispositifs valvulaires prothétiques.
