Title (EN) TRANSAPICAL DELIVERY MIRTAL VALVE PROCEDURE DEVICES
(FR) DISPOSITIFS D’INTERVENTION POUR VALVE MITRALE D'ADMINISTRATION TRANSAPICALE
Abstract:
(EN) Various embodiments of a device for mitral valve repair are described. In one example, the device can be used to place a pair of magnets between the flaps of the mitral valve. The magnets hold the flaps together near its center, with a result similar to that achieved through the Alfieri stitch. To place the magnets, the device is inserted through the apex of the heart in a transapical procedure and extended up into the left ventricle toward the mitral valve. When in position with the mitral valve, a pair of grasper fingers of the device are used to place the pair of magnets over the flaps, and the magnets are released. Once released, magnetic attraction between the magnets holds the flaps together. In other embodiments, the device can be used to place staples or sutures or other bonding elements over the flaps of the mitral valve.
(FR) L’invention concerne, selon divers modes de réalisation, un dispositif de réparation de valve mitrale. Selon un exemple, le dispositif peut être utilisé pour placer une paire d'aimants entre les rabats de la valve mitrale. Les aimants maintiennent les rabats ensemble à proximité de son centre, en présentant un résultat similaire à celui obtenu par l'intermédiaire de la technique du bord à bord d'Alfieri. Afin de placer les aimants, le dispositif est inséré par le sommet du cœur par une technique transapicale et s'étend jusque dans le ventricule gauche vers la valve mitrale. Lorsqu'ils sont en position avec la valve mitrale, une paire de doigts de préhension du dispositif sont utilisés pour placer la paire d'aimants sur les rabats, et les aimants sont libérés. Une fois libérés, l'attraction magnétique entre les aimants maintient les rabats ensemble. Selon d'autres modes de réalisation, le dispositif peut être utilisé pour placer des agrafes ou des sutures ou d'autres éléments de liaison sur les rabats de la valve mitrale.
