Title
(EN) DEVICE FOR HEART REPAIR
(FR) DISPOSITIF POUR RÉPARATION CARDIAQUE
Abstract
(EN)
A catheter device is described. The device is for implanting a leaflet anchor (10) into the heart as part of a procedure for implanting an artificial chordae line (14). The catheter device comprises: a leaflet anchor (10) for attachment to the leaflet (12) of the heart; and a leaflet anchor deployment mechanism (6), (30), (38) for deploying the leaflet anchor (10). The leaflet anchor deployment mechanism (6), (30), (38) allows for retraction and repositioning of the leaflet anchor (10) after deployment of the anchor (10) into the leaflet (12) via an ejector unit (36) having a grasping device (50) with a first configuration arranged to permit deployment of the leaflet anchor (10) into the leaflet (12) without disengagement of the leaflet anchor (10) from the ejector unit (34), and a second configuration in which the leaflet anchor (10) is reversibly released from the ejector unit (36). In the first configuration the grasping device (50) of the ejector unit (36) grasps a proximal end of the leaflet anchor (10), whilst a distal end of the leaflet anchor (10) is unimpeded by the grasping device (50) to enable it to be implanted in the leaflet (12). In the second configuration the grasping device (50) is disengaged from the leaflet anchor (10).

L'invention concerne un dispositif de cathéter. Le dispositif est destiné à implanter un ancrage de feuillet (10) dans le coeur en tant que partie d'une procédure d'implantation d'une ligne de cordes artificielles (14). Le dispositif de cathéter comprend : un ancrage de feuillet (10) destiné à être fixé au feuillet (12) du coeur ; et un mécanisme de déploiement d'ancrage de feuillet (6), (30), (38) pour déployer l'ancrage de feuillet (10). Le mécanisme de déploiement d'ancrage de feuillet (6), (30), (38) permet la rétraction et le repositionnement de l'ancrage de feuillet (10) après le déploiement de l'ancrage (10) dans le feuillet (12) par l'intermédiaire d'une unité d'éjecteur (36) ayant un dispositif de préhension (50) avec une première configuration agencée pour permettre le déploiement de l'ancrage de feuillet (10) dans le feuillet (12) sans désengagement de l'ancrage de feuillet (10) de l'unité d'éjecteur (34), et une seconde configuration dans laquelle l'ancrage de feuillet (10) est libéré de manière réversible de l'unité d'éjecteur (36). Dans la première configuration, le dispositif de préhension (50) de l'unité d'éjection (36) saisit une extrémité proximale de l'ancrage de feuillet (10), tandis qu'une extrémité distale de l'ancrage de feuillet (10) est libre du dispositif de préhension (50) pour permettre son implantation dans le feuillet (12). Dans la seconde configuration, le dispositif de préhension (50) est dégagé de l'ancrage de feuillet (10).
