HEART IMPLANT

The invention relates to a heart implant, particularly being configured to reduce or eliminate a heart valve insufficiency after implantation into the heart, comprising a closure element (4) being configured to be positioned within the heart valve annulus, particularly being configured to close or at least to reduce a remaining gap between closing valve leaflets, the closure element (4) comprising an expandable sheath (5), particularly a sheath to be contacted by coapting leaflets after implantation, and an internal supporting structure supporting the sheath (5) at the inner surface of the sheath (5), particularly the expandable sheath (5) and internal supporting structure being compressible, an anchoring element (7) being attached to the closure element (4) for fixing the implant in the heart, preferably for non-invasive fixing by surface contact between the exterior surface of the anchoring element (7) and an interior surface of a heart lumen, preferably the atrium, wherein the supporting structure is formed of at least one fluid fillable, preferably also expandable conduit structure (1). The invention furthermore relates to a system comprising an implant and a filling device (9) for filling a fluid into the conduit structure (1) of the implant, wherein the system is configured to fill a first fluid, preferably saline solution, into the conduit (1) in order to effect the expansion of the closure element (4) and configured to flush the filled conduit structure (1) with a second fluid, preferably a polymerizing fluid. The invention furthermore relates to a method of treating a heart valve insufficiency. L'invention concerne un implant cardiaque, étant en particulier conçu pour réduire ou éliminer une insuffisance valvulaire cardiaque après implantation dans le cœur, comprenant un élément de fermeture (4) conçu pour être positionné à l'intérieur de l'anneau valvulaire cardiaque, étant en particulier conçu pour fermer ou au moins pour réduire un espace restant entre les lames valvulaires de fermeture, l'élément de fermeture (4) comprenant une gaine expansible (5), en particulier une gaine devant être mise en contact par coaptation des lames après implantation, et une structure de support interne supportant la gaine (5) au niveau de la surface interne de la gaine (5), en particulier la gaine expansible (5) et la structure de support interne étant compressibles, un élément d'ancrage (7) étant fixé à l'élément de fermeture (4) pour fixer l'implant dans le cœur,
