The present invention includes systems, methods, and apparatus configured to close an internal tissue opening, such as an internal tissue opening cased by an atrial septal defect including a patent foramen ovale defect, ventricular septal defect, patent ductus arterosus defect, or the like. For example, a closure device includes a right anchor cooperatively coupled with a left anchor, where the right anchor and left anchor are configured to be positioned about the internal tissue opening. The left and/or right anchor are configured to close the internal tissue opening in one instance, and to provide tissue stimulating or growth-encouraging substances at the tissue opening. Additional aspects of the invention relate to shape, formation, positioning, and detachment of the closure device about the internal tissue opening.

L'invention concerne des systèmes, des procédés et des appareils conçus pour fermer une ouverture de tissu intérieur, telle qu'une ouverture de tissu intérieur due à une communication interauriculaire comprenant une persistance du foramen ovale, une communication interventriculaire, une persistance du canal artériel ou toute autre anomalie analogue. Par exemple, un dispositif de fermeture comprend un ancrage droit couplé de manière coopérative à l'ancrage gauche. L'ancrage droit et l'ancrage gauche sont conçus pour être positionnés autour de l'ouverture de tissu intérieur. L'ancrage droit et/ou l'ancrage gauche sont conçus pour fermer l'ouverture de tissu intérieur dans un exemple et pour fournir des substances stimulant le tissu ou la croissance au niveau de l'ouverture du tissu. D'autres aspects de l'invention concernent la forme, la formation, le positionnement et le détachement du dispositif de fermeture autour de l'ouverture du tissu intérieur.
