CA 2525433

A system for improving cardiac function is provided. A foldable and expandable frame having at least one anchoring formation is attached to an elongate manipulator and placed in a catheter tube while folded. The tube is inserted into a left ventricle of a heart where the frame is ejected from the tube and expands in the left ventricle. Movements of the elongate manipulator cause the anchor to penetrate the heart muscle and the elongate manipulator to release the frame. The installed frame minimizes the effects of an akinetic portion of the heart forming an aneurysmic bulge.

L'invention concerne un système destiné à améliorer la fonction cardiaque. Une structure pliable et déployable comprenant au moins un élément d'ancrage est fixée à un manipulateur allongé et disposée dans un tube de cathéter à l'état plié. Le tube est inséré dans un ventricule gauche d'un coeur, la structure étant alors éjectée du tube et déployée dans ce ventricule gauche. Les mouvements du manipulateur allongé amènent l'élément d'ancrage à pénétrer dans le muscle cardiaque et le manipulateur à libérer la structure. La structure installée permet de réduire les effets causés par une partie akinétique du coeur formant un renflement anévrismal.
