Partitioning device for separating a patient~s heart chamber into a productive portion and a non-productive portion. The device is particularly suitable for treating patients with congestive heart failure. The partitioning device has a frame-reinforced (13), expandable membrane (11) which separates the productive and non-productive portions of the heart chamber. The proximal ends of the ribs (16) of the frame have tissue penetrating elements (21) about the periphery thereof which are configured to penetrate tissue lining the heart wall at an angle approximately perpendicular to a longitudinal axis of the partitioning device. The partitioning device has a hub (12) with a non- traumatic distal end to engage the ventricular wall.

L'invention concerne un dispositif de séparation qui permet de séparer la cavité cardiaque d'un patient en une partie productive et une partie non productive. Ce dispositif convient particulièrement pour traiter des patients souffrant d'insuffisance cardiaque congestive. Le dispositif de séparation possède une membrane expansible à cadre renforcé, qui sépare les parties productive et non productive de la cavité cardiaque. Les extrémités proximales des nervures du cadre comportent sur leur pourtour des éléments de pénétration de tissu qui sont configurés pour traverser les tissus qui enveloppent la paroi du coeur à un angle presque perpendiculaire à l'axe longitudinal du dispositif de séparation. De plus, le dispositif de séparation possède un embout pourvu d'une extrémité distale non traumatique qui s'applique sur la paroi ventriculaire.
