Patent

CA 2701453

The present invention relates to an external heart device, having a layered band dimensioned to be received around a patient's heart, which also includes at least one fillable chamber between the layers in the band that functions to apply localized pressure to the outside of the heart when filled. More particularly, the fillable chambers are positioned such that they exert an inward radial force on a heart valve. Areas between the fillable chambers may also be sized and positioned to form a bridge of little to no pressure over the vascular structures of the heart.

La présente invention porte sur un dispositif cardiaque externe, comportant une bande en couches dimensionnée pour être reçue autour du cur d'un patient, qui comprend également au moins un compartiment pouvant être rempli entre les couches dans la bande, qui sert à appliquer une pression localisée à l'extérieur du cur lorsqu'il est rempli. Plus particulièrement, les compartiments pouvant être remplis sont positionnés de telle sorte qu'ils exercent une force radiale vers l'intérieur sur une valvule cardiaque. Des zones entre les compartiments pouvant être remplis peuvent également être dimensionnées et positionnées pour former un pont de pression faible à nulle sur les structures vasculaires du cur.
