Abstract
The device comprises a container housing for enveloping, at least partially, the ventricular region of the myocardium. To the inner surface of the container housing are applied membrane means which define pumping chambers between the inner surface and the myocardial wall. A pumping fluid is fed selectively to these chambers to cause expansion of the chambers and consequent compression of the myocardial wall.
Claims5
An implant device for sustaining the activity of the myocardium comprising:
- a container housing including two substantially separate rigid shells adapted to envelop the left ventricular wall and the right ventricular wall of the myocardium, respectively, and a biocompatible fabric connecting strip bridging a space formed between said shells between said shells and securely attached to said shells wherein said fabric extends in said space between said shells in correspondence with the interventricular sulcus for attachment thereto by suturing,
- membrane means secured to the inner surface of said shells defining two separate independent pumping chambers each adapted to act independently on the left ventricular wall and the right ventricular wall of the myocardium, respectively, and means for selectively and separately feeding fluid to said two chambers so as to cause expansion of the chambers and consequent compression of the left ventricular wall and the right ventricular wall of the myocardium.
