ABSTRACT:
A system to provide cardiac assistance to a patient's heart. The system includes a pulse generator adapted to be coupled to patient's heart and adapted to be coupled to a skeletal muscle ventricle (SMV). The system further includes a sewing ring adapted to be coupled to the SMV and adapted to be coupled to the patient's circulatory system, the sewing ring has a first annular ring and a second annular ring, the first and second annular rings having means for limiting the formation of tissue fibrosis in the vicinity of the first and second annular rings. In the preferred embodiment this comprises means for being more flexible at a distal end than a proximal end, which is accomplished by providing a series of holes in each of the rings. The holes preferably have a range of diameters, the holes located furthest away from the distal end of each ring have smaller diameters than compared to those holes located nearer to the distal end of the same ring.
