<p>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 flexible cylindrical sleeve having a distal end and a proximal end, the flexible cylindrical sleeve defining a lumen therewithin; the ring further features a means for maintaining the patency of the lumen, the means for maintaining the patency positioned on the proximal end. In the preferred embodiment, the means for maintaining the patency of the lumen is a reinforcing ring mounted to the proximal end of the flexible cylindrical sleeve, preferably a silicone ring.</p> |
