Biventricular circulatory assist system and method

摘要

A biventricular circulatory support system for a human patient is described. A mechanical first pump for assuming at least a part of the pumping load of the patient's left ventricle is implanted in the patient. A second pump for assuming at least a part of the pumping load of the patient's right ventricle is also implanted. The second pump includes a surgically prepared skeletal muscle pedicle with nerves and blood supply substantially intact. The muscle pedicle is applied directly to the right ventrical or is applied to an artificial pump sac. Electrical signals are applied to the first and second pumps as appropriate to cause pumping action in a predetermined relationship.
