CIRCULATORY SUPPORT SYSTEM AND METHOD OF USE FOR ISOLATED SEGMENTAL PERFUSION

摘要

A circulatory support system and method for circulatory support are describe d for performing cardiopulmonary bypass using differential perfusion and/or isolated segmental perfusion of the circulatory system. The circulatory support system includes one or more venous cannulae for draining blood from the venous side of the patient's circulatory system, one or more arterial cannulae for perfusing the arterial side of the patient's circulatory system , and one or more blood circulation pumps connected between the venous cannula e and the arterial cannulae. The arterial cannulae and the venous cannulae of the circulatory support system may take one of several possible configurations. The circulatory support system is configured to segment a patient's circulatory system into one or more isolated circulatory loops. Th e circulatory loops may be isolated from one another and/or from the remainder of the patient's circulatory system on the venous side, as well as on the arterial side, for isolated closed loop circulatory support of separate orga n systems. The circulatory support system is suitable for use in minimally- invasive cardiac surgery, using thoracoscopic, port-access or minithoracotom y techniques, or for standard open-chest cardiac surgery.
