Abstract
A cardiopulmonary bypass system includes an aortic balloon cannula and a fluid flow cannula configured for connection to a cardiopulmonary bypass pump. The aortic balloon cannula includes an elongated tube device with first and second inflatable balloons mounted on the tube device and first and second lumen sized to communicate blood from the cardiopulmonary bypass pump to the patient's aorta. The cardiopulmonary bypass pump is configured to selectively deliver blood to the patient through the aortic balloon cannula and/or the fluid flow cannula at first, second and third temperatures.
Claims53
A cardiopulmonary bypass system, comprising:
- an aortic balloon cannula including an elongated tube device having an exterior, internal and external extremities and including a first lumen having a first internal communication hole in said internal extremity and configured to, when in an operative position, communicate fluid between said first internal communication hole and a cardiopulmonary bypass pump, said tube device further including a pilot lumen leading from a balloon location on said tube device to said external extremity, and a fluid flow resisting balloon on the exterior of said tube device at said balloon location and in fluid communication with said pilot lumen;
- and
- a fluid flow cannula for insertion into a vessel of such patient, said fluid flow cannula configured to, when in an operative position, communicate fluid between such vessel and the cardiopulmonary bypass pump.
