Patent ID: 7959643

Claim:
A heat exchange/intra-aortic counterpulsation system comprising: an elongate heat exchange/counterpulsation catheter having a proximal end, a distal end and a plurality of lumens; a counterpulsation balloon located on the catheter and useable for effecting intra-aortic balloon counterpulsation; a heat exchanger located on the catheter that receives a heat exchange fluid through a lumen of the catheter and has a heat exchange surface for exchanging heat with a patient's flowing blood when positioned within the vasculature of the patient to substantially raise or lower the patient's body temperature without causing the heat exchange fluid to enter the patient's vasculature; at least one drive/control apparatus to i) control inflation/deflation of the counterpulsation balloon in response to received electrocardiogram signals to thereby effect intraortic counterpulsation and ii) deliver heat exchange fluid to the heat exchanger to vary the temperature of the heat exchange surface in response to received temperature signals representative of patient body temperature; a temperature monitoring apparatus for providing temperature signals representative of patient body temperature to the drive/control apparatus; and an electrocardiogram monitoring apparatus for providing electrocardiogram signals to the drive/control apparatus.
