Abstract
An intra-aortic balloon pump catheter system (apparatus and method) includes a pumping element for pumping a patient's blood and one or more heat exchange for exchanging heat with the patient's blood to provide efficient temperature control of the patient. The catheter may also provide access to the patient's central venous system through one or more infusion lumens and infusion ducts. An elongate body defines an inflation lumen that conveys an inflation fluid to and from the pumping element, and an inflow lumen and an outflow lumen that supply heat exchange fluid to and from each heat exchange element. The pumping element may include an everting pumping balloon that expands out of a cavity in the elongate body after insertion of the catheter. The catheter may have an internal heating element that heats or cools the heat exchange fluid.
