Abstract:
An endovascular catheter device for controlling the temperature of at least a portion of the body of a human or veterinary patient and for providing gas exchange with the patient's blood, said device comprising:a catheter shaft that is insertable into the patient's vasculature; a heat exchanger attached to the catheter shaft, the heat exchanger having a heat exchange surface through which heat is exchanged and with the patient's blood when the catheter shaft is inserted into the patient's vasculature; a gas exchange element attached to the catheter shaft, the gas exchange element comprising at least one gas-permeable membrane that is separate from said heat exchanged surface are through which gas may be exchanged with the patient's blood when the catheter shaft is inserted into the patient's vasculature, a gas inflow lumen and a gas outflow lumen connected to a gas exchange device for carrying gas to and from the gas-permeable membrane; controller apparatus connected to a temperature regulator and a gas delivery regulator for controlling the heat exchange and gas exchange being performed by the catheter device; and a blood gas concentration monitoring device connected to the controller.
