Abstract
A central venous catheter includes coolant supply and return lumens which communicate coolant to and from first and second heat exchange membranes arranged along the distal segment of the catheter. The coolant in the heat exchange membranes removes heat from the patient. Additional lumens are provided for conventional central venous catheter uses.
Claims6
A method for managing patient temperature, comprising:
- disposing a patient in a room of a medical facility,
- cooling a patient to prepare the patient for cardiovascular bypass surgery;
- performing a cardiovascular bypass surgery on the patient;
- re-warming a patient after the cardiovascular bypass surgery is performed;
- advancing a cooling catheter into the patient, the cooling catheter housing an internally circulating coolant having a coolant temperature;
- and
- regulating the coolant temperature to assure that the step of re-warming a patient does not result in hyperthermic patient condition.
