Abstract
An introducer sheath for a central venous catheter includes a sheath body and a temperature sensor mounted distally on the body. Either the catheter or sheath has a heat exchange region through which coolant is circulated to effect heat exchange with the body, with the coolant temperature being controlled in response to signals from the temperature sensor. Arterial dialysis heat exchange catheters and jugular bulb heat exchange catheters are also disclosed.
