Abstract
A intravascular heat exchange catheter includes a catheter body having a proximal end connectable with a heat exchange fluid source and a distal end insertable into the vasculature of a patient to facilitate heat transfer with flowing blood. The core has at least one heat exchange fluid lumen for circulating heat exchange fluid within the catheter body. A heat exchanger, e.g. a balloon surrounds a portion of the proximal end of the catheter. The heat exchanger is in fluid communication with the heat exchange fluid lumen for enabling heat exchange fluid from the heat exchange fluid source to circulate through the core and the balloon. A wire, or similar retainer, wraps around the balloon to seal the balloon against the core, forming at least two heat exchange lumens between the balloon and the core.
