First Claim
Patent Images
1. A heat exchange catheter, comprising:
- a body;
at least one coolant supply lumen and at least one coolant return lumen in the body; and
at least one heat exchange element communicating with the lumens and configured for placement within a blood vessel of a patient such that blood can flow past the heat exchange element, wherein coolant is circulated through the body in a closed loop, the heat exchange element including plural longitudinally-spaced generally square-shaped links at least when coolant flows through the catheter.

11. A heat exchange catheter, comprising:
-
a body;
at least one coolant supply lumen and at least one coolant return lumen in the body; and
at least one heat exchange element communicating with the lumens and configured for placement within a blood vessel of a patient such that blood can flow past the heat exchange element, wherein coolant is circulated through the body in a closed loop, the heat exchange element including plural longitudinally-spaced links at least when coolant flows through the catheter, each link being configured to establish a single coolant path through the link that directs coolant through the link in a proximal to distal direction for at least a first part of the path and in a distal to proximal direction for at least a second part of the path. - View Dependent Claims (12, 13, 14, 15, 16)
