First Claim
Patent Images
1. A catheter device comprising:
- a catheter body having a distal end, a first lumen and a second lumen;
an elongate member which extends distally from the catheter body, said elongate member having a plurality of spaced-apart heat exchange member-receiving features therein or thereon;
at least one heat exchange member disposed on the elongate member and connected to said first and second lumens such that fluid may circulate in a distal direction through the first lumen, then through said at least one heat exchange member, then in a proximal direction through the second lumen;
a third lumen extending through the catheter body; and
an elongate luminal member attached to the catheter body and extending substantially parallel to the elongate member, said elongate luminal member which has a lumen extending longitudinally therethrough;
wherein portions of said at least one heat exchange member are captured between the elongate member and the elongate luminal member.
