View Patent ↗A cryogenic catheter includes an outer flexible member having at least one cryogenic fluid path through the flexible member. The at least one fluid path is defined by a plurality of flexible members disposed within the outer flexible member.
1. A heat transfer device comprising:
a cryogenic treatment catheter having first and second elongated segments;
a flexible joint connecting the first and second elongated segments; and
a tubular conduit disposed within the first and second elongated segments, the conduit having an inner lumen for transporting a cryogenic fluid to cool the first and second elongated segments.
2. The device of claim 1 , wherein the flexible joint comprises a bellows section.
3. The device of claim 2 , wherein the bellows section is metallic.
4. The device of claim 1 , wherein the first and second elongated segments are flexible and torqueable.
5. The device of claim 1 , wherein the first and second elongated segments are rigid.
6. The device of claim 1 , further including a cryogenic fluid and wherein the cryogenic fluid is a liquid.
7. The device of claim 1 , further including a cryogenic fluid and wherein the cryogenic fluid is a gas.
