Abstract
A selective organ heat transfer device with deep irregularities in a turbulence-inducing exterior surface. The device can have a plurality of elongated, articulated segments, each having a turbulence-inducing exterior surface. A flexible joint connects adjacent elongated, articulated segments. An inner lumen is disposed within the heat transfer segments. The inner lumen is capable of transporting a pressurized working fluid to a distal end of the heat transfer element.
Claims7
A method of treating an organ, comprising:
- inserting a heat transfer element into a feeder artery from a distal location;
- circulating a working fluid through said heat transfer element to accomplish heat transfer;
- inducing mixing in said working fluid;
- and
- changing the temperature of the heat transfer element to modify the temperature of the blood in the feeder artery, thereby selectively modifying the temperature of the organ.
2 more elements
A catheter for modifying the temperature of a body, comprising:
- a catheter shaft;
- first and second lumens in said catheter shaft;
- a heat transfer tip adapted to transfer heat between blood surrounding said heat transfer tip and an interior of said heat transfer tip;
- a working fluid circulated in through said first lumen and out through said second lumen to accomplish said heat transfer;
- and
- mixing-inducing structures on said interior of said heat transfer tip, said mixing-inducing structures being shaped and sized to induce mixing in said working fluid.
