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. The flexible joint may be a rubber tube or a metal tube of a predetermined thickness. 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.
Claims2
A selective brain cooling device, comprising:
- a flexible catheter capable of insertion to a carotid artery of a patient;
- a heat transfer element attached to a distal end of said catheter, said heat transfer element including a plurality of heat transfer segments, further including a flexible metal tube connecting each of said heat transfer segments to adjacent said heat transfer segments, and wherein said flexible metal tube has a wall thickness of between about 0.5 and 0.8 mils and a diameter of between about 2 and 4 mm;
- a plurality of exterior helical ridges on said heat transfer element, said helical ridges to create mixing in a blood flow in the carotid artery;
- and
- an inner coaxial tube disposed within said heat transfer element, said inner coaxial tube being connected in fluid flow communication with an inner coaxial tube within said catheter.
