Claims
- 1. An endovascular heat transfer device, comprising:
a working fluid supply, including a gear pump; a flexible catheter capable of insertion to a selected vessel in the vascular system of a patient; a heat transfer element attached to a distal end of said catheter, said heat transfer element comprising a plurality of heat transfer segments, each said heat transfer segment being encompassed by a smooth surface; and an inner tube disposed within said heat transfer element, said inner tube being connected in fluid flow communication with said gear pump.
- 2. The device recited in claim 1, wherein said gear pump is a helical tooth gear pump.
- 3. A heat transfer device, comprising:
a flexible catheter capable of insertion to a vessel in the vascular system of a patient; a plurality of heat transfer segments attached to a distal end of said catheter; a flexible joint connecting each of said heat transfer segments to adjacent said heat transfer segments; and a smooth flexible tube connecting at least some of said heat transfer segments to adjacent said heat transfer segments.
- 4. An endovascular heat transfer device, comprising:
a flexible catheter capable of insertion to a selected vessel in the vascular system of a patient; a heat transfer element attached to a distal end of said catheter, said heat transfer element comprising a plurality of heat transfer segments, each said heat transfer segment being encompassed by a smooth surface; and an inner tube disposed within said heat transfer element, said inner tube being adapted to supply heat transfer fluid to the interior of said heat transfer element.
