发明名称 Cryoprobe for Low Pressure Systems
摘要 A cryoprobe for use in cryosurgery and other applications comprising a rigid outer tube, an inner coolant inlet tube. a short rigid penetrating segment extending distally from the distal end of the outer tube and a helical-shaped baffle having a heating element disposed about the outer surface of the inlet tube. The baffle is adapted to produce turbulent fluid flow improving heat transfer and is able to warm target tissue during rapid freezing and thawing cycles.

主权项 1. A device comprising: a rigid outer tube; a coolant inlet tube disposed within the outer tube; a short rigid penetrating segment extending distally from a distal end of the outer tube; and a helical-shaped baffle having a heating element disposed about a distal outer surface of the inlet tube, said baffle disposed about a distal section of the inlet tube and terminating proximal of a distal tip of the penetrating segment and adapted to create turbulent fluid flow in fluid and force cryogen towards an inner surface of the outer rigid tube.
