摘要: A cryosurgical system using a low-pressure liquid nitrogen supply, which requires only 0.5 to 15 bar of pressure to provide adequate cooling power for treatment of typical breast lesions. The pressure may be provided by supplying lightly pressurized air into the dewar, by heating a small portion of the nitrogen in the dewar, or with a small low pressure pump.

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.
