Abstract: 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.

Abstract: A liquid cryogen fluid system for providing cryogenic liquid to a cryoprobe in a cryosurgical system for treating fibroadenomas and other lesions in the body. The system includes a cryoprobe to cryoablate a fibroadenoma with a treatment regimen that takes less time and consumes less cryogen than currently accepted regimens.

Abstract: Embodiments of the present invention relate to a sensor for facilitating detection of a physiological characteristic of a patient. Specifically, one embodiment includes a detector configured to obtain signals from the patient, the signals being indicative of the physiological characteristic and to send the signals to a monitor, and a sensor memory coupled with the sensor and separate from the monitor, the sensor memory storing patient physiological data derived by the monitor from the signals, the patient physiological data being indicative of the physiological characteristic.

Abstract: A liquid cryogen fluid system for providing cryogenic liquid to a cryoprobe in a cryosurgical system for treating fibroadenomas and other lesions in the body. The system includes a cryoprobe to cryoablate a fibroademona with a treatment regimen that takes less time and consumes less cryogen than currently accepted regimens.

Abstract: A method of treating fibroadenomas with optimized freezing periods at a single freezing temperature and minimal thawing time between freezing periods, and a system for accomplishing the method.

Abstract: 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.

Abstract: A cryosurgical system with a cryoprobe, with a bypass valve communicating between the cryogen supply line and the cryogen exhaust line. The bypass valve is located in the cryoprobe, close to the distal tip of the cryoprobe, and is operable to open upon cryogen flow to purge gasses in the supply pathway and then close automatically when cooled by passing flow of liquid nitrogen.
