Abstract:
1. A system for cryoablating a fibroadenoma within the breast of a patient comprising: a cryoprobe adapted for percutaneous insertion through the skin of the breast and into the fibroadenoma; a fluid supply assembly operably connected to the cryoprobe and adapted to provide cooling fluid to the cryoprobe; a control system for controlling operation of the cryoprobe and fluid supply assembly in response to operator input; and input means for entry of a size of the fibroadenoma by the operator operably coupled to the control system; wherein the control system is programmed to operate the cryoprobe with a preset freezing cycle based on the size of the fibroadenoma and controls the cryoprobe to perform a first high power freezing cycle at a first cryogenic temperature and a second low power freezing cycle at a second cryogenic temperature where the second cryogenic temperature is higher than the first cryogenic freezing temperature.
