Title:
METHOD AND APPARATUS FOR HEATING DURING CRYOSURGERY
Document Type and Number:
WIPO Patent Application WO1999015092
Kind Code:
A9
Abstract:
A heating element, preferably temperature controlled, for cryosurgical applications is presented. The cryo-heater (21) comprises a shell (13), and a heating mechanism (23) within the shell. A system for performing cryosurgery is further presented which comprises a mechanism (32) for freezing tissue in a patient in addition to a mechanism (23) for heating other tissue near the tissue being frozen such that essentially only a desired region is frozen. The heating mechanism (23) is disposed near the freezing mechanism (32) or can be used with tissue already frozen. A method for performing cryosurgery on a patient is described which comprises the steps of inserting a cryoprobe (22) into a patient, placing a cryo-heater (21) in contact with the patient adjacent the cryoprobe then activating the cryoprobe, the cryo-heater so that the cryoprobe freezes desired tissue, and the cryo-heater prevents other tissue around the desired tissue from being frozen.
