System and method for performing MRI-guided cryosurgery are provided. The system includes: (a) an MRI magnet for accommodating a patient, the MRI magnet having at least one opening for enabling access of a surgeon to the patient, the MRI magnet including at least one channel extending therethrough for receiving a line member of a surgical device; (b) a surgical device, including: (i) an operating member for operating the patient; (ii) a control member for controlling the operating member, the control member being positioned externally to the MRI room; (iii) a line member having a first end connectable to the operating member and a second end connectable to said control member, wherein at least a portion of the line member is received within the channel of the MRI magnet. Preferably, the line member includes an underground portion extending through an underground channel. The MRI magnet may include an interface member for connecting the operating member thereto. Preferably, the operating member is a cryogenic probe including a Joule-Thomson heat exchanger, the line member is a gas tube, and the control member includes a gas container for providing high pressure gas to the cryogenic probe via the gas tube. Preferably, the control member includes a microprocessor for controlling the operation of said surgical device. <IMAGE> |
