Abstract
A cryoprobe is used during surgery in a human body to remove unwanted tissue. The cryoprobe includes a first gas supply line and a second gas supply line for delivering a supply of cryogenic gas from at least adjacent a proximal end to at least adjacent a distal end of the cryoprobe. The cryoprobe further includes a first gas return line and a second gas return line for returning the supply of cryogenic gas from at least adjacent the distal end to at least adjacent the proximal end of the cryoprobe. At least a portion of the first gas supply line is received in the first gas return line. A transition portion having at least one internal cavity and an aperture from the at least one internal cavity to an exterior portion of the transition portion is also included in the cryoprobe. The transition portion is provided to facilitate at least the transfer of the cryogenic gas from the second gas return line to the first gas return line, so that the cryogenic gas can flow adjacent the first gas supply line on its way to the proximal end of the cryoprobe.
