摘要：
A combination of a cryoprobe and an introducer is used during surgery to ablate unwanted tissue. The introducer includes a handle portion, a cannula portion, a first internal cavity extending through the handle portion, and a second internal cavity extending through the cannula portion. The first and second internal cavities communicate with one another and are sized to receive a portion of a probe shaft of the cryoprobe therethrough. When the probe shaft is inserted into the first and second internal cavities in the introducer, the distal end of the probe shaft is positionable adjacent the distal end of the introducer, and operation of the cryoprobe facilitates cooling of a portion of the cannula portion at the distal end of the introducer.
