Patent ID: 7517345

Claim:
A medical device for ablating tissue, the device comprising: an elongate probe including a proximal end portion and a distal end portion at which the probe terminates, a cryogenic ablation surface disposed between the proximal end portion and the distal end portion closer to the distal end portion than the proximal end portion, and a malleable section overlapping at least a portion of the cryogenic ablation surface; a flexible sheath, wherein the elongate probe is disposed at least partially within the flexible sheath such that moving the flexible sheath relative to the elongate probe adjusts an exposed length of the cryogenic ablation surface; and a handle coupled to the proximal end portion of the elongate probe, wherein the elongate probe can be selectively shaped to conform to a surface of cardiac tissue such that the cryogenic ablation surface can create a continuous lesion thereon.
