Abstract
A cryoprobe sheath has at least one positioning element that deploys and retracts to permit the insertion of the cryoprobe into a uterus without using ultrasound or fluoroscopy. Deployment of the positioning element(s) positions the cryoprobe within the uterus permitting even cooling to facilitate cryoablation. The positioning element(s) and sheath may be withdrawn either after tacking the cryoprobe in position by a momentary activation or after a complete activation cycle, with each positioning element pulling through frozen medium in its own track. A guide and filler tube may be employed to infuse the correct quantity of thermally conductive medium into the uterus for cryoablation. The guide and filler tube allows fluid volume and pressure to be measured to avoid inadvertently breaching the uterine wall.
