Abstract
A cryosurgical instrument including: a core, a cryogen delivery tube, a cryogen return tube, and a shaft surrounding the core and the tubes. The shaft has a pointed distal end and a proximal end adapted and configured to receive an inflow of cryogen and to exhaust a flow of expanded cryogen. The cryogen delivery tube and the cryogen return tube both have respective helical portions that spiral around the core. The helical portions of the tubes are in fluid tight contact with the core and an inner surface of the shaft. The helical portions of the tubes spiral about the core in an alternating arrangement such that they alternate along a length of the core. The core and the helical portions of the delivery tube and the return tube comprise centrifugal phase separators.
