Abstract: A device for selectively grasping and cutting tissue includes an outer tube having a longitudinal axis and an open proximal end and an open distal end; also an inner tube within the outer tube, the inner tube having a longitudinal axis and an open distal end and an open proximal end; as well as a cup-shaped cutting member mounted to the distal end of the outer tube, the cutting member being larger in diameter than the diameter of the outer tube, the cutting member including one or more cutting surfaces around the lip of the cup-shaped cutting member, the one or more cutting surfaces facing in a distal direction; also, a cylindrical cup-shaped cutting member mounted to the distal end of the inner tube; the cutting member including one or more cutting surfaces mounted around the lip of the cylindrical cup-shaped cutting member facing in a proximal direction; and, the inner tube is of a diameter to be slidably movable within the outer tube; whereby moving the inner tube alternately in distal and proximal directi

Abstract: A cryotherapy system comprises a cryoprobe comprising, for example, either an electronic module including a memory or a response module operable to respond to a query signal with a response signal. A communications interface uses these modules to establish a unique identification of the cryoprobe, and a control module regulates delivery of cryogen to the cryoprobe according to calculations at least partially based on stored data associated with that unique cryoprobe identification.
