Abstract
A cryoablation device is provide herein which, in an embodiment, includes a catheter shaft and a cryogen return line disposed within the catheter shaft. A cryogen supply line is disposed within the cryogen return line, such that the cryogen supply line, the cryogen return line, and the catheter shaft are all substantially coaxial. A needle tip probe is disposed at a distal end of the cryogen return line and the cryogen supply line extends in a distal direction beyond a distal end of the cryogen return line and into the needle tip probe. An insulating tube is disposed circumferentially around the cryogen return line and within the catheter shaft. An insulating lumen is circumferentially disposed around the return line, between an inner diameter of the catheter shaft and an outer diameter of the insulating tube. A position of the insulating tube is fixed relative to the catheter shaft. A position of the needle tip probe and the cryogen return line is axially and rotationally movable with respect to the insulating tube and the catheter shaft.
