Abstract

An ablation assembly includes a handle, a catheter assembly and a connector locking assembly. The catheter assembly includes: a catheter shaft, a balloon and a connector at the distal and proximal ends of the catheter shaft, and a delivery tube extending between there between. The connector includes a connector body secured to the proximal end and a plug secured to the delivery tube, the plug and delivery tube movable axially and rotationally. The handle includes an open portion receiving the plug and the connector body. The connector locking assembly includes: means for simultaneously automatically connecting the plug and the connector body to the handle to place the connector in a load state prior to use, and means for automatically releasing the connector body and thereafter the plug from the handle to place the connector in an eject state to permit the connector to be removed from the handle.
