<p>Apparatus for remodeling in the urinary tract of a human female comprising a remodeling device (61) having a shaft (62) with a profile and with proximal and distal extremities (63, 63). A handle (71) is secured to the proximal extremity of the shaft (62). Pluralities of needle electrodes (102, 104) are carried by the distal extremity of the shaft (62) and are disposed circumferentially of the shaft (62). A pusher is carried by the handle for moving the needle electrodes from a retracted position in which they are within the profile of the shaft (62). A pump (147) is connected to the handle for supplying a cooling liquid to the distal extremity of the shaft so that it exits from the shaft in the vicinity of the needle electrodes (102, 104). An RF generator (156) is coupled to the handle (71) and to the needle electrodes (102, 104) for supplying radio frequency energy to the needle electrodes (102, 104).</p> |
