Abstract

This invention features an intraluminal ablation device, having an elongated shaft, a handle or adapter on the proximal end of the shaft and a cartridge assembly with an elongated energy transmitting member slidably disposed within and with an insulating jacket on its exterior. The distal end of the intraluminal device and insulating jacket are configured to penetrate tissue, such as prostatic tissue, which is to be ablated. One embodiment of the intraluminal device of the invention has a mechanism to fix the relative positions of the energy transmitting member and the insulating jacket surrounding the energy transmitting member to adjust the length of the distal extremity of the energy transmitting member which extends beyond the distal end of the insulating jacket. In another embodiment the cartridge assembly is provided with a mechanism to be advanced beyond its operating position and then be retracted to its operating position to minimize tenting at the penetration site. In yet another embodiment means are provided to prevent delivery of ablation energy unless the electrodes are in their proper position for the procedure.
