A vapor delivery system and method is provided that is adapted for ablating bladder tissue to treat overactive bladder (OAB). The vapor delivery system includes an anchor tip configured anchor the system in the bladder while condensable vapor is delivered to target tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the target tissue of the bladder, which can include a surface sensor of the bladder responsible for creating an urge incontinence sensation. The vapor delivery system includes a vapor source that provides a high quality vapor for delivery to tissue.

Apparatus and methods are provided to concentrate energy delivery in non-superficial target tissue within a trigone region of a human bladder wall to modulate bladder function.

An antenna system for tissue ablation includes an energy transmission member, a conductive hollow coil member coupled to the energy transmission member, and a fluid cooling system coupled to the conductive hollow coil member for providing a flow of cooling fluid through a member lumen of the conductive hollow coil member for cooling the conductive hollow coil member. In some examples, at least one of the antenna body, a choke member, and a hybrid choke member includes the conductive hollow coil member. In some examples, the hybrid choke member includes a choke portion wound around a portion of the energy transmission member, an antenna body portion wound around a portion of the energy transmission member, and an insulator portion extending between the choke portion and the antenna body portion. In some examples, the antenna system includes a sheath extending over the energy transmission member and the conductive hollow coil member.

The present invention discloses medical systems and methods adapted for the delivery of various medical components such as microwave antennas within or on a body for performing one or more medical procedures. Several embodiments herein disclose medical systems comprising a combination of one or more medical components and one or more elongate steerable or non-steerable arms that are adapted to mechanically manipulate the one or more medical components. Several embodiments of microwave antennas are disclosed that comprise an additional diagnostic or therapeutic modality located on or in the vicinity of the microwave antennas.

A method for treating pelvic pain and or chronic prostatitis, and or overactive bladder symptoms. Energy, preferably in the form of infrared or near infrared wavelength light may be applied across the vaginal tissue or rectal tissue to treat pelvic pain and or chronic prostatitis. This method of energy application may cause local heating, alteration of cellular respiration, and alterations of local blood flow resulting in decreased muscle spasm, and or decreased pain, and or decreased overactive bladder symptoms. The method of the present invention may effectively treat chronic pelvic pain and or the symptoms of chronic prostatitis. The method of the invention may combine massaging of tissue with irradiation of same.

A treatment device for treatment of overactive bladder conditions operates to suction to grasp and conform a mucosal tissue of the bladder wall to a portion of the tissue treatment device, and deliver energy to non-superficial target tissue at a substantially uniform depth from the mucosal tissue. The tissue treatment device incorporates multiple instruments for different functions needed to treat overactive bladder conditions. The tissue treatment device provides simplified interfaces and mechanisms for operating each of the multiple instruments in a controlled manner. Further, the tissue treatment device is configured to have a low and smooth profile that permits the tissue treatment device to be used without a tubular sheath.
