The present invention is related to a radiofrequency treatment probe and method delivering radiofrequency for controlled heating of tissue within the vagina for the treatment of vaginal laxity. The treatment probe may include a curved, rounded disposable treatment tip that may be designed to accommodate vaginal anatomy. An electrode assembly may be coupled to the treatment tip, wherein the electrode coupled to the treatment tip may be configured to transfer radiofrequency energy through vaginal skin surface to the tissue. A temperature measuring feature may include or be coupled to the electrode assembly, wherein the electrode assembly may be configured to regulate and maintain a pre-determined skin temperature. A radiofrequency handle may be configured to connect to a disposable treatment tip. A connector may be configured to connect to the radiofrequency handle to a radiofrequency generator. A protective apparatus may be configured to protect the radiofrequency handle.

A non-invasive and permeable RF diagnosis and treatment equipment and its catheter are provided. The catheter which comprises a tube body, a RF electrode array and a flexible protecting net has a retractable cavity, and the RF electrode array is attached to an outer surface of the retractable cavity; the flexible protecting net surrounding outside of the RF electrode array has a connector connected with the tube body and multiple holes. The retractable cavity has a smaller volume contraction state and a larger volume expansion state. Using the catheter, when inserting or pulling out the catheter, the RF electrode array will not contact the inner wall of the organ, but the flexible protecting net contacts the inner wall of the organ. In this way, the scratch of the inner wall of the organ caused by the RF electrode array can be minimized or even avoided through the flexible protecting net.

An ablation instrument comprises an elongate shaft having a cannula channel and a scope channel, and an electrode disposed in the cannula channel. The electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel. The ablation instrument further comprises a distal head coupled to the elongate shaft and configured for engaging tissue.

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.

Devices and methods that provide minimally-invasive approaches to performing treatments on soft tissue, such as that found in the bladder using various natural access paths such as transvaginal and transurethral. Treatments include the application of energy to nerves found in, under and around the trigone region of the bladder.

A multi-angular ultrasound device. Multi-angular ablation patterns are achieved by a catheter-based ultrasound transducer having a plurality of transducer zones. A multi-chambered balloon is positioned on the catheter.

An antenna system for tissue ablation includes an energy transmission member, a conductive hollow coil member, and a fluid cooling system. The energy transmission member has an inner conductor, an outer conductor, and a dielectric layer between the inner and outer conductors. A portion of the dielectric layer extends distally of a distal end of the outer conductor. The conductive hollow coil member includes a member lumen within a length of the conductive hollow coil member. The conductive hollow coil member is coiled around the portion of the dielectric layer and is separate from the inner conductor. The conductive hollow coil member extends along an entire length of the outer conductor of the energy transmission member. The fluid cooling system is coupled to the conductive hollow coil member for providing a flow of a cooling fluid through the member lumen for cooling the conductive hollow coil member.

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.
