The present disclosure relates to the field of tissue mapping and ablation. Specifically, the present disclosure relates to expandable medical devices for identifying and treating local anatomical abnormalities within a body lumen. More specifically, the present disclosure relates to systems and methods of focal treatment for overactive bladders.

A method of creating multiple thermal lesions in tissue around urethra using needle electrodes inserted essentially parallel to urethra.

The systems and methods in accordance with the principles of the invention can treat urinary stress incontinence by treating target tissue in proximity to the urethra and/or bladder neck. A method for treating urinary stress incontinence in a subject can included non-invasively heating a subsurface region of a target tissue to induce remodeling of the subsurface region at the anterior and/or posterior regions of the vagina. The system can include: a controller and a probe having a distal end configured for non-invasive contact with a surface of a target tissue to transfer energy to the target tissue based on treatment parameters. The probe distal end can have two treatment surfaces spaced apart a distance equal to at least a width of a urethra.

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.

A comfortable single-piece male incontinence control device (100) permitting conscious micturition without adjustment or removal of the device (100). The device having a continuous loop of an elastic compression band (110) configured and arranged to securely encircle a flaccid penis P without inflicting penile ischemia, and a bump (120) on the elastic compression band (110) projecting inward into the lumen (119) defined by the band (110) for pressing against and constricting the urethra U of a wearer W.

An electro-mechanical-type handpiece is specially designed to be used with a laser Generator, particularly those that use a CO.sub.2 laser and provide a laser beam in fractional mode. The fractional mode laser beam is provided in a pattern of homogeneous points aligned in rows, columns or diagonally, and such a pattern allows internal tissue along an entire length of a vagina of a patient to be treated and a pelvic floor of the patient to be retracted, such that a urinary bladder of the patient is elevated and, owing to the change in angle thereof, slight or moderate losses of urine are resolved or improved. In addition, the device can be used to treat the inner surface of the vagina of the patient, reducing vaginal laxity caused by childbirth and age.

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.
