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.

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.

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.

The invention provides improved methods for modifying collagenous tissues, particularly for treating urinary incontinence in a noninvasive manner. The methods typically include inserting a probe into a patient's urethra, transmitting electromagnetic energy from the probe to a collagneous target tissue, and cooling the tissue in the vicinity of the probe. The probe may include an expandable element at or near the distal end that is configured to expand within the patient's bladder. The expandable element may anchor the probe before or during treatment.
摘要:
Devices and methods for treating tissue with microwave energy used in applications such as destroying a soft tissue by microwave ablation and/or creating point, line, area or volumetric lesions. Various embodiments of flexible, low-profile devices are also disclosed where such device can be inserted non-invasively or minimally invasively near or into the target tissue such as cardiac tissue. The devices disclosed herein comprise antennas wherein the field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas use unique properties of microwaves such as interaction of a microwave field with one or more conductive or non-conductive shaping elements to shape or redistribute the microwave field.
