TREATING URINARY AND OTHER BODY STRICTURES

The invention provides a method and system for treatment of body strictures to restore luminal diameter to within a normal diameter range, in which the stricture is dilated to stretch its lumen to a desired diameter, collagen is exuded near to existing tissue of the stricture so as to be absorbed by that tissue or adhere to that tissue, making a collagen-enhanced tissue structure, and energy is emitted to affect the collagen-enhanced tissue, such as by ablation or by hardening.

Noninvasive devices, methods, and systems for shrinking of tissues

The invention provides improved devices, methods, and systems for shrinking of collagenated tissues, particularly for treating urinary incontinence in a noninvasive manner by directing energy to a patient's own support tissues. This energy heats fascia and other collagenated support tissues, causing them to contract. The energy can be applied intermittently, often between a pair of large plate electrodes having cooled flat electrode surfaces, the electrodes optionally being supported by a clamp structure. Such cooled plate electrodes are capable of directing electrical energy through an intermediate tissue and into fascia while the cooled electrode surface prevents injury to the intermediate tissue, particularly where the electrode surfaces are cooled before, during, and after an intermittent heating cycle. Ideally, the plate electrode comprises an electrode array including discrete electrode surface segments so that the current flux can be varied to selectively target the fascia. Alternatively, chilled 'liquid electrodes' may direct current through a selected portion of the bladder while also cooling the bladder wall, an insulating gas can prevent heating of an alternative bladder portion and the adjacent tissues, and/or ultrasound transducers direct energy through an intermediate tissue and into fascia with little or no injury to the intermediate tissue.

The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

Devices, methods, and systems for shrinking tissues

Devices, systems, and method for treating urinary incontinence generally rely on energy delivered to a patient's own pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder.

Thus, the energy delivery device may be positioned in a withdrawn position in the catheter so that the distal end of the energy delivery device lies within the guide channel, and in an extended position so that the distal end of the energy delivery device is diverted by the diverting region of the guide channel and extends into the tissue to be treated.

Vacuum-assisted systems and methods for treating sphincters and adjoining tissue regions

Systems and methods treat a tissue region at or near a sphincter by deploying a carrier, which carries an electrode that can be advanced to penetrate tissue. Negative pressure is applied through a suction port on the carrier near the electrode, to draw tissue in the tissue region inward against the carrier.

Operative devices that can be removably fitted on catheter bodies to treat tissue regions in the body

A targeted tissue region in a body is treated by a tissue heating element (44) attached to a carrier. The carrier is intended, in use, to be temporarily mounted to an exterior of a catheter body, such as an endoscope. The catheter body is deployed, with the carrier mounted on it, into the targeted tissue region. The tissue heating element (44) is operated, e.g., to form one or more tissue lesions, after which the catheter body is retrieved from the targeted tissue region. The carrier can then be removed from the catheter body, allowing the catheter body to the subsequently used for another purpose.
