摘要:
Devices, systems, and method for treating urinary incontinence generally relying on energy delivered to a patient's pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder. The energy will preferably be applied to the endopelvic fascia and/or an arcus tendineus fascia pelvis. A variety of devices and methods are provided for applying gentle resistive heating of these and other tissues to cause them to contract without imposing significant injury on the surrounding tissue structures. By applying sufficient energy over a predetermined time, the tissue can be raised to a temperature which results in contraction without significant necrosis or other tissue damage. By selectively contracting the support tissues, the bladder neck, sphincter, and other components of the urinary tract responsible for the control of urinary flow can be reconfigured or supported in a manner which reduces urinary leakage.

A catheter delivers an electrode within a vein for a minimally invasive treatment of varicose veins and venous insufficiency using RF energy. The catheter is introduced into a patient and positioned within the section of the vein to be treated. The electrode radiates high frequency energy towards the vein, and the surrounding venous tissue becomes heated and begins to shrink. The catheter includes a controllable member for limiting the amount of shrinkage of the vein to the diameter of the member. The electrode remains active until there has been sufficient shrinkage of the vein. The extent of shrinkage of the vein may be detected by fluoroscopy. After treating one section of the vein, the catheter and the electrode can be repositioned intraluminally within the vein to treat different sections of the vein until all desired venous sections and valves are repaired and rendered functionally competent.

A device is disclosed for locating and treating an infarct scar in a heart. The device includes a catheter, a collapsible heater and energizing means connected to the collapsible heater for energizing the collapsible heater to raise the temperature of the infarct scar to a temperature sufficient to reduce the surface area of the infarct scar.

This relates to a device for treating lung disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airways of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the airways to constrict and/or reduces the resistance within the airway to the flow of air through the airway.

Methods and devices are provided for reconfiguring a tissue within a hollow body organ using an entirely endoscopic approach in order to effectively reduce flow of fluid contents into a second hollow body organ in fluid communication with the first.
摘要:
An ultrasonic medical or surgical device creates holes in heart tissue utilizing an ultrasonic needle or probe. The ultrasonic needle is inserted into heart tissue and activated to cause cavitation of fluid surrounding the needle. The cavitation heats the surrounding tissue and causes reversible tissue damage. The ultrasonic device consists of a transducer, a needle, and a regulator. The device can be a hand held device for external application or may be a catheter device for performing a minimally invasive procedure. A temperature sensor may be positioned on the needle for sensing a temperature of the heart tissue in which the needle has been inserted.

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. 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.
摘要:
A device and method for treating collapsed bronchial tubes found in patients with chronic obstructive pulmonary disease and asthma are provided. The device includes an elongated member having a heating element that comprises one or more energy delivery members. The method includes heating the bronchial tube to cause at least a portion of the cross links of the collagen in the wall to unlink/open and subsequently form new cross links after the collagen fibers have realigned. The procedure effectively reinforces the structural integrity of the wall and thereby prevents the lumen from collapsing.
