发明名称 Treatment of sphincters with electrosurgery and active substances
摘要 <p>The invention provides a method and system for treatment for body structures, especially internal body structures involving unwanted features or other disorders, that does not require relatively invasive surgery, and is not subject to other drawbacks noted with regard to the known art. A relatively minimally invasive catheter including a contained cooling element is inserted into the body. The distal and proximal end of the catheter are extended or retracted or some combination thereof so as to achieve optimal delivery of treatment. Treatment of the body structures is applied using the electrodes embedded in the cooling element, and the unwanted features or disorders are relatively cured using the applied treatments. In a preferred embodiment, the applied treatments can include application of energy or substances, including application of energy (such as of radio frequency energy, microwave energy, or laser or other electromagnetic energy) or substances (such as collagen or other bulking, plumping, or shaping agents; saline or other energy-receiving electrolytes; astringents or other debulking, reducing, or shaping agents; antibiotics or other bioactive, chemoactive, or radioactive compounds). In a preferred embodiment, more than one applied treatment can be performed, either in conjunction, in parallel, or seriatim, so as to achieve a combined effect more substantial than any one individual such applied treatment. &lt;IMAGE&gt;</p>
