Apparatus for applying energy to biological tissue including the use of tumescent tissue compression

摘要: An electrode catheter is introduced into a hollow anatomical structure, such as vein, and positioned at treatment site within the structure. Tumescent fluid injected tissue surrounding to produce tumescence of which then compresses vein. The solution may include an anesthetic, further vasoconstrictive drug that shrinks blood vessels. tumescent swelling in causes structure become compressed, thereby exsanguinating site. Energy applied by apposition with vein wall create heating effect. effect molded durably assume compressed dimensions caused technique. can be moved so apply energy large section anatomic In aspect, location electrodes determined impedance monitoring. Also, temperature sensors are averaged determine temperature.
