| 摘要 |
Disclosed are methods and devices for occluding the lumen of a hollow organ by delivering radiofrequency energy to the inner wall of a hollow organ. The disclosure includes radiofrequency electrodes that expand, in a deployed condition, to contact the walls of the organ. In some embodiments, the electrodes substantially conform to the inner wall to enhance therapeutic contact. Methods are also disclosed for using these electrodes to totally or partially occlude a lumen, or remove or reduce a total or partial occlusion of a lumen.
