DEVICE AND METHOD FOR ELECTROSURGERY |
摘要 |
A method and apparatus are disclosed for improving accuracy of placement of a cannula during delivery of electrical energy to neural structures. The apparatus includes a cannula operable to deliver electrical current where a portion of the cannula is electrically insulated and a portion of the cannula is exposed and electrically conductive. The cannula further includes a radiopaque marker located to differentiate the electrically insulated region from the electrically exposed region by allowing it to be more clearly delineated using fluoroscopy or other radiographic imaging techniques. The cannula may be used to treat pain by delivering energy to a neural structure.
