More Information
Summary:A method and apparatus are disclosed for improving accuracy of placement of a cannula during delivery of electrical energy proximate to bodily tissue, e.g. neural structures. The apparatus optionally 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 to identify a specific portion of the cannula, for example 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 radiopaque marker is optionally tapered in order to reduce the force required to insert a cannula comprising a radiopaque marker into the patient's body.
