Abstract
The disclosure is directed to a method and tool for implanting a stimulation lead or other medical device adjacent a pudendal nerve. The tool includes a shaped needle that enters a patient and passes through an obturator foramen passage in a pelvis. A physician places a tip of the tool at the pudendal nerve and performs test stimulation to confirm an effective stimulation location. A shape memory cannula initially covering the needle remains at the pudendal nerve when the physician removes the tool. The cannula deforms to follow the curve of the pudendal nerve once the needle is removed, and a lead is inserted into the cannula and secured at the pudendal nerve placement site. This method may provide an easier and more consistent procedure for implanting the stimulation lead near the pudendal nerve.
