Removable intramuscular electrode
First Claim
1. A method of inserting and removing an electrode in target tissue in a patient for short term or temporary stimulation of the target tissue, the method comprising:
- inserting a tissue-piercing guide into and through the target tissue;
pulling an electrode connected to a proximal end of the tissue-piercing guide into the target tissue, the electrode being connected to the tissue-piercing guide by a tether extending distally from the electrode;
extending an electrical lead and the tether proximally from the electrode to an electrical connection location wherein the electrical lead surrounds at least a portion of the tether;
applying electrical stimulation to the target tissue through the electrode after the step of extending the electrical lead; and
removing the electrode from the target tissue, the removing step comprising separating the electrical lead and the tether prior to pulling proximally on the electrical lead and pulling proximally on the tether.

Abstract
An implantable medical electrode system for intramuscular use that is readily removable is provided, as well as methods for its use. The system includes an electrode, an electrical lead mechanically and electrically connected to the electrode and extending proximally, and a tether bonded to the electrode and extending proximally. A conductor with an insulated portion enwraps the electrical lead; an uninsulated portion enwraps the electrode. Some embodiments may include a tissue-piercing guide such as a needle. In some embodiments, the electrode includes a barb, although in some of these embodiments the tether does not extend through the barb. The method of using the system includes inserting the through a target tissue, pulling the electrode with the needle into the target tissue, and extending the electrical lead and tether proximally to an electrical connection. Methods are further provided for removing the electrode which take advantage of structural features of the system.
