Patent attributes
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.
