1. A tethered electrode lead comprising:
- a coupling member having a first length; and
a kit comprising an electrode lead having an electrode and a distal end including an opening, and an anchor having an eyelet, the anchor configured to be secured to an anatomical structure,wherein a first end of the coupling member is coupled to the opening in the electrode lead and a second end of the coupling member is configured to pass through the eyelet of the anchor and the coupling member is adjustable within the patient to a second length, different from the first length, and wherein the coupling member is configured to secure the electrode lead in an implanted position at a desired anatomical site within the patient such that the opening of the electrode lead is spaced apart from the eyelet of the anchor by the second length.

Abstract
Apparatus and methods for tethering an electrode lead to an anatomical structure within a patient using a coupling member are provided. An anchor configured to be secured to the anatomical structure and an electrode lead suitable for neuromuscular stimulation of spinal muscles and/or nerves innervating one or more muscles that contribute to spine stability may be used. The electrode lead is configured to be coupled to the anchor via the coupling member by securing a first end of the coupling member to the electrode lead and securing a second end of the coupling member to an eyelet of the anchor to place the electrode lead at a desired anatomical site within the patient.
