Abstract
A system of implanting electrode leads for restoring muscle function to the lumbar spine to treat low back pain is provided. The system provides efficient implantation of the leads, including the ability to verify deployment of anchoring mechanisms on the lead using an impedance assessment, such that the implanted lead may be secured within the patient and used to restore muscle function of local segmental muscles associated with the lumbar spine stabilization system.

15. A kit for implanting an electrode lead in a system for restoring muscle function to the lumbar spine, the kit comprising:
-
a sheath configured for insertion in a lower back of a patient, the sheath having a lumen extending therethrough; a needle electrode having a distal end configured to be positioned in or adjacent to tissue associated with control of the lumbar spine through the lumen, the needle electrode further configured to stimulate the tissue to permit verification of needle electrode positioning; and a lead having an electrode at a distal end of the lead, the lead configured for implantation through the lumen to position the electrode in or adjacent to the tissue associated with control of the lumbar spine. - View Dependent Claims (16, 17, 21, 22, 23, 24, 25, 26, 27, 28)

18. A method of implanting an electrode lead, the method comprising:
-
inserting a needle electrode disposed within a lumen of a sheath into a patient such that a distal end of the needle electrode is positioned in or adjacent to tissue associated with control of the lumbar spine; stimulating the tissue with the needle electrode; verifying placement of the distal end of the needle electrode at the tissue; removing the needle electrode from the sheath; inserting an electrode lead through the lumen of the sheath such that an electrode disposed on the lead is implanted in or adjacent to the tissue associated with control of the lumbar spine; and removing the sheath. - View Dependent Claims (19, 20, 29, 30, 31, 32, 33, 34)
