Systems and methods to place one or more leads in muscle for providing electrical stimulation to treat pain
First Claim
1. A method to alleviate pain, the method comprising:
- identifying a tissue region where pain is perceived including skeletal muscle innervated by a peripheral nerve and including a motor point, wherein identifying the tissue region includes locating the motor point by percutaneously placing a locating lead and applying the therapeutic electrical stimulation to the locating lead and adjusting the position of the locating lead until a muscle twitch is observed in the skeletal muscle and the motor point is located without any verbal feedback from the patient;
placing at least one intramuscular lead having at least one electrode within the skeletal muscle in electrical proximity, the motor point, andapplying therapeutic electrical stimulation to the at least one electrode according to predefined therapeutic electrical stimulation parameters to affect afferent and/or efferent nerve stimulation within the skeletal muscle and to provide the therapeutic electrical stimulation to the motor point to alleviate pain without any functional nerve stimulation involving the skeletal muscle.

Abstract
Systems and methods are adapted to provide the relief of pain. The systems and methods make possible the percutaneous placement of one or more intramuscular leads, without the need for fluoroscopy, for providing electrical stimulation to activate a motor point innervating the muscle, to provide the therapeutic relief of pain. The one or more intramuscular leads may be placed in muscle(s) to resist migration. The target nerves and their motor points innervate the muscles in which the one or more leads are placed. The systems and methods can include a two-stage solution. The first stage may include temporary systems and methods, including the use of an external pulse generator. The second stage may include more permanent systems and methods, including the use of an implanted pulse generator.

4. A method comprising:
-
placing a first lead in electrical proximity to a first motor point of a first muscle, placing a second lead in electrical proximity to a second motor point of a second muscle, placing a third lead in electrical proximity to a point generally in-between the first lead in electrical proximity to the first motor point of the first muscle and the second lead in electrical proximity to the second motor point of the second muscle, and providing electrical stimulation to the third lead to activate the motor point of the first muscle and the motor point of the second muscle. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
