Surgically implantable electrodes
First Claim
1. An implantable electrode for electrically stimulating tissues, comprising:
- (a) a paddle configured to be implanted subcutaneously comprising;
(i) a forward portion located along a first end of the paddle, the forward portion including at least one electrical contact disposed within the forward portion substantially toward a ventral surface of the paddle; and
(ii) a back portion connected to the forward portion and located along a second end of the paddle, wherein the back portion is deformable from the forward portion, and wherein the back portion is devoid of one or more electrical contacts;
(b) at least one contact wire interconnected at a first end to the at least one electrical contact, the at least one contact wire extending through at least a portion of the forward portion of the paddle, wherein the at least one contact wire is interconnected at a second end to a lead extending from a lead connection located on a dorsal surface of the paddle between the forward portion and the back portion, wherein the lead is adapted to be interconnected to a power source; and
(c) a notch that extends to a depth of approximately one-half of a thickness of the paddle located on the ventral surface of the paddle that is within and transversely oriented to a longitudinal axis of the paddle;
wherein the at least one contact wire provides electrical continuity between the at least one electrical contact and the lead; and
wherein the lead provides electrical continuity between the at least one contact wire and the power source.

Abstract
Paddle lead electrodes that are capable of performing peripheral nerve stimulation, thereby modulating, controlling and/or reducing neuropathic pain in a patient, that are also surgically implantable, and that will remain fixed in place at the site of implantation when in use are provided. More specifically, one or more embodiments of the electrodes are capable of being surgically implanted underneath a sheath of protective connective tissue that covers electrically excitable tissues and are adapted to electrically stimulate those tissues. Electrodes contemplated by some embodiments are particularly well suited for perineurial implantation. Some embodiments include methods of use associated with the electrodes.

2. An implantable electrode for electrically stimulating a tissue, the implantable electrode adapted to be interconnected to a power source using a lead, the implantable electrode comprising:
-
(a) a paddle configured to be implanted subcutaneously comprising; (i) a forward portion located along a first end of the paddle, the forward portion including at least one electrical contact disposed within the forward portion along a ventral surface of the paddle; and (ii) a back portion connected to the forward portion, the back portion being at least one of deformable and extendable from the forward portion, wherein the back portion is devoid of one or more electrical contacts; (b) at least one contact wire interconnected to the at least one electrical contact and extending along at least a portion of the forward portion of the paddle, the at least one contact wire providing electrical continuity between the at least one electrical contact and the lead; (c) a lead connection located along a dorsal surface of the paddle, wherein the lead connection directionally transitions the at least one contact wire from an orientation substantially planar to the paddle to the lead, the lead situated in an orientation transverse to the dorsal surface of the paddle, and wherein the lead connection is located longitudinally along the dorsal surface between the forward portion and the back portion; and (d) a notch that extends to a depth of approximately one-half of a thickness of the paddle located on the ventral surface of the paddle that is within the paddle and transversely oriented to a longitudinal axis of the paddle.

3. An implantable assembly for treating neuropathy, comprising:
-
(a) an implantable electrode configured to be implanted subcutaneously, comprising; (i) a forward portion located along a first end of the implantable electrode, the forward portion including a plurality of electrical contacts disposed within the forward portion toward a ventral surface of the implantable electrode; and (ii) a back portion connected to the forward portion and located along a second end of the implantable electrode, wherein the back portion is at least one of selectively adjustable and deformable relative to the forward portion, wherein the back portion is devoid of one or more electrical contacts; wherein at least one of the forward portion or the back portion comprise a notch extending to a depth of approximately one-half of a thickness of the electrode and located on the ventral surface of the implantable electrode and transversely oriented to a longitudinal axis of the implantable electrode; (b) a lead extending from a lead connection located on a dorsal surface of the implantable electrode substantially between the forward portion and the back portion; (c) means for providing electrical continuity between the plurality of electrical contacts and the lead; and (d) a power source interconnected to the lead at a location spaced apart from the implantable electrode. - View Dependent Claims (4, 5)
