An implantable electrode paddle for use in a neurostimulation system may include a dorsally-projecting lead that allows all of the edges of the electrode paddle to be situated near a vertebral body for stimulation of neural structures. Embodiments may include one or more flanges for cooperating with a vertebral body and thereby stabilizing the electrode paddle. Embodiments of the present invention may also include features to allow an electrode paddle to be divided during surgery. Embodiments of the present invention may also include an electrode paddle having a plurality of paddle sections, wherein at least one of the paddle sections comprises a plurality of asymmetrically configured contacts. Embodiments of the invention include a method of assembling a neurostimulation system and a method of implanting an implantable system in a body, wherein the implantable system includes an electrode paddle that may be divided into a plurality of paddle sections.

Electrode paddle for neurostimulation

A method of distinguishing nociceptive pain from neuropathic pain includes providing a series of questions for answering by the patient. Each of the answers by the patient are given a numerical value within a nociceptive pain category and a neuropathic pain category. The values within the two categories are then summed, with the resultants potentially modified using a series of one or more equations. The ratio of the neuropathic pain to the nociceptive pain is then calculated. The ratio provides a value for the physician to diagnose the patient as suffering from nociceptive pain, neuropathic pain, or both nociceptive pain and neuropathic pain. Embodiments of the present invention include a system for assisting a physician to identify whether a patient's pain is nociceptive pain or neuropathic pain.

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.

According to one embodiment, a system for neurological stimulation of peripheral nerve fibers to treat low back pain is provided. The system includes stimulation electrodes adapted to be implanted in tissue proximate a network of peripheral nerve fibers located in and innervating a painful region of the low back area and to deliver electrical stimulation pulses to the network of peripheral nerve fibers located in and innervating the painful region of the low back area. The system also includes a stimulation source adapted for implantation into the person's body and operable to generate electrical stimulation pulses for transmission to the electrodes for delivery to the network of peripheral nerve fibers located in and innervating the painful region of the low back area to relieve pain in the painful region of the low back area.

An implantable spool is used for spooling the excess wiring associated with a lead that extends between at least one electrode and a pulse generator of an electrical stimulation implant system. The present invention also has application to providing a spool for coiling tubing of an implantable drug delivery system. Embodiments of the invention include a method of implanting an implantable system in a body, wherein the implantable system includes a source unit and an elongated member. A method of assembling an implantable system is also described.
