Abstract: 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.

Abstract: The present inventions provide for 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. More specifically, one or more embodiments of the electrodes of the present inventions 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 embodiments of the present inventions are particularly well suited for perineurial implantation. Embodiments of the present inventions include methods of use associated with the electrodes.

Abstract: The present disclosure provides a modular neurostimulator system. The system includes a stage one implant that can be externally powered and controlled. The stage one implant is made of one or more leads as well as a passive receiver and an external controlling and powering device. The receiver and the external device can be utilized either as a long-term trial system, or as a permanent system. Since the receiver and the external device can have limited costs and features, they are suited for a long-term trial without risk of infection and excessive upfront cost. The system may also include a stage two implant that includes an implantable power supply and/or control elements connectable to one or more previously implanted stage one implants. A method of treatment for limb peripheral nerves using such a modular system is also disclosed.
