Peripheral nerve field stimulator curved subcutaneous introducer needle with wing attachment specification

Abstract

An apparatus for use in peripheral nerve field stimulation (PNFS) whereby a plurality of curved introducer needles, of varying curvatures, are provided to permit the physician to best locate the region of oligodendrocytes that contain the A Beta fibers by matching the lumbar lordosis. A wing device is also provided that is attachable to the hub of the curved needle introducer which gives the physician better ability to maneuver the needle during insertion as well as permitting tenting of the skin. The invention benefits a large number of painful disorders arising from pathology in the cervical, thoracic, and lumbar spine. In addition, this invention can also help a large number of other conditions including but not limited to failed back surgery syndrome/post-laminectomy pain, occipital/suboccipital headaches, scar pain, post herpetic neuralgia pain, mononeuritis multiplex, and pain following joint surgery (e.g., knee, hip, shoulder).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 464,470, filed May 12, 2009, which claims the benefit of U.S. Provisional Application No. 61 / 052,464, filed May 12, 2008, which is incorporated herein by reference.FIELD OF INVENTION[0002]The current invention relates to surgical methods, and more particularly, to a neuromodulation device.BACKGROUND[0003]Peripheral Nerve Field Stimulation (PNFS) is a rapidly growing area of neuromodulation that has shown significant promise in treating patients with cervical, thoracic, and lumbar pain. This procedure, however, has relied on using electrical leads designed for stimulation of the dorsal column of the spinal cord despite the reputed target neural element being a vastly different structure. In peripheral nerve field stimulation, the neural elements that are targeted for depolarization are the terminal dendrocytes located in the subcutaneous region of the patient.[0004]T...

AI Technical Summary

Benefits of technology

[0008]An apparatus for supporting peripheral nerve field stimulation (PNFS) of living being tissue is disclosed. The apparatus comprises: an introducer having a curved portion; a stylet having a curved portion that is similar to the curved portion of the introducer so that the stylet can be inserted within the introducer to form an introducer needle assembly; and wherein the introducer needle assembly provides a pas...

Problems solved by technology

However, achieving the proper placement of the distal end of the Touhy epidural needle for use during PNFS is very difficult for a number of reasons.

In addition, the small surface area of the proximal end of the Touhy epidural needle does not give the physician the required grippi...
