Systems and methods to place one or more leads in tissue for providing functional and/or therapeutic stimulation

Abstract

Systems and methods make possible the placement of one or more electrode leads in a tissue region for providing functional and/or therapeutic stimulation to tissue. The systems and methods are adapted to provide the relief of pain.

1 . A method comprising:
 percutaneously inserting and placing an electrode at a targeted tissue region, the electrode includes a coiled lead having an anchoring member generally preventing migration of the electrode, wherein the targeted tissue region is in proximity to a peripheral nerve innervating a painful region and the targeted tissue region is spaced from the painful region,   providing percutaneous neurostimulation to the electrode, activating the peripheral nerve via the neurostimulation, and   as a result of the neurostimulation, reducing post-amputation pain in the painful region.   
     
     
         2 . The method according to  claim 1 , wherein the targeted tissue region comprises a brachial plexus. 
     
     
         3 . The method according to  claim 2 , wherein the targeted tissue region further comprises a region of adipose tissue on, in, or near the brachial plexus. 
     
     
         4 . The method according to  claim 1 , wherein the peripheral nerve comprises at least one nerve group consisting of: a brachial plexus, a sciatic nerve, and a femoral nerve. 
     
     
         5 . The method according to  claim 1 , wherein the peripheral nerve comprises at least one nerve in the group consist of: a sciatic nerve and a femoral nerve. 
     
     
         6 . The method according to  claim 1 , wherein the post-amputation pain comprises residual limb pain. 
     
     
         7 . The method according to  claim 1 , wherein the post-amputation pain comprises phantom limb pain. 
     
     
         8 . The method according to  claim 7 , wherein the post-amputation pain further comprises residual limb pain. 
     
     
         9 . A system comprising:
 a single percuanteous lead having at least one electrode placed in vivo on, in, or near a brachial plexus, the lead being a coiled wire and having an anchoring member generally preventing migration of the lead, wherein the electrode is outside of a region of post-amputation pain, and   an ex vivo stimulator percutaneously delivering neurostimulation through the lead and electrode to stimulate a peripheral nerve effecting a reduction of the post-amputation pain.
