Secured and self contained spinal cord stimulator leads and catheters

Abstract

A stimulator lead is herein disclosed. The stimulator lead includes a proximal portion that is configured for placement external the epidural space through a first opening, wherein said proximal portion is operatively connected to an IPG unit, a distal portion that is configured for placement external the epidural space through a second opening, and a third portion between the proximal and distal portions that is configured for percutaneous placement in an epidural space, wherein said middle portion includes at least one stimulator electrode for placement adjacent to target dura.

1 - 20 . (canceled) 
     
     
         21 . A spinal cord stimulator comprising:
 a proximal end and a distal end, wherein each end comprises an anchoring device adapted to anchor the spinal cord stimulator within the epidural space;   a circuit board;   a battery;   a pulse generating unit comprising one or more electrodes, wherein the pulse generating unit is operably connected to the battery and the circuit board, and is configured to deliver an electrical pulse through the one or more electrodes;   wherein the spinal cord stimulator is configured to be implanted entirely within the epidural space of a human.   
     
     
         22 . The spinal cord stimulator of  claim 21 , wherein the circuit board is adapted to be programmed wirelessly. 
     
     
         23 . The spinal cord stimulator of  claim 21 , wherein the battery is adapted for wireless charging. 
     
     
         24 . The spinal cord stimulator of  claim 21 , wherein the pulse generating unit comprises a single electrode wire. 
     
     
         25 . The spinal cord stimulator of  claim 21 , wherein the pulse generating unit comprises a plurality of electrodes. 
     
     
         26 . The spinal cord stimulator of  claim 21 , wherein the pulse generating unit is configured to control at least one of a frequency and an amplitude of the electrical pulse. 
     
     
         27 . The spinal cord stimulator of  claim 21 , wherein the pulse generating unit is configured to control a frequency and an amplitude of the electrical pulse. 
     
     
         28 . The spinal cord stimulator of  claim 21 , wherein the pulse generating unit is configured to independently control a plurality of electrodes. 
     
     
         29 . The spinal cord stimulator of  claim 28 , wherein the pulse generating unit is configured to control at least one of a frequency and an amplitude of the electrical pulse at each of the independently-controlled electrode. 
     
     
         30 . The spinal cord stimulator of  claim 28 , wherein the pulse generating unit is configured to control a frequency and an amplitude of the electrical pulse at each of the independently-controlled electrodes. 
     
     
         31 . The spinal cord stimulator of  claim 21 , wherein the anchoring device comprises a suture, a button, or a wire.
