Patent ID: 6895280

Claim:
A spinal cord stimulation system comprising: a multi-channel implantable pulse generator (IPG) having a replenishable power source, the IPG having a housing which contains IPG processing circuitry; an implantable electrode array detachably connected to the IPG, the electrode array having a multiplicity of n electrodes (En) thereon; a multiplicity of m stimulation channels provided by the IPG, wherein each stimulation channel is independently programmable with different stimulation parameters, wherein m is equal to or less than n, and m is 2 or greater; and means for non-invasively charging the replenishable power source, wherein the different stimulation parameters include; pulsewidth, stimulation amplitude, repetition rate or pulses per second (pps), and an electrode configuration that may be either monopolar or bipolar; wherein the IPG comprises processing circuitry including: a control logic circuit, a timer logic circuit, a microcontroller circuit, and a memory circuit coupled to the microcontroller circuit; and wherein the control logic, timer logic and microcontroller circuits are responsive to programming signals stored in the memory circuit to generate stimulation pulses having a specified amplitude, pulsewidth and repetition rate (pps).
