Spinal cord stimulator system
First Claim
1. An implantable pulse generator configured to produce electrical stimulation pulses to the spinal cord, said implantable pulse generator comprising:
- a lead contact assembly configured to deliver the electrical stimulation pulses to a plurality of stimulation electrodes, wherein each of the plurality of stimulation electrodes provide stimulation to an epidural space of a patient, wherein each of the plurality of stimulation electrodes are grouped into one or more channels, and wherein each channel comprises at least two stimulation electrodes; and
a circuit board comprising an application specific integrated circuit (ASIC) and a microcontroller, the microcontroller in communication with the application specific integrated circuit;
wherein the application specific integrated circuit comprises arbitration control configured to analyze timing generator envelope signals and permits only one signal to be active at a time in order to provide one active channel among the one or more channels, andwherein the application specific integrated circuit receives a first clock from the microcontroller for internal digital circuitry of the ASIC and receives a second clock from which the electrical stimulation pulses are based.

Abstract
Spinal cord stimulation (SCS) system having a recharging system with self alignment, a system for mapping current fields using a completely wireless system, multiple independent electrode stimulation outsources, and IPG control through software on Smartphone/mobile device and tablet hardware during trial and permanent implants. SCS system can include multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) providing concurrent, but unique stimulation fields. SCS system can include a replenishable power source, rechargeable using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery, can charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. A bi-directional telemetry link informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in current IPG allows electrode impedance measurements to be made.
