Spinal cord stimulator system
First Claim
1. A spinal cord stimulation device for use in delivering therapy to an epidural space, said spinal cord stimulation device comprising:
- an implantable pulse generator sized and configured to be subcutaneously implanted in a patient comprising a microcontroller, an application specific integrated circuit (ASIC) and an RF antenna, at least one battery, a charging coil to accommodate charging of the at least one battery, and a casing, wherein the RF antenna and microcontroller are operably coupled thus allowing signals received by the RF antenna to be passed to the microcontroller and the ASIC is configured to receive commands from the microcontroller which sets a plurality of stimulation parameters thereby configuring the ASIC to generate a stimulation signal without further microcontroller involvement;
a lead extending from the implantable pulse generator to carry the stimulation signal to an epidural space;
an electrode attached to the lead and configured to receive the stimulation signal and deliver the therapy into the epidural space; and
a clinician programmer application provided on a computing device, the clinician programmer application configured to communicate with the implantable pulse generator through an RF communications link which communicates with the RF antenna, the clinician programmer application further capable of sending signals which initiate the setting the plurality of stimulation parameters for use in generating stimulation signals.

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 outsource, and [PG 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.
