Spinal cord stimulator system
First Claim
1. A method of providing electrical pulse therapy to patient via an implantable spinal cord stimulation device, comprising the steps of:
- providing an implantable pulse generator with a microcontroller and an application specific integrated circuit (ASIC), wherein the ASIC comprises a digital circuit and an analog circuit;
receiving one or more commands sent by an external remote at a transceiver within the implantable pulse generator and transmitting the one or more commands to the microcontroller;
receiving, by the ASIC data representing the one more commands;
performing, by the digital circuit of the ASIC, signal processing in accordance with the one or more commands to generate one or more corresponding signals for the electrical pulse therapy, wherein the corresponding signals include timing information for the electrical pulse therapy; and
delivering the one or more signals for the electrical pulse therapy to an epidural space of a patient as directed by the analog circuit of the ASIC.

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 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.
