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);
receiving one or more commands sent by an external remote at a transceiver and transmitting the one or more commands to the microcontroller;
receiving, by the ASIC, data representing the one more commands;
performing, by the ASIC, signal processing in accordance with the one or more commands to generate one or more signals for the electrical pulse therapy; and
generating a high speed burst pulse and combining the high speed burst pulse with a stimulation pulse to generate a bursted bi-phasic pulse train, and wherein delivering the one or more signals for electrical pulse therapy comprises delivering the bursted bi-phasic pulse trainwherein the bi-phasic pulse train includes timing information and does not contain amplitude information,delivering the one or more signals for the electrical pulse therapy to electrodes positioned in an epidural space of a patient.

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.
