Spinal cord stimulator system
First Claim
1. A spinal cord stimulation device for delivering electrical stimulation therapy to a spinal cord, said device comprising:
- an implantable pulse generator comprising;
a circuit board housed in a casing, the circuit board including an application specific integrated circuit (ASIC) and a microcontroller, wherein the ASIC is configured to receive digital data from the microcontroller, wherein the ASIC is configured to perform all of the signal processing necessary for electrical stimulation and to generate electrical stimulation pulses based on said signal processing, wherein the ASIC is configured to handle all power management of the implantable pulse generator, and wherein the microcontroller is configured to remain powered down until the ASIC sends a signal to the microcontroller to power up; and
a plurality of electrodes configured to be wired to the implantable pulse generator, wherein the plurality of electrodes are configured to send the electrical stimulation pulses to the spinal cord.

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 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.
