Abstract
An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body has a programmable signal generator that can generate the signals based on stored signal parameters without any intervention from a processor that controls the overall operation of the IPG. While the signal generator is generating the signals the processor can be in a standby mode to substantially save battery power.
Claims20
A spinal cord stimulation system comprising:
- an implantable pulse generator;
- a plurality of electrodes for delivering electrical pulses to a patient;
- a plurality of leads connecting the plurality of electrodes to the implantable pulse generator;
- and
- an application-specific integrated circuit (ASIC), the ASIC further comprising:
- a control register bank;
- a digital controller electronically coupled to the control register bank;
- a current digital to analog converter block electronically coupled to the digital controller;
- and
- an electrode driver block electronically coupled to the current digital to analog converter block,
- wherein the plurality of electrodes comprise at least one channel and receive current from the electrode driver block, and
- wherein the at least one channel is active depending on channel arbitration performed by the digital controller.
An application-specific integrated circuit (ASIC) for use in a spinal cord stimulation system, the ASIC further comprising:
- a communications interface configured to electronically communicate with a microcontroller;
- a control register bank;
- a digital controller electronically coupled to the control register bank;
- a current digital to analog converter block electronically coupled to the digital controller;
- and
- an electrode driver block electronically coupled to the current digital to analog converter block, and
- wherein at least one channel is active depending on channel arbitration performed by the digital controller.
