IMPLANTABLE PULSE GENERATOR THAT GENERATES SPINAL CORD STIMULATION SIGNALS FOR A HUMAN BODY

摘要

An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body includes a timing generator and high frequency generator. The timing generator generates timing signals that represent stimulation signals for multiple channels. The high frequency generator determines whether to modulate the timing signals and modulates them at a burst frequency according to stored burst parameters if the decision is yes. As such, the IPG provides the ability to generate both the low frequency and high frequency stimulation signals in different channels according to user programming.

1. An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body, comprising:
control registers storing stimulation signal parameters for a plurality of channels with each channel capable of being associated with at least two electrodes among a plurality of electrodes, each channel representing a stimulation signal pattern of the associated electrodes, the signal parameters including burst parameters; a timing generator adapted to generate timing signals representing stimulation signals for the plurality of channels according to the stored signal parameters; a high frequency generator adapted to determine whether to modulate the timing signals received from the timing generator and modulate the received timing signals at a burst frequency according to the stored burst parameters.
