First Claim
Patent Images
1. A system for spinal cord stimulation comprising:
- a plurality of stimulation electrodes, wherein each of the stimulation electrodes are used to provide electrical pulse therapy to a spinal cord of a patient;
a plurality of leads, wherein each of the plurality of leads extends to one of the stimulation electrodes;
a lead anchor implantable into the patient, the lead anchor configured to lock one of the plurality of leads to tissue of the patient to prevent migration of a distal tip of the one of the plurality of leads, wherein the lead anchor includes a locking set screw;
an implantable pulse generator configured to be implantable into the patient and connectable to the plurality of leads, wherein the implantable pulse generator is configured to generate signals to transmit to the plurality of stimulation electrodes; and
a trial generator configured to be temporarily connectable to the plurality of leads to determine the signals generated by the implantable pulse generatorwherein the lead anchor includes a blocking set screw, positioned in the lead anchor, to prevent the locking set screw from backing out.

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.
