Multi-programmable trial stimulator
First Claim
1. A stimulator system for generating electrical pulses for application to tissue of a patent, the system comprising:
- a processor for controlling the system under control of executable instructions;
stimulation source circuitry for generating electrical pulses for application to tissue of the patient; and
capacitors coupled between the stimulation source circuitry and outputs of the stimulator system;
wherein the processor is programmed to control the stimulation source circuitry to provide stimulation according to a multi-stimulation set program that defines multiple pulses to be interleaved according to respective sets of pulse parameters, wherein a multi-stimulation set program defines a program pulse frequency;
wherein the processor is further programmed to selectively apply active discharge of capacitors according to the program pulse frequency of a respective multi-stimulation set program by selecting from (i) a first mode of operation that employs an active discharge pulse amplitude that is a first fraction of a preceding stimulation pulse for a program pulse frequency above a first frequency threshold and below a second frequency threshold, and (ii) a second mode of operation that employs an active discharge pulse amplitude that is a second fraction of a preceding stimulation pulse for a program pulse frequency above the second frequency threshold, wherein the second fraction is less than the first fraction.

Abstract
Disclosed are systems and methods which provide trial stimulators suited for use interoperatively and during patient trial. Trial stimulator embodiments provide a patient interface and/or clinician interface which appears and functions substantially the same as an interface of a pulse generator controller which will be used after a trial period. A compliance monitor feature may be provided to facilitate verifying the proper use of the trial stimulator during a trial period. A diagnostic feature may be provided to facilitate verifying proper operation of various aspects of a trial stimulator, such as electrode impedance analysis. Trial stimulators of embodiments provide stimulation to a plurality of tissues and/or areas of the body, such as spinal cord stimulation, deep brain stimulation, etcetera. Embodiments provide for multi-electrode stimulation and multi-stimulation programs. Embodiments are configured to provide active discharge of stimulation pulses as well as to utilize constant current sources in providing the stimulation pulses.
