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.

7. A system adapted for spinal cord stimulation (SCS) of a patient, the system comprising:
-
a plurality of stimulation leads with each stimulation lead comprising a plurality of electrodes adapted for implantation within the epidural space of the patient; a pulse generator for generating stimulation pulses for delivery to tissue of the patient through electrodes of the plurality of stimulation leads, wherein (i) the pulse generator is adapted to provide thirty-two (32) independent output channels, and (ii) the pulse generator comprises a plurality of ports with each port adapted for electrical connection to a distinct subset of the thirty-two independent output channels; and at least one splitter adapter, wherein the at least one splitter adapted to connect with one of the plurality of ports and to provide electrical connection to at least two of the plurality of stimulation leads, wherein each port comprises a greater number of output channels than a number of electrodes disposed on each of the at least two of the plurality of stimulation leads; a programmer device for communication with the pulse generator, wherein the programmer device is adapted to receive input data from a user that identifies specific lead types of the at least two of the plurality of stimulation leads selected for coupling to the at least one splitter adapter. - View Dependent Claims (8, 9, 10, 11, 12)
