Abstract: New waveforms for use in an implantable pulse generator or external trial stimulator are disclosed which mimic actively-driven biphasic pulses, and which are particularly useful for issuing low frequencies pulses. The waveforms comprise at each electrode interleaved first and second pulses. Each first pulse comprises a first monophasic pulse and a first passive charge recovery period. Each second pulse comprises a second monophasic pulse with a polarity opposite the first monophasic pulse and a second passive charge recovery period. Preferably, the amplitudes and pulse widths of the first and second monophasic pulses are equal, or at least charge balanced at each electrode. The first and second monophasic pulses mimic the functionality of a symmetric biphasic pulse, with the first monophasic pulse mimicking the functionality of the biphasic pulse's first phase, and the with the second monophasic pulse mimicking the functionality of the biphasic pulse's second phase.

Abstract: A system may include a neuromodulator and a processing system. The neuromodulator may be configured to be programmed with a set of more than one program to deliver neuromodulation. The processing system may be configured to: receive sensed data indicative of activity, motion and/or posture of a patient; analyze the activity, motion and/or posture of the patient; and perform a process, based on the analyzed activity, motion and/or posture, for switching from one program in the set of more than one program to another program from the set of more than one program. The process may include automatically implementing the other program from the set of more than one program or suggesting to switch to the other program from the set of more than one program.

Abstract: Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which a stimulation location in an electrode array is determined. Preferably, the supra-perception stimulation comprises a bipole formed using actively-driven symmetric biphasic waveforms at active ones of the electrodes in the array. After determining the location, a perception threshold for the bipole at the location is determined and stored, and an amplitude of the stimulation is reduced below the perception threshold to provide a sub-perception stimulation bipole. The determined perception threshold may be transmitted to the patient's remote controller, where it is used to limit amplitude adjustments to the sub-perception bipole by the patient.

Abstract: Systems and methods for optimizing neuromodulation field design for pain therapy are discussed. An exemplary neuromodulation system includes an electrostimulator to stimulate a target neural element with first neuromodulation energy, a data receiver to receive pain data including pain sites experiencing pain, and to physiological data including body sites responsive to the first neuromodulation energy. A processor circuit can determine a pain distribution and a response distribution over respective sets of dermatomal compartments, generate a pain targeting metric (PTM) using the pain distribution and the response distribution, and determine an optimal stimulation setting for neuromodulation pain therapy based on the pain targeting metric.
