Abstract
A stimulation device that includes a housing, a neuro lead configured to be coupled to the housing and to be located proximate to a neurostimulation site of interest, a neuro pulse generator, in the housing, configured to generate multi-polar neuro modulation (NM) pulses for delivery by the lead to the neuromodulation site of interest and the neuro pulse generator generating the NM pulses utilizing a waveform, with the frequency components of the ICMD compatible waveform in a range of 0 to 225 Hz having substantially limited NM energy content to avoid interference with sensing operation of the ICMD. A method for managing a neuromodulation (NM) device to avoid interference with an implantable medical device (ICMD) providing an ICMD having electrodes configured based on ICMD sensing parameters that define an ICMD sensing frequency range, providing an NM device having NM electrodes to be located proximate a region of interest, the NM electrodes delivering NM pulses based on NM pulse parameters, setting at least one NM pulse parameter in a manner that limits an amount of NM energy content that propagates beyond an active area surrounding the site of interest within the ICMD sensing frequency range.
