20230347153 · 2023-11-02 ·

Systems and methods for the efficient use of an implantable pulse generator (IPG) battery are disclosed. A representative system for adjusting an electrical signal of an IPG associated with delivering therapy to a patient comprises a computer readable medium having instructions that cause the IPG to deliver a supply voltage at a first value, adjust the supply voltage from the first value until a threshold break occurs, and, based at least in part of the threshold break, increase the supply voltage from the second value to a third value. As therapy is delivered to the patient, the system iteratively adjusts the supply voltage to approach and reflect a variable minimum voltage needed to provide the requested current to the IPG.

The techniques of the disclosure describe example medical devices, systems, and methods for interleaving a plurality of low-frequency electrical stimulation pulse trains delivered by a plurality of sets of electrodes of an implantable medical device (IMD) to effectively deliver a combined high-frequency electrical pulse train to a target tissue area. In one example, each set of the plurality of sets of electrodes has a unique anode and cathode. In another example, a clinician adjusts the size or shape of the target tissue area receiving the combined high-frequency electrical pulse train by selecting different combinations of the plurality of sets of electrodes.

Management of Compliance Voltage for a Stimulator Device

A compliance voltage management algorithm is disclosed for managing the compliance voltage, VH, that powers the DAC circuitry in a stimulator device. A user can use a user interface associated with an external programming device to define a time-varying stimulation waveform to be programmed into the stimulator device. The algorithm analyzes the prescribed waveform and determines a number of groups of pulses that will be treated similarly from a VH management standpoint. Optimal compliance voltages are determined for each group, as are the rise and fall rates at which VH is able to change at transitions between groups. These rise or fall rates in VH are then used to set when the compliance voltage should increase or decrease. For example, the algorithm will automatically set VH to start rising in advance of a transition so that it is at the proper higher value when the transition occurs.
