    Abstract: An implantable medical device includes a low-power circuit and a multi-cell power source. The cells of the power source are coupled in a parallel configuration. The implantable medical device includes both a low power circuit that is selectively coupled between the first and second cells and a high power output circuit that is directly coupled to the first and second cells in a parallel configuration. An isolation circuit is coupled to the first cell, the second cell and the low power circuit to maintain a current isolation between the first cell and the second cell at least during delivery currents having a large magnitude that are delivered to the high power output circuit.

    Abstract: Recent advancements in power electronics technology have provided opportunities for enhancements to implantable medical device circuits. The enhancements have contributed to increasing circuit miniaturization and increased efficiency in the operation of the implantable medical devices. Stimulation therapy waveforms generated by the circuits include a stepped leading-edge that may be shaped having a varying slope and varying amplitudes associated with each of the segments of the slope. A charging circuit having a single primary transformer winding and a single secondary transformer winding that is coupled to a plurality of capacitors is utilized to generate the therapy stimulation waveforms. The stimulation waveform of the present disclosure may be dynamically shaped as a function of an individual patient's response. Such stimulation waveforms facilitate achieving lower capture thresholds which reduces the device's supply consumption thereby increasing longevity of the device and facilitate a reduction of tissue damage.
