Patent ID: 7805189

Claim:
An implantable medical device delivering a therapy, the therapy being dynamically variable among a plurality of discrete output voltages, comprising: a power source having an output; a first electrode and a second electrode; a therapy module, operatively coupled to the power source, the first electrode and the second electrode, comprising a dynamically configurable capacitor arrangement providing a plurality of lines, each of the plurality of lines having one of the plurality of discrete output voltages; wherein the dynamically configurable capacitor arrangement comprises a plurality of capacitors configured with: a first one of the plurality of capacitors providing, at least in part, a first one of the plurality of discrete output voltages on a first one of the plurality of lines and; a combination of the first one of the plurality of capacitors and a second one of the plurality of capacitors providing, at least in part, a second one of the plurality of discrete output voltages on a second one of the plurality of lines; and a controller, operatively coupled to the therapy module, selectively coupling at least one of the plurality of lines to at least one of the first electrode and the second electrode to dynamically provide an individual one of the plurality of discrete output voltages across the first electrode and the second electrode.
