Abstract:
1. An implantable medical system having electronic circuitry and an electrode coupled to the electronic circuitry, the electronic circuitry comprising: a microprocessor programmed to detect a predetermined event in response to signals received from the electrode; a controller coupled to the microprocessor, wherein the controller is programmed to generate a control signal in response to detection of the predetermined event; and a delivery circuit coupled between the controller and the electrode, the delivery circuit including: wherein the coupling circuit configures a second of the plurality of capacitors to be serially stacked onto the first capacitor for discharge of energy during a second of the intervals, and wherein the coupling circuit controls a timing of the stacking of the second capacitor for discharge of energy from the first and second capacitor to generate a stimulation waveform having a stepped leading-edge.
