Abstract

A programmable output connector of an implantable cardioverter-defibrillator (ICD), or similar implantable medical device, allows each of a multiplicity of output terminals to be selectively connected to either a positive or a negative output bus of the ICD. The positive and negative output buses of the ICD, in turn, are switched to an output capacitor, or equivalent output circuit, of the ICD. An electrical charge stored on the output capacitor, or otherwise generated by the output circuit, is presented to the multiplicity of output terminals in accordance with a programmed polarity. The programmed polarity causes a selected one or group of the multiplicity of output terminals to be connected to the positive output bus, and a selected other or group of the multiplicity of output terminals to be connected to the negative output bus. Respective electrodes designed for contacting cardiac tissue may then be electrically connected to each one of the multiplicity of output terminals. An electrical charge available on the positive and negative output buses may then be transferred to the body tissue as an electrical shock or stimulus through the electrodes in accordance with the programmed polarity.
