Assignee: BOSTON SCIENTIFIC NEUROMODULATION CORPORATION
Field: Medical technology (Instruments)
Classification: CPC H  A | IPC A  H

Claim 19:
20. A method for operating a pulse generator having a plurality of electrode nodes, each electrode node configured to be coupled to an electrode configured to contact a patient's tissue, the method comprising:
receiving at the pulse generator digital data specifying a magnitude of a total anodic current amplitude to be produced at the electrode nodes;
producing a first current with a magnitude indicative of the total anodic current amplitude;
producing a plurality of different second currents from the first current, wherein each of the second currents is independently calibrated;
receiving the independently-calibrated second currents at a plurality of second DACs, wherein each of the second DACs is associated with one of the electrode nodes; and
selecting at least one second DAC to amplify its received second current to produce an anodic stimulation current at its associated electrode node.
