Assignee: ADVANCED NEUROMODULATION SYSTEMS, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 12:
13. A stimulation therapy method using an external programmer device and an implantable medical device (IMD), the IMD including a battery and a lead system comprising one or more leads configured to be positioned proximate to a patient's tissue, wherein each lead includes a plurality of electrodes, the method comprising:
providing a first voltage multiplier configured to generate a range of target voltages at an output node based on a voltage supplied by the battery;
providing a plurality of stimulation engines (SE), each SE respectively including: a second voltage multiplier that is coupled to the output node of the first voltage multiplier and that is operative to drive an anodic node; and a current regulator that is powered by a floating power supply and that is coupled to a cathodic node; and
independently applying, via the external programmer device, multiple stimulation therapies in a concurrent manner to respective portions of the electrodes of the lead system by actuating a selector of the IMD according to respective stimulation sets, wherein the selector is configured to selectively couple the anodic node and the cathodic node of a respective SE to a select portion of the electrodes.
