Patent ID: 11969600
Assignee: ADVANCED NEUROMODULATION SYSTEMS, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. An implantable medical device (IMD), comprising:
a power supply;
one or more processors;
communication circuitry operative to effectuate a machine-to-machine (M2M) communication link with an external device using a wireless communication protocol;
a voltage multiplier (VM) configured to generate an adjustable target voltage at a VM node based on a voltage supplied by the power supply;
at least one stimulation engine operative to energize at least a portion of a plurality of electrodes of a lead system when implanted proximate to a tissue of a patient; and
output switching circuitry operative to drive a plurality of output nodes, each output node connectable to a corresponding electrode of the plurality of electrodes when implanted, the output switching circuitry comprising, for each respective output node a switching portion including:
a dual mode (DM) switch for selectively coupling the respective output node to the VM node operative to power an anodic node of the at least one stimulation engine; and
one or more stimulation engine selection (SES) switches operative to be disposed in a series connection with the DM switch, wherein a select one of the one or more SES switches is configured for selectively coupling the respective output node to a cathodic node of the at least one stimulation engine, and wherein the DM switch and the select one of the one or more SES switches are activated to close so as to effectuate an internal circuit path in the output switching circuitry of the IMD in a self-test mode in response to one or more digital control signals generated under control of the one or more processors operating responsive to a mode selection control signal from the external device while the IMD is disposed in a sealed package condition.
