Abstract: An implantable control module for an electrical stimulation system includes a housing and a connector shell extending into the housing. The housing and the connector shell collectively form a sealed cavity. The connector shell has a longitudinal length, a sidewall with a cavity-facing surface, a first end open to an environment external to the housing, and an opposing closed second end. The connector shell defines a connector lumen extending within the connector shell and open at the first end to receive a portion of a lead or lead extension. Connector contacts are arranged along the connector lumen within the connector shell. An electronic subassembly is disposed in the sealed cavity. Interconnect conductors electrically couple the electronic subassembly to the connector contacts and extend from the connector shell within the sealed cavity.

Abstract: An implantable pulse generator (IPG) is disclosed having an improved ability to steer anodic and cathodic currents between the IPG's electrodes. Each electrode node has at least one PDAC/NDAC pair to source/sink or sink/source a stimulation current to an associated electrode node. Each PDAC and NDAC receives a current with a magnitude indicative of a total anodic and cathodic current, and data indicative of a percentage of that total that each PDAC and NDAC will produce in the patient's tissue at any given time, which activates a number of branches in each PDAC or NDAC. Each PDAC and NDAC may also receive one or more resolution control signals specifying an increment by which the stimulation current may be adjusted at each electrode. The current received by each PDAC and NDAC is generated by a master DAC, and is preferably distributed to the PDACs and NDACs by distribution circuitry.
