Patent ID: 8874233

Claim:
A system for modulating a physiological process, comprising: an implantable device comprising an energy source, the implantable device constructed and arranged to provide a signal; and an electrical lead body connected to the implantable device and comprising: a plurality of transducer contacts in close proximity to an end of the electrical lead body; a control unit positioned within the lead body in close proximity to the plurality of transducer contacts and constructed and arranged to enable precise delivery of signals to a predetermined treatment site, the control unit configured to receive at least one first input signal from the implantable device and to transmit a plurality of output signals to the plurality of transducer contacts, and further configured to receive at least one second input signal from the plurality of transducer contacts, the control unit comprising: at least one electrical input contact; and a plurality of electrical output contacts, wherein a quantity of the electrical output contacts is greater than a quantity of the electrical input contacts, wherein the plurality of output signals is modulated in response to the at least one second input signal from the plurality of transducer contacts, and the plurality of output signals is based at least in part on the at least one first input signal from the implantable device and on a control function of the control unit.
