Patent ID: 8412347

Claim:
A lead for use with an implantable device, the lead having at least two satellites formed along with its length, the lead having at least one conductor extending along at least part of its length, the at least one conductor extending to and electrically connected to each of the at least two satellites and further extending to an end of the lead for electrical connection to the implantable device, with each satellite comprising: at least one electrode positioned for contact external to the lead; and an integrated circuit electrically connected with the at least one conductor and electrically connected with the at least one electrode, the integrated circuit comprising: a first timing circuitry coupled with the at least one conductor and powered from the at least one conductor; a first charge pump coupled with the at least one conductor and the first timing circuitry and powered from the at least one conductor and switched by the first timing circuitry; a second timing circuitry coupled with the first charge pump and powered from the first charge pump; a second charge pump coupled with the at least one conductor and the second timing circuitry, the second charge pump powered from the at least one conductor and switched by the second timing circuitry; a third charge pump coupled with the at least one conductor and the second timing circuitry, the third charge pump powered from the at least one conductor and switched by the second timing circuitry out of phase with respect to switching of the second charge pump; and a control means controlling connections between the at least one electrode and the at least one conductor, the control means coupled with the second charge pump and the third charge pump and powered from the second charge pump and the third charge pump.
