Patent ID: 8406898

Claim:
An apparatus comprising: an implantable lead, comprising an elongate lead body comprising a proximal portion and a distal portion, the lead comprising: a coupler, located at the proximal portion of the lead body, the coupler configured to be coupled to an implantable medical device; a conductor, extending from the coupler at the proximal portion of the lead body to a distal portion of the lead body; a first electrode located at the distal portion of the lead body; a first electrostimulation capacitor located at the distal portion of the lead body, the first electrostimulation capacitor of a capacitance value that is large enough to store an electrostimulation charge of an electrostimulation energy, wherein the electrostimulation energy is large enough to perform electrostimulation of tissue, the first electrostimulation capacitor configured to deliver the electrostimulation charge to electrostimulate the tissue; at least one first switch, located at the distal portion of the lead body and coupled to the conductor, the at least one first switch configured to selectively couple a first side of the first electrostimulation capacitor to the first electrode during a stimulating state, the at least one first switch configured to selectively couple the first side of the first electrostimulation capacitor to the conductor during a charging state; a controller circuit, located at the distal portion of the lead body, the controller circuit coupled to the conductor and configured to control charging of the electrostimulation capacitor from the implantable medical device via the conductor; a powering capacitor, located at the distal portion of the lead body, the powering capacitor coupled to the controller circuit; and at least one second switch located at the distal portion of the lead body and coupled to the conductor, the at least one second switch configured to selectively couple a first side of the powering capacitor to the conductor in a charging state and to selectively couple the first side of the powering capacitor to the controller circuit during a controller powering state to power the controller circuit.
