Patent ID: 8560087

Claim:
A medical electrical lead comprising: an insulative lead body including a proximal portion and a distal portion; a proximal connector connected to the proximal portion of the insulative lead body, the proximal connector including a connector pin having a first electrical contact and a connector body having a second electrical contact, wherein the proximal connector has a rotatable portion that includes the connector pin and a portion of the connector body that has the second electrical contact, wherein the rotatable portion is rotatable with respect to the insulative lead body; first and second electrodes; a composite conductor comprising a first conductor electrically coupled to the first electrical contact of the connector pin and the first electrode to form a first electrical pathway and comprising a second conductor electrically coupled to the second electrical contact on the connector body and the second electrode to form a second electrical pathway, wherein the first and second conductors are co-radial and at least one of the first and second conductors comprises a coating of insulative material that insulates the first conductor from the second conductor; and an actuation member coupled between the first and second electrodes and the composite conductor such that rotating the rotatable portion of the proximal connector transmits torque through each of the first and second conductors of the composite conductor to the actuation member and results in both rotational and linear motion of the first and second electrodes.
