Medical device lead including a rotatable composite conductor

摘要

A medical electrical lead includes a proximal connector including a rotatable portion and first and second co-radial conductors coupled to the rotatable portion and extending distally from the rotatable portion. An actuation member is coupled between an electrode and the first and second conductors such that rotating the rotatable portion of the proximal connector transmits torque through the co-radial first and second conductors to the actuation member and results in both rotational and linear motion of the electrode.
