1. An implantable medical device, comprising:

  • an elongated body extending from a proximal end to a distal end adapted to be engaged along a target site;

    a delivery member extending through the elongated body and adapted to deliver a voltage sensitive dye outward from the distal end of the elongated body to the target site via the delivery member;

    an optical transmission member, extending through the elongated body, adapted to transmit a signal associated with an action potential corresponding to the target site, andcontrol circuitry coupled to the transmission member for determining whether the action potential is detected from the signal transmitted by the transmission member;

    wherein the transmission member is formed as a helical coil positioned about the delivery member.
