A delivery apparatus for a stimulating catheter has a conductive wire wound within a reel dispenser. The reel dispenser has a base portion and a rotating portion that are coupled at the axle with the rotating portion rotatable relative to the base portion. The proximal region of the conductive wire is in electrical connection with the axle of the dispenser. A method for delivering a stimulating catheter includes introducing the distal regions of the conductive wire and catheter into a subject, rotating the rotating portion of the reel dispenser relative to the base portion whereby the catheter and conductive wire are advanced into the subject, providing an electrical current to the conductive wire through the axle, and rewinding the rotating portion of the reel dispenser relative to the base portion whereby the conductive wire is retracted in a proximal direction through the catheter.
