Abstract
A device for driving a flexible wire having a helical coil therearound along its length comprises a hollow shaft adapted to receive the wire and a motor for rotating the hollow shaft in either direction about its longitudinal axis. The shaft has a projection extending into the interior of the hollow shaft and adapted to engage the wire in the gap between adjacent turns of the helical coil. Upon rotation of the shaft and thereby the projection, the wire is driven longitudinally through the hollow shaft.
