1. A device for interfacing with a syringe body and syringe plunger for delivering a wire into a tissue workspace, the device comprising:
a needle configured for coupling with the syringe body and having at least one bore for guiding a proximal end of the wire into the workspace;
a housing configured for coupling with the syringe body and including at least one portion for engagement by a user;
a slide configured for coupling with the syringe plunger for moving together and in a same direction with the syringe plunger between a forward position and a retracted position, the slide including at least one portion for engagement by the user;
the slide including a wire holding structure for releasably holding a distal end of the wire for moving the distal end and advancing the proximal end of the wire forwardly in the needle when the slide moves together with the syringe plunger from the forward position to the retracted position;
a wire advancing mechanism configured for translating the movement of the wire distal end by the wire holding structure for advancing the proximal end of the wire forwardly in the needle when the wire holding structure and the syringe plunger move together from the forward position to the retracted position.
