An implant release mechanism for releasing, for example, a stent (60) is provided with three restraining wires (62) which pass in the space between a wire guide catheter (24) and a pusher sheath or dilator (30) and are arranged substantially equi-angularly threrearound. Each restraining wire (62) holds both the proximal and distal ends of the stent (60), in this case each holding a proportion of the ends of the stent (60). When the restraining wires (62) are pulled they will first unwrap from the proximal end of the stent (60) and will then release the distal end of the stent (60) so as to allow the stent to become fully deployed within the lumen of the patient. The use of common release wires improves deployment of implants and reduces the number and volume of components in the device, thereby allowing it to occupy a smaller volume.
