A medical implant deployment system for placing an implant at a preselected site within a vessel, duct or body lumen of a mammal. The reusable deployment system includes a mechanical coupling assembly at the distal end of a positioning member, having a first configuration in which the coupling assembly distal end is insertable or removable from the implant proximal end and a second configuration where the coupling assembly distal end is interlockingly engaged with the implant proximal end. Once the implant is properly positioned the coupling assembly is actuated, thereby releasing the implant at a desired position within the body.
