A stent attachment and deployment system comprising:
an inner member having a proximal end and a distal end;
an endoprosthesis having a proximal end and a distal end mounted coaxially about the inner member; and
a restraining mechanism mounted at least partially coaxially about the inner member, the restraining mechanism comprising a collar configured for engaging the distal end of the endoprosthesis, a hold down wire for securing the distal end of the endoprosthesis to the collar and an activation wire releasably connected to the hold down wire, the activation wire being configured to position the hold down wire such that the hold down wire secures the distal end of the endoprosthesis to the collar as long as the activation wire remains secured to the hold down wire and wherein when the activation wire is moved in the proximal direction it releases the hold down wire. |
