摘要:
A stent attachment and deployment mechanism is utilized to prevent the distal end of an endoprosthesis comprising fixation barbs or other fixation mechanism from deploying prior to the remaining sections of the fixation device. With this stent attachment and deployment mechanism accurate deployment may be achieved.A stent attachment and deployment system comprises: 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 comprises a first collar mounted on the inner member at a first side of the distal end of the endoprosthesis, a second collar mounted on the inner member at a second side of the distal end of the endoprosthesis, and at least one hold down wire releasably interconnected between the first and second collars and to the distal end of the prosthesis for securing the distal end of the prosthesis in an unexpanded state.
