Patent ID: 7658757

Claim:
A medical endoprosthesis delivery system, comprising: an inner member; an outer member at least partially surrounding the inner member, the inner member and the outer member being configured so that an implantable medical endoprosthesis can be disposed therebetween; a coupling device coupled to a portion of the outer member so that, when there is substantially no slack in the coupling device, as the coupling device moves in a proximal direction the portion of the outer member moves in the proximal direction; an adjustable stop coupled to the coupling device so that, when there is slack in the coupling device, as the adjustable stop is moved in the proximal direction, the amount of slack in the coupling device can be reduced; and wherein the adjustable stop comprises: a shaft coupled to the inner member, the shaft having a threaded outer surface; a first member that is moveable in the proximal direction along the threads of the outer surface of the shaft; and a second member configured so that, as the first member moves in the proximal direction, the first member engages the second member, wherein when the first member is not engaged with the second member, the first member can move independently of the coupling device.
