Endoprosthesis delivery system
First Claim
1. 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.

Abstract
Endoprothesis delivery systems and methods for making an using the same. An example medical endoprosthesis delivery system may include an inner member. An outer member may at least partially surround the inner member. The inner member and the outer member may be configured so that an implantable medical endoprosthesis can be disposed therebetween. A coupling device may be 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 may be 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.

11. 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 wire coupled to a portion of the outer member so that, when there is substantially no slack in the wire, as the wire moves in a proximal direction the portion of the outer member moves in the proximal direction; and an adjustable stop coupled to the wire so that, when there is slack in the wire, as the adjustable stop is moved in the proximal direction, the amount of slack in the wire can be reduced, the adjustable stop comprising; a shaft coupled to the inner member, the shaft having a threaded outer surface; a nut 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 nut moves in the proximal direction, the nut engages the second member, wherein; when the nut is engaged with the second member, as the nut moves in the proximal direction, the second member moves in the proximal direction; when the nut is not engaged with the second member, the nut can move independently of the wire; and the second member is coupled to the wire so that, as the second member moves in the proximal direction, the wire moves in the proximal direction. - View Dependent Claims (12)
