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; and
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;
wherein the adjustable stop comprises;
a shaft coupled to the inner member, the shaft having an outer surface, anda member that is moveable along the outer surface of the shaft in the proximal direction,wherein the member includes an orifice configured to receive a fastening 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.

7. 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 an outer surface; and a member that is moveable along the outer surface of the shaft in the proximal direction, the member including an orifice; and a set screw in the orifice of the member, the set screw having a first position in which, as the member moves in the proximal direction along the outer surface of the shaft, the wire moves in the proximal direction, and a second position in which, as the member moves in the proximal direction along the outer surface of the shaft, the wire does not move in the proximal direction.

8. A stent delivery system, comprising:
-
an inner member having a distal portion; a stent disposed about the distal portion of the inner member; an outer member disposed about the stent; a pull wire attached to the outer member and extending proximally therefrom to a handle; wherein the handle includes a member having a groove formed therein; wherein the pull wire is disposed in a groove; wherein the member has an orifice formed therein; and a fastening device that is configured to be disposed in the orifice.
-
- 10. The stent delivery system of claim 10, wherein the orifice is threaded.
- 13. The stent delivery system of claim 13, wherein when the set screw is not disposed in the orifice, the pull wire is not secured to the member.
