Endoprosthesis delivery system
First Claim
Patent Images
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.

19. 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. - View Dependent Claims (22)

20. 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 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; 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 (23)
