1. A system, comprising:
- an inner member;
an outer member disposed about the inner member so that an implantable endoprosthesis can be disposed between the inner and outer members; and
a friction-enhancing device configured to reduce distal movement of the inner member when the outer member is moved proximally.

5. A system, comprising:
-
an inner member having a distal region; and
an outer member having a distal region that surrounds the distal region of the inner member so that an implantable endoprosthesis can be disposed between the distal region of the inner member and the distal region of the outer member;
wherein the distal region of the outer member has inner surface with an etched region. - View Dependent Claims (6, 7)

8. A system, comprising:
-
an inner member having a distal region; and
an outer member having a proximal region and a distal region, the distal region surrounding the distal region of the inner member so that an implantable endoprosthesis can be disposed between the distal region of the inner member and the distal region of the outer member;
wherein the proximal and distal regions of the outer member each have an inner surface having a coefficient of friction, the coefficient of friction of the inner surface of the proximal region of the outer member being different than the coefficient of friction of the inner surface of the distal region of the outer member. - View Dependent Claims (9, 10)

11. A self-expanding implantable endoprosthesis having an etched outer surface.
-
12. A self-expanding implantable endoprosthesis having an endoprosthesis body with an outer surface and having a coating on the outer surface of the endoprosthesis body, wherein the coating comprises a material having a coefficient of friction higher than the coefficient of friction of the outer surface of the endoprosthesis body.

13. A system comprising:
-
an inner member;
an outer member; and
a self-expanding implantable endoprosthesis disposed between the inner and outer members;
wherein the endoprosthesis has an etched outer surface.

14. A system comprising:
-
an inner member having a distal region; and
an outer member having a distal region that surrounds the distal region of the inner member;
an implantable endoprosthesis disposed between the distal region of the inner member and the distal region of the outer member, the implantable endoprosthesis having an outer surface having a coefficient of friction;
a wedge attached to the inner member, the wedge having an outer surface in contact with an inner surface of the outer member, the outer surface of the wedge having a coefficient of friction higher than the coefficient of friction of the outer surface of the endoprosthesis. - View Dependent Claims (15, 16, 17, 18, 19, 20)

an inner member having a distal region;
an outer member having a distal region that surrounds the distal region of the inner member;
an implantable endoprosthesis disposed between the distal region of the inner member and the distal region of the outer member, the implantable endoprosthesis having an outer surface having a coefficient of friction; and
a wedge attached to the outer member, the wedge having an inner surface in contact with an outer surface of the inner member, the inner surface of the wedge having a coefficient of friction higher than the coefficient of friction of the outer surface of the endoprosthesis. - View Dependent Claims (22, 23, 24, 25)

an inner member having a distal region;
an outer member having a distal region that surrounds the distal region of the inner member so that an implantable endoprosthesis can be disposed between the distal region of the inner member and the distal region of the outer member; and
means for reducing distal movement of the implantable endoprosthesis when the outer member is retracted. - View Dependent Claims (27, 28, 29)
