1. An intraluminal medical device delivery system, comprising:
- an elongate tubular member having a distal end adapted for insertion into a body vessel;
a dilator having a distal end adapted for insertion into the body vessel, the dilator disposed in the tubular member and extending substantially coaxially with the tubular member, the distal end of the dilator having a device chamber formed therein defined by an exterior surface of the dilator;
an intraluminal medical device disposed radially between the tubular member and the dilator in the device chamber; and
a means for resisting relative movement between the intraluminal medical device and the dilator during relative movement between the dilator and the tubular member.

Abstract
Delivery systems and methods of making delivery systems are provided. A delivery system according to the invention facilitates delivery of an intraluminal medical device to a point of treatment in a body vessel. A dilator includes a means for resisting relative movement between an associated intraluminal medical device and the dilator during relative movement between the dilator and an associated tubular member disposed about the dilator.

20. An intraluminal medical device delivery system, comprising:
-
a dilator defining a device chamber;
a first coating disposed in the device chamber;
an intraluminal medical device disposed in the device chamber adjacent the first coating;
an elongate tubular member disposed about the dilator and adjacent the intraluminal medical device;
a second coating disposed on the tubular member and adjacent the intraluminal medical device;
wherein the first coating resists relative movement between the dilator and the intraluminal medical device during relative movement between the dilator and the tubular member.
