a generally cylindrical stent-retaining portion adjacent to the end portion and having an uncompressed inner diameter that is larger than the inner diameter of the end portion for retaining a stent in an uncompressed condition;
a locating portion adjacent to the stent-retaining portion and having a larger inner diameter than the uncompressed inner diameter of the stent-retaining portion; and
