Abstract
A stent cover for enclosing a compressible stent during a stent crimping process, the stent cover having an outer sheath with a proximal end, a distal end, an end portion at the distal end of the sheath having a first diameter, and a stent-retaining portion adjacent to the end portion and having an uncompressed diameter that is larger than the first diameter of the end portion for retaining a stent in its uncompressed condition.
Claims25
A stent cover for enclosing a compressible stent during a stent crimping process, the stent cover comprising an outer sheath having a single-piece construction and comprising:
- a proximal end;
- a closed distal end;
- a generally cylindrical end portion extending from the closed distal end of the sheath toward the proximal end and having an inner diameter for at least partially surrounding a tip of a catheter;
- 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
- a flange extending from a proximal end of the locating portion, wherein the flange extends beyond an outer diameter of the locating portion at the proximal end of the sheath.
