A method of securely mounting a stent on a balloon of a catheter. The method generally includes crimping a stent on a balloon of a catheter at least one time, and positioning the balloon with the stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold, or within a sheath, in two stages as the stent is restrained from radially expanding. The method may include crimping the stent onto the balloon one or two times during processing. The method increases retention of the stent on the balloon catheter following sterilization.

Method for retaining a vascular stent on a catheter

A stent retention mold includes two half-molds, each half-mold including a stent supporting surface, and a plurality of protrusions disposed on at least one of the stent supporting surfaces. A stent retention method includes retaining a stent to a balloon using a split mold that includes a stent supporting surface having a plurality of protrusions, so that a portion of the balloon extends through a gap of the stent into a space between two protrusions.

Stent retention mold and method

A method of securely mounting a stent on a balloon of a balloon catheter. The method generally includes crimping a stent on a balloon of a balloon catheter, and positioning the balloon with the drug delivery stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold as the mold radially restrains the stent from expanding. The stent is re-crimped on the balloon after removal from the mold to increase retention of the stent on the balloon.

A method of mounting a drug delivery stent on a balloon of a balloon catheter. The method securely mounts the drug delivery stent on the balloon without damaging the drug delivery layer of the stent. In one embodiment, the method generally comprises positioning a drug delivery stent on a balloon of a balloon catheter, and positioning the balloon with the drug delivery stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold as the mold radially restrains the stent from expanding, to mount the stent on the balloon without damaging the drug delivery layer of the stent.
