Abstract
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.
