Support device for a stent and a method of using the same to coat a stent

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.

A stent crimping tool for firmly and uniformly crimping a stent onto a balloon catheter is constructed from a stationary plate and a sliding platform connected to the stationary plate and slidable linearly relative thereto. A closing plate is hinged to the sliding platform so that it at least partially overlies the stationary plate in a down position, and swings away from the stationary plate to an up position, whereby the stent already having been hand crimped onto the balloon catheter is placed on the stationary plate from a lateral position, and the closing plate is moved to the down position to hold the stent between the closing plate and the stationary plate so that an external force on the closing plate as well as translational motion of the closing plate together crimp the stent onto the balloon catheter. The surfaces engaging the stent may be covered by elastomeric pads having ridges corresponding in location to respective rings or cylindrical elements of the stent.

Method and apparatus for a stent crimping device

The drug loaded polymeric material containing a therapeutic drug can be applied to a structure of an intravascular stent. A therapeutically effective amount of a therapeutic drug is incorporated into such a layer of polymeric material, without significantly increasing the thickness of the stent, to avoid interfering with the function of the stent. The drug loaded polymer coating of the stent can formed to include pores, can be multi-layered to permit the combination of a plurality of different drug containing materials in a single stent, and can include a rate controlling membrane to allow for controlled retention and delivery of selected drugs within the affected blood vessel upon implantation. The layer of polymeric material is manufactured by combining the selected polymeric material with a relatively high loading of the therapeutic drug in a thermal process, such as coextrusion of the therapeutic drug with the polymeric material. The therapeutic drug is dispersed and incorporated into the polymer as small particles, preferably having a maximum cross-sectional dimension of 10 microns.
