    摘要： The drug eluting folded stent and a stent delivery system, which includes a stent having a plurality of struts interconnected to form a tubular body. At least one of the struts includes a U-shaped strut having in cross-section a first leg, a second leg, and a closed end connecting the first leg and the second leg, wherein the first leg, the second leg, and the closed end define a recess having a drug release opening opposite the closed end; and a drug coating disposed on the first leg, the second leg, and the closed end within the recess. The drug release opening is sized to release a drug from the drug coating at a predetermined drug elution rate.

    摘要： Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.

    摘要： Disclosed are medical devices having textured surfaces and biocompatible coatings disposed thereon. The textured surfaces allow for durable coatings to be applied to the medical device without a previous pre-coating having been applied. The biocompatible coating can further comprise a bioactive agent.
