    摘要: This disclosure relates to endolumenal medical devices coated with a taxane therapeutic agent in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous paclitaxel, dihydrate paclitaxel, or combinations thereof that provide durable coatings that release paclitaxel over a desired period of time, which can be on the order of hours, days or weeks. Preferred embodiments relate to medical device coatings of paclitaxel, or paclitaxel analogs or derivatives, having one or more polymorph solid forms that provide a prolonged release of paclitaxel within a body vessel without requiring a polymer carrier or barrier layer to achieve the desired rate of paclitaxel elution.

    摘要: A process for electrostatically coating a stent on a catheter. A conductor which is permanently affixed to the catheter contacts a stent mounted on the catheter. Conductive ink applied to the catheter may be used as the conductor. An electrical charge is applied to the conductor. The stent is then coated using an electrostatic coating process.

    摘要: An electropolishing apparatus and method are provided for polishing stents and other medical implants. The apparatus includes a motor that rotates a roller. The roller continuously rotates the medical implant to be electropolished. One of the advantages of the apparatus and method is that marks generated around the electrical contact between the anode and the medical implant are minimized. In addition, the medical implant is polished more evenly than conventional electropolishing systems.
