  • Patent number: 9056152
    Abstract: A medical device having a polymer-free outer surface layer comprising a crystalline drug selected from the group consisting of everolimus, tacrolimus, sirolimus, zotarolimus, biolimus, and rapamycin. The device may be produced by a method comprising the steps of providing a medical device; applying a solution of the drug to said portion of the outer surface to form a coating of amorphous drug; and vapor annealing the drug with a solvent vapor to form crystalline drug; wherein a seed layer of a crystalline form of said drug having a maximum particle size of about 10 ?m or less is applied to at least said portion of the outer surface of the device before or after applying the drug solution, but before vapor annealing the amorphous coating.

  • Publication number: 20120078227
    Abstract: Drug delivery balloons are configured with a carrier film of biodegradable polymer. The carrier film includes a drug or has a drug carried thereon. The balloons utilize a film layering system that is designed to separate the carrier film substantially intact from the balloon when expanded, so that the carrier film and the drug are left in place at the tissue site.

  • Publication number: 20120053678
    Abstract: An implantable metallic medical device having a dual-layered coating with a primer layer having functional groups capable of forming an organo-metallic complex with iron species and a second biocompatible polymer layer. The primer layer is baked onto the metallic medical device functioning as a tie layer between the surface of the medical device and a second biocompatible polymer layer disposed on the primer layer. Baking improves tie layer adhesion and in some cases provides an organo-metallic complex with the metal substrate. The second biocompatible polymer may can a therapeutic agent.

  • Publication number: 20110263921
    Abstract: A renal denervation apparatus includes a treatment element dimensioned for deployment on or within a renal artery of a patient. The treatment element comprises a predefined pattern arranged to complete at least one revolution of the treatment element. The apparatus includes a treatment source. The treatment source and treatment element are configured to cooperatively facilitate communication of an agent from the treatment source to the pattern arrangement of the treatment element. The treatment element is configured to deliver denervation therapy using the agent via the pattern arrangement to one or more regions of the renal artery adjacent the pattern arrangement, such that at least one complete revolution of the renal artery is subjected to the denervation therapy.
