  • Publication number: 20150196692
    Abstract: System for treating vascular disease comprising a balloon having an outer surface for temporary contact with a vessel wall when in an expanded state, a coating disposed on at least a portion of the outer surface, the coating including an initial amount of a cytostatic agent selected from the group consisting of Zotarolimus (ABT578), everolimus, pimecrolimus, and a combination thereof, the coating being capable of maintaining a therapeutically effective amount of the cytostatic agent on the outer surface for delivery to a vessel wall, and further wherein between about 4.9% to about 23% of the initial amount of the cytostatic agent on the outer surface remains disposed on the outer surface after delivery of the therapeutically effective amount of the cytostatic agent to the vessel wall, and optionally, a stent disposed on the balloon.

  • Patent number: 9039748
    Abstract: A method for securing an implantable medical device onto a balloon which includes applying a coating, which includes a film-forming polymer and at least one solvent, to the outer surface of the balloon. The solvents can include alcohol, water, ether and combinations thereof. The film-forming polymer can include a zwitterionic polymer, such as, for example a phosphorylcholine polymer. The coating can be applied to the entire balloon surface or a portion of the surface. The implantable medical device is then positioned on the outer surface of the balloon and secured. The film-forming polymer is then allowed to cure in order to define an adhesive layer between an inner surface of the implantable medical device and the outer surface of the balloon. This method prevents or reduces the leaching or redistribution of any therapeutic agents dispersed within or on the surface of the implantable medical device.
