  • Coating compositions for bioactive agents
    Patent number: 7544673
    Abstract: A coating composition and related method for use in applying a bioactive agent to a surface in a manner that will permit the bioactive agent to be released from the coating in vivo. The composition is particularly well suited for coating the surface of implantable medical device, such as a stent or catheter, in order to permit the device to release bioactive agent to the surrounding tissue over time. The composition includes a plurality of compatible polymers having different properties that can permit them to be combined together to provide an optimal combination of such properties as durability, biocompatibility, and release kinetics.

  • METHOD AND APPARATUS FOR COMPOSITE DRUG DELIVERY MEDICAL DEVICES
    Publication number: 20090041824
    Abstract: A medical device and method for drug delivery employing a 3-dimensional pattern of a polymer support material (e.g., that is degradable after implant in a body), a drug associated with the polymer support material, and an adhesive that adheres the polymer support material and associated drug to body tissue. The adhesive may persist to maintain the device in a suitable position for a suitable time (e.g., until after the polymer support material begins to degrade to release the drug), and the drug may be arranged in discrete areas of the 3-dimensional pattern that are separated from each other. The pattern may be produced in whole or in part before deployment at a body site, or may be produced in whole or in part directly at a tissue surface.
