  • Energetically-controlled delivery of biologically active material from an implanted medical device
    Patent number: 7585320
    Abstract: A medical device and system capable of providing on-demand delivery of biologically active material to a body lumen patient, and a method of making such medical device. A first coating layer comprising a biologically active material and optionally a polymeric material is disposed on the surface of the medical device. A second coating layer comprising magnetic particles and a polymeric material is disposed on the first coating layer. The second coating layer, which is substantially free of a biologically active material, protects the biologically active material prior to delivery. The system includes the medical device and a source of energy, such as an electromagnetic or mechanical vibrational energy. When the patient is exposed to the energy source, the magnetic particles move out of the second coating layer and create channels therein through which the biologically active material can be released.

  • Coating comprising an adhesive polymeric material for a medical device and method of preparing the same
    Publication number: 20070190104
    Abstract: This invention is directed to a coating for a medical device in which the coating comprises an adhesive polymeric material, having a certain degree of surface tack, disposed on at least a portion of the medical device surface. The coating also comprises an outermost coating layer comprising a biologically active material in particulate form disposed on and adhering to at least a portion of the first coating layer. The coating is capable of delivering a biologically active material to a patient. The invention is also directed to a method for manufacturing such a coated medical device.
