  • Publication number: 20100106256
    Abstract: A graft prostheses (11), materials and method for implanting, transplanting, replacing, or repairing a part of a patient. The graft prosthesis includes a purified, collagen-based matrix structure removed from a submucosa tissue source. The submucosa tissue source is purified by disinfection and removal steps to deactivate and remove contaminants, thereby making the purified structure biocompatible and suitable for grafting on and/or in a patient.

  • Publication number: 20070203520
    Abstract: Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.

  • Publication number: 20070168012
    Abstract: Methods of making coated implantable medical devices are provided. The methods include positioning a first layer comprising a bioactive on at least a portion of a structure, and positioning at least one porous layer over the first layer. The at least one porous layer has a thickness adequate to provide a controlled release of the bioactive.

  • Publication number: 20070050010
    Abstract: A coated implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer 16 posited on one surface of the structure; and at least one layer 18 of a bioactive material posited on at least a portion of the coating layer 16, wherein the coating layer 16 provides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layer 20 can be posited over the bioactive material layer 18, wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structure 12 is a coronary stent. The porous layer 20 includes a polymer applied preferably by vapor or plasma deposition and provides for a controlled release of the bioactive material.

  • Publication number: 20060195176
    Abstract: Bioactive-coated medical devices are provided, including coated vascular stents. The medical device coating can include a coating layer posited over at least a portion of the medical device surface, and can include a butyl methacrylate polymer or an ethylene-vinyl acetate copolymer in combination with a bioactive material that can function as both an immunosuppressive agent and an antiproliferative agent. Optionally, multilayer coatings can further include an adhesion promoting layer comprising parylene positioned between the coating layer and the medical device surface, a porous layer comprising butyl methacrylate positioned over at least a portion of the coating layer, or both. The coating layer preferably comprises between about 0.5 and 2.0 ?g/mm2 of the bioactive material on the outer surface of the medical device. The bioactive material can be absorbed into the coating layer, which can have a thickness of between about 0.5 ?m to about 5 ?m.
