Abstract: A stent graft adapted to telescopically receive a secondary stent graft characterized in that the stent graft comprises at least one socket communicating with at least one opening in the stent graft. The at least one socket comprises an elastic wall that forms a lumen with a stent at least partially encased within the wall. The socket can be adapted for use with stent grafts for implantantation in an aneurysm.

Abstract: A balloon expandable covered stent consists of a plurality of primary stent units, each having an undulating shape defined by a series of primary strut members converging to form peaks and valleys. The primary stent units are assembled into a single cylindrical structure of the stent by connecting corresponding peaks with secondary strut members. Generally, surfaces of the stent may then coated with a polymeric, hyper-elastic material, preferably Thoralon®, by pre-expanding the stent prior to coating.

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, where 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 may be posited over the bioactive material layer 18, where 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.

Abstract: Methods for coating medical devices for implantation within a body vessel are provided comprising providing a cylindrical container, placing a medical device inside the cylindrical container, and applying a polymer in liquid form inside the container.

Abstract: This invention is directed to graft materials for implanting, transplanting, replacing, or repairing a part of a patient and to methods of making the graft materials. The present invention is also directed to stent grafts and endoluminal prostheses formed of the graft materials. More specifically, the present invention is a graft material which includes porous polymeric sheet, extracellular matrix material (ECM) disposed on at least a portion of the porous polymeric sheet and at least one polymer layer disposed on at least a portion of the ECM. The ECM may be in a gel form. The polymeric sheet and the polymer layer may be made from foam material and may comprise a polyurethane urea and a surface modifying agent such as siloxane.

Abstract: A stent graft (10) has a tubular body of a biocompatible material and a side arm (20) fastened to the tubular body. A tubular extension piece (24) is sealingly joined to the end of the side arm and extends from it. It can be joined with adhesive or stitching. The extension piece can be formed from an elastomeric biocompatible material such as Thoralon™. The extension piece can have a resilient reinforcement 44 embedded into it and extending longitudinally. The extension piece is tucked back into the side arm during deployment of the stent graft into a body lumen.

Abstract: A variable curvature stent limb is disclosed herein. A stent derived from a plurality of these variable curvature stent limbs may be highly compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.

Abstract: An endoluminal device comprises a stent and a tubular graft supported by the stent. The graft has a proximal and a distal opening and comprises a synthetic material and a bioremodelable material. The bioremodelable material is disposed on an exterior surface in at least one band adjacent at least one of the proximal and distal openings.
