  • Patent number: 9457129
    Abstract: The present invention relates to medical prostheses and methods of manufacturing those devices. In particular, the prostheses are temporarily stiffened meshes with particular coatings to provide initial stiffness and thereby permit easier surgical handling for treatment or reconstruction of soft tissue defects. Preferred embodiments include surgical meshes coated with one or more biodegradable polymers that can act as a stiffening agent by coating the filaments or fibers of the mesh to temporarily immobilize the contact points of those filaments or fibers and/or by increasing the stiffness of the mesh by at least 1.1 times its original stiffness. The devices of the invention can also provide relief from various post-operative complications associated with their implantation, insertion or surgical use.

  • Patent number: 9447523
    Abstract: A melt blowing process comprising: (a) providing a thermoplastic polymer material that includes at least one or a plurality of polyester polymers and at least one or a combination of different meltable metal phosphinates; and (b) melt blowing the thermoplastic polymer material into at least one fiber or a plurality of fibers, with each fiber having a diameter or thickness that is less than about 10 microns. The metal phosphinate is in an amount that (a) reduces the viscosity of the polyester polymer and (b) functions as a crystallizing agent, which at least promotes crystallization of the polyester polymer, when the thermoplastic polymer material is melt blown into the at least one fiber. Non-woven and woven fibrous structures can be made using fibers made from this process.

  • Patent number: 9428848
    Abstract: A method for melt spinning, stretching, and winding a multifilament thread to form an FDY-yarn as well as a device for performing the method are presented. Hereby, a plurality of filaments are first extruded from thermoplastic melt, cooled to a temperature below the glass transition temperature of the thermoplastic material, and gathered to form a filament bundle without adding a preparation fluid. The filament bundle is then drawn-off at a speed above 1,500 m/min., heated to have a temperature above the glass transition temperature of the thermoplastic material, and stretched at a drawing speed above 4,000 m/min. Preparation of the filament bundle with a preparation fluid and winding the thread to form a spool is then performed. The device has the preparation device arranged in a zone of the thread course between the drawing device and the winding device, in which the thread has a thread-running speed above 4,000 m/min.

    Abstract: A method of forming a reinforced tubular medical device in a continuous operation, and a medical device formed by the continuous method. An elongated core capable of movement about a line is provided. An elongated tubular member is formed around a moving length of the core by extruding a coating of a functionalized polymer around the moving core length, applying a reinforcing member to an outer surface of the functionalized polymer coating along the moving length, and extruding a polymeric outer jacket over the functionalized polymer and reinforcing member along the moving length, such that a bond is formed between the functionalized polymer and the polymeric outer jacket. The elongated tubular member is cut to desired length to form the tubular medical device, and the core is removed from the device.
