  • Patent number: 9592362
    Abstract: A method for making an absorbable microtube comprising the steps of a) extruding an absorbable polymer melt through a die to produce a molten extrudate; b) passing the molten extrudate vertically through an air gap ranging from about 0.1 to 0.5 inch as measured-from-the tip of the die to the surface of a liquid quenching medium to produce a quenched extrudate; and c) drawing the quenched extrudate to produce a drawn tube having an outer diameter of about 4 to about 12 mil; and an absorbable microtube that is made according to this method.

  • Patent number: 7875074
    Abstract: A preformed, seamless, three-dimensional, anatomically contoured prosthetic device for reinforcing breast tissue and supporting a breast implant includes a flat back wall, a concave front wall and a curved transitional region between the flat back wall and the front wall defining a smoothly curved bottom periphery. A concave receiving space is defined by the back wall and the front wall for at least partially receiving and supporting the breast implant therein. The three-dimensional prosthetic device is free of wrinkles, creases, folds or seams, which may have otherwise caused potential tissue irritation, bacteria hosting, infection and palpability problems.

  • Publication number: 20080221618
    Abstract: A co-extruded tissue grasping monofilament and a method for making the same. The monofilament includes a core made of a first material and extending along a length of said monofilament, and a plurality of tissue grasping elements extending outwardly from the core at least along a predetermined portion of the length of the monofilament. The plurality of tissue grasping elements are made of a second, different material having a greater stiffness than the first material. The method for making the monofilament is by co-extrusion.

  • Publication number: 20050074569
    Abstract: Fiber spinning of two polymer compositions wherein one of the compositions contains carbon nanotubes produces structures such as fibers, ribbons, yarns and films of carbon nanotubes. The polymers are removed and stabilization of the carbon nanotube material is achieved by post-spinning processes. The advances disclosed herein enable the carbon nanotube composites to be used in actuators, supercapacitors, friction materials and in devices for electrical energy harvesting.

  • Publication number: 20040110001
    Abstract: Compositions and methods are directed to a sheath core fiber with a core and a sheath that comprises a fluoropolymer. Contemplated sheath materials include PVDF, ECTFE, and ETFE, and may have an apparent shear viscosity equal to or less than the apparent shear viscosity of the core material. Especially contemplated sheaths have a weight of 30% or less of the weight of the fiber. Preferred fibers are spun in a spin pack having a sheath material conduit with a ratio of open volume to sheath material mass flow of less than 0.75 for a fiber with a 30 wt % sheath, of less than 1.15 for a fiber with a 20 wt % sheath, and of less than 2.30 for a fiber with a 10 wt % sheath.
