As the individual fibers are dry prior to contact with other fibers, the different contents of the various fiber types do not interact. However, when wetted, the fibers will start to be dissolved, or swell, and the different contents will be released and then interact. For the example of thrombin and fibrinogen, the interaction will initiate the formation of a fibrin coagulum by the cleavage of fibrinogen through the action of thrombin to form fibrin monomers that spontaneously polymerize to form a three dimensional network of fibrin. | 07-11-2013 |
| 20130241105 | PROCESS FOR PRODUCING HIGH-PERFORMANCE POLYMER FIBERS - The present invention relates to a process for the preparation of polymer filaments having a high tensile strength and modulus by extrusion of a solution of a solvent and linear high-molecular weight polymer and subsequent spinning and quenching of the filaments thus formed, wherein after spinning and quenching the as-spun filaments are stretched under contact with steam for removing the solvent from filaments being stretched. | 09-19-2013 |
| 20140035191 | THREE DIMENSIONAL NETTED STRUCTURE - A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded.

| 20140103569 | Method of Manufacturing Continuous Fastener Element - A continuous fastener element including: a coupling head; upper and lower leg portions; and a connecting portion wherein surfaces of the coupling head, the leg portions, and the connecting portion are each formed as a rough surface with a plurality of recesses. Furthermore, a head surface of the coupling head of the continuous fastener element is formed to have an average roughness Ra smaller than that of outer peripheral surfaces of the leg portions. Accordingly, gloss and luster of the continuous fastener element may be easily reduced or removed. Furthermore, when the slide fastener is formed, the resistance between the coupling heads of the left and right continuous fastener elements may be made small and the left and right element rows may smoothly engage with each other or disengage from each other. | 04-17-2014 |
| 20140246802 | Polyhydroxyalkanoate Medical Textiles and Fibers - Absorbable polyester fibers, braids, and surgical meshes with prolonged strength retention have been developed. These devices are preferably derived from biocompatible copolymers or nomopolymers of 4-hydroxybutyrate. These devices provide a wider range of in vivo strength retention properties than are currently available, and could offer additional benefits such as anti-adhesion properties, reduced risks of infection or other post-operative problems resulting from absorption and eventual elimination of the device, and competitive cost. The devices may also be particularly suitable for use in pediatric populations where their absorption should not hinder growth, and provide in all patient populations wound healing with long-term mechanical stability. The devices may additionally he combined with autologous, allogenic and/or xenogenic tissues to provide implants with improved mechanical, biological and handling properties. | 09-04-2014 |
