Abstract: In a method for impregnating semi-finished fibrous products using resin as the impregnating means, winding or laying the semi-finished fibrous products in a plurality of layers on top of one another onto a receiving carrier is initially performed. Here, lower layers lie close to the receiving carrier, and upper layers lie more remote therefrom. The receiving carrier is configured so as to be permeable to the impregnating means. The impregnating means is then introduced through the receiving carrier into the semi-finished fibrous products, wherein the impregnating means initially permeates the lower layers and then permeates the upper layers of the semi-finished fibrous products.

Abstract: Using porous hollow fiber membranes, systems/methods for continuously synthesizing polymer-coated particles by anti-solvent crystallization are provided. The disclosed systems/methods provide for synthesis of polymer-coated drug particles/crystals from solutions of the polymer and the drug particles in suspension by exposing the solution to an anti-solvent through a porous hollow fiber device. A feed solution of a coating polymer with suspended drug particles can be exposed to an anti-solvent through hollow fiber pores, thereby causing the polymer to precipitate on and coat the drug particles. In addition, a feed solution of a coating polymer with drug in solution can be exposed to an anti-solvent through hollow fiber pores, thereby causing the drug to crystallize from the solution and the polymer to precipitate/coat the drug. Results indicate that a uniformly coated, free-flowing product may be developed in this advantageous porous hollow fiber anti-solvent crystallization method.

Abstract: The present invention is directed to a method for manufacturing a microstructure, the method comprising: (a) placing a viscous composition on a substrate; and (b) applying negative pressure to the viscous composition to induce an extension of the viscous composition, thereby forming a microstructure, and a microstructure manufactured therefor. According to the present invention, a microstructure can be formed without performing a heat treatment by applying a negative pressure. Consequently, it is possible to mount on a microstructure various materials that are sensitive to heat and easily damaged or degenerated. According to the present invention, a microstructure can be manufactured in a non-contacting manner, that is, without being contacted with conventionally used another structure such as a mold or filler.

Abstract: Biocompatible coatings and spin finishes that can be applied to polyhydroxyalkanoate (PHA) polymers, and medical devices made from PHA polymers, have been developed. The coatings impart good lubricity to PHA polymers, particularly to fibers and braids made from these materials, making the coatings ideal for use on medical devices such as PHA braided sutures. The spin finishes can be applied to PHA fibers to facilitate their manufacture, and also for their conversion to other products, including medical textiles. The spin finishes serve to protect multifilament fiber bundles, and keep them intact following extrusion, and also to impart lubricity to the fiber bundles and monofilament fibers so that they are not damaged in subsequent processing steps particularly in textile processing. The coating reduces tissue drag of, for example, braided sutures.
