  • FIBER REINFORCED COMPOSITIONS AND METHODS OF MANUFACTURE FOR MEDICAL DEVICE APPLICATIONS
    Publication number: 20220409778
    Abstract: The present invention is directed to compositions containing polymer matrix, fiber and/or additives which are suitable for load bearing applications for medical devices. The matrix can be formed from a group of polymers which resorb inside the body after implantation. These compositions contain reinforcing fibers that are incorporated into a resorbable polymer matrix to improve properties such as mechanical. The reinforcing fibers can be resorbable, non-resorbable, natural, or metallic. Additives can be incorporated into the matrix material or the fibers or both to provide a secondary effect. These additives can be bioceramics to provide an osteoconductive effect; antimicrobial particles such as silver; coloring agents, and radiopaque additives to make the implants visible under fluoroscopy. The additives may also contribute to improve mechanical properties.

    Abstract: A process can be used for preparing a polymer coated hard-shell capsule, filled with a fill containing a biologically active ingredient. The hard-shell capsule contains a body and a cap, and in a closed state, the cap overlaps the body either in a pre-locked state or in a final-locked state. The material of the body and the cap contains an ethyl-, methyl-, or propyl-ether of cellulose, starch, or pullulan. The hard-shell capsule is coated with a coating layer that covers the hard-shell capsule in the pre-locked state. The coating layer contains one or more (meth)acrylate copolymers, where the coating layer is present in an amount of about 1 to 5.8 mg/cm2. The process involves providing the polymer-coated hard-shell capsule in the pre-locked state to a capsule-filling machine, separating the body and the cap, filling the body with the fill, and rejoining the body and the cap in the final-locked state.
