This invention relates to bioabsorbable fibers, comprising a semicrystalline fiber-forming core polymer and an amorphous sheath polymer, wherein the core polymer and sheath polymer are separately melt extruded and connected to one another through an adhesive bond. The present invention also relates to reinforced composites of the bioabsorbable fibers, and to devices comprising the reinforced composites. The devices are suitable for in vivo implantation. Some embodiments of the present devices can also support high loads, making then useful for fracture fixation and spinal fusion. The invention also relates to methods of making the various materials of the invention.
L'invention a trait à des fibres bioabsorbables qui comportent un polymère central semi-cristallin constituant la fibre et un polymère d'enveloppe amorphe, le polymère central et le polymère d'enveloppe étant extrudés en fusion et connectés l'un à l'autre par collage. La présente invention a également trait à des composites renforcés constitués des fibres bioabsorbables, et à des dispositifs comportant les composites renforcés. Les dispositifs conviennent en vue d'une implantation in vivo. Certains modes de réalisation des dispositifs peuvent également supporter des charges élevées, ce qui les rend utiles pour des fixations de fracture et des fusions de vertèbres. L'invention a également trait à des procédés de fabrication des diverses matières de l'invention.
