Abstract
Composite fibrous constructs are made of combinations of inorganic-organic hybrid monofilament or multifilament yarns containing at least 6 weight percent of inorganic micro-/nanoparticles and organic monofilament or multifilament yarn with typical examples of the hybrid yarn matrix made of absorbable or non-absorbable thermoplastic polymers and final constructs being in the form of knitted or woven meshes and braided ligatures intended to perform under specific mechanically, biologically, and/or radiologically related functions.
Claims6
A composite fibrous construct comprising a braid of a hybrid yarn and at least one other multifilament yarn of an organic thermoplastic polymer, the braid comprising a core comprising the hybrid yarn and a sheath made of the at least one other multifilament yarn, the hybrid yarn comprising a monofilament and comprising an inorganic-organic hybrid melt-extruded yarn, the hybrid yarn comprising an organic thermoplastic polymeric matrix component and at least about 6 percent by weight of at least one type of inorganic micro-/nanoparticles dispersed in the polymeric matrix, wherein the inorganic micro-/nanoparticles comprises barium sulfate and the organic thermoplastic polymeric matrix of the hybrid yarn comprises at least one polymer selected from the group consisting of poly-ε-caprolactone, Nylon 6, Nylon 12, and an absorbable segmented polyester derived from one of glycolide and l-lactide and at least one additional cyclic monomer.
A composite fibrous construct comprising a knitted or woven mesh for hernia repair comprising a hybrid yarn and at least one other multifilament yarn of an organic polymer, the hybrid yarn comprising a multifilament yarn and comprising at least one type of inorganic-organic hybrid melt-extruded yarn, the hybrid yarn comprising an organic thermoplastic polymeric matrix component and at least about 6 percent by weight of at least one type of inorganic micro-/nanoparticles dispersed in the polymeric matrix, the hybrid yarn having a structure selected from monofilament yarns and multifilament yarns, the mesh further comprising a lubricious coating.
