Disclosed herein is a medical implant component comprising a composite biotextile comprising i) a polyolefin fiber construct comprising at least one strand, the at least A strand having a denier of 2 dtex-250 dtex, a tensile strength of at least 10 cN/dtex and comprising high molar mass polyolefin fibers; and ii) a coating comprising a biocompatible and biostable polyurethane elastomer , the polyurethane elastomer contains polysiloxane in the soft segment and/or has at least one hydrophobic end group; wherein the polyurethane coating has been applied to at least a part of the surface of the fiber structure, and based on the amount of the composite biotextile It is present in an amount of 2.5 mass %‑90 mass %. This composite biotextile of at least one strand, such as a partially coated woven fabric, shows an advantageous combination of good biocompatibility, especially hemocompatibility, high strength and flexibility, and laser cutability; thus Allows fabric pieces to be produced with well-defined regular edges with high seam retention strength. The invention also provides a method for manufacturing the composite biotextile. Further embodiments relate to the use of such biotextiles in medical implant components for implantable medical devices and the use of such medical implant components in the manufacture of implantable medical devices such as in orthopedic applications and cardiovascular implants use in things. Other embodiments include such medical devices or implants comprising said medical implant components. |
