Estimating the term…
The invention concerns a high performance polyethylene (HPPE) member comprising at least 5 wt-% of a radiopaque component, the HPPE member is biocompatible and the radiopaque component is a particulate at least partially arranged inside a HPPE filament of the HPPE member. Furthermore, the radiopaque component has a particle size of at most 1 μm, preferably the radiopaque component has a particle size of at most 0.5 μm. The invention also concerns a method of making the HPPE member and various medical devices and repair products comprising the HPPE member.
A high-performance polyethylene (HPPE) multifilament yarn comprising at least one HPPE filament, wherein the yarn has a Young's modulus of at least 30 GPa, an ultimate tensile strength of at least 1.5 GPa, is biocompatible, and comprises at least 15 wt % and less than 60 wt % of a particulate radiopaque component having a particle size of at least 0.05 μm and at most 1 μm, and wherein the radiopaque component is at least partially arranged inside the at least one HPPE filament.
