High performance polyethylene (HPPE) members include at least 5 wt-% of a radiopaque component. The HPPE members are biocompatible and the radiopaque component is a particulate at least partially arranged inside a HPPE filament of the HPPE members. The radiopaque component may have a particle size of at most 1 &#x3bc;m, preferably at most 0.5 &#x3bc;m. Methods of making the HPPE members and various medical devices and repair products which include the HPPE members are also provided.

HPPE member and method of making a HPPE member

Treated HPPE yarns include elemental metal which forms a layer that adheres to the surface of the HPPE yarn and covers at least partly the surface of the HPPE yarn. The elemental metal is deposited onto the outer surface of a HPPE yarn via sputtering, preferably plasma sputtering. Articles comprising the treated HPPE yarn, a device comprising the treated HPPE yarn or the article as well as processes for preparing the treated HPPE yarn or treated HPPE yarn structure or treated HPPE yarn configuration and use of the treated HPPE yarn or an article or a device comprising the treated HPPE yarn for automotive applications, marine applications, aerospace applications, medical applications, defense applications, sports/recreational applications, architectural applications, clothing applications, bottling applications, machinery applications are also disclosed.

Monofilament or multifilament HPPE yarns

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 &#x3bc;m, preferably the radiopaque component has a particle size if at most 0.5 &#x3bc;m. The invention also concerns a method of making the HPPE member and various medical devices and repair products comprising the HPPE member.

The invention relates to a treated HPPE yarn characterized in that the treated HPPE yarn comprises: a porous polyolefin layer that adheres to a surface of a HPPE yarn and covers at least partly the surface of the HPPE yarn; a composition comprising an active agent and which composition is at least partially absorbed within the porous polyolefin layer. The invention further relates to an article comprising the treated HPPE yarn, a device comprising the treated HPPE yarn or the article. The invention also relates to a process for preparing the treated HPPE yarn or treated HPPE yarn structure or treated HPPE yarn configuration and use of the treated HPPE yarn or an article or a device comprising the treated HPPE yarn for automotive applications, marine applications, aerospace applications, medical applications, defense applications, sports/recreational applications, architectural applications, clothing applications, bottling applications, machinery applications.

HPPE yarns

The invention relates to a surgical repair article, comprising a structural member of high performance polyethylene (HPPE) filament(s). The invention also relates to a method of making such a surgical repair article, and to a kit of parts comprising the article. The surgical repair article comprises a structural member of high performance polyethylene (HPPE) filament(s), and a biodegradable coating applied to the surface of the structural member, wherein the coating comprises a sol/gel produced inorganic oxide and a biologically active compound incorporated therein. The article combines high tensile strength, biocompatibility and favorable bioactive compound delivery characteristics.
