Abstract
A medical device generally includes a structural member having a surface wherein at least a portion of the surface is coated with a nanostructured material to a thickness of at least about 25 micrometers, and wherein the nanostructured material comprises a ceramic, ceramic composite, ceramic metal composite, or a combination comprising at least one of the foregoing. The implants have increased service lifetimes owing in part to improved wear and abrasion resistance, and may be useful for partial or full replacement of articulating and flexible hinge joints.
Claims52
A medical device, comprising a structural member having a surface wherein at least a portion of the surface is coated with a nanostructured material to a thickness of at least about 25 micrometers, and wherein the nanostructured material comprises a ceramic, ceramic composite, ceramic metal composite, or a combination comprising at least one of the foregoing.
A medical device, comprising a first structural member having a first surface and a second structural member having a second surface, wherein at least a portion of one or both of the first and second surfaces is coated with a nanostructured material to a thickness of at least about 25 micrometers.
A method, comprising surgically implanting a medical device comprising a structural member having a surface, wherein at least a portion of the surface is coated with a nanostructured material to a thickness of at least about 25 micrometers, and wherein the nanostructured material comprises a ceramic, ceramic composite, ceramic metal composite, or a combination comprising at least one of the foregoing.
A method of making a medical device, comprising coating at least a portion of at least one surface of the medical device with a film of a nanostructured material having a thickness of at least about 25 micrometers.
