Abstract: A mobile safety fall arrest cart is provided. The mobile safety fall arrest cart is configured to move along an edge of an elevated surface as a worker works along the edge. The worker is connected to the cart with a safety line. If the worker falls from the elevated surface, the weight of the worker causes a spike assembly to move from a stowed configuration to a deployed configuration. In the deployed configuration, a spike member engages the elevated surface so as to assist in arresting the worker's fall.

Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a desirable combination of physical and chemical properties. Crosslinked bulk materials are heated to a compression deformable temperature, and pressure is applied to change a transverse dimension of the material. After cooling and stress relieving, a treated bulk material is obtained that has enhanced tensile strength in the axial direction orthogonal to the dimension change. In preferred embodiments, medical implant bearing materials are machined from the treated bulk material with the in vivo load bearing axis substantially parallel or coincident with the axial direction of the treated bulk material.

Abstract: A prosthetic bearing component (10) comprising a bearing surface (40), wherein in use one or more openings (20) are provided on the bearing surface (40) and wherein the one or more openings (20) are suitable for receiving one or more attachment means (30) to secure the prosthetic bearing component (10) in place.

Abstract: Composite acetabular components, and methods of making and using same, are described. The composites consist of a ceramic liner having a backing of plastic material, such as but not limited to ultra high molecular weight polyethylene (UHMWPE), molded around the ceramic liner. The back surface of the ceramic liner is textured to enhance the mechanical bonding strength of the plastic backing to the textured ceramic liner during the molding process.

Abstract: A work hardened articulating surface for anatomical prosthetics. Articulating surfaces of prosthetics are work hardened to decrease the wear and increase the longevity of the prosthetic after implantation. The articulating surface can be hardened in any number of ways, for example the articulating surface can be formed from stock material that has been work hardened throughout or the articulating surface can be work hardened prior to final finishing of the prosthetic component. Regardless, the hardened articulating surface reduces wear after implantation while eliminating the need for a separate bearing component.

Abstract: An acetabular prosthesis including a ceramic shell having multiple layers and a polymer liner formed integrally with the shell. The acetabular prosthesis shell is formed of a ceramic wherein several layers with varying porosities and thicknesses are sintered together to form a unitary structure. A polymer inner liner forms a bearing within the shell to receive the ball of a femur or femur prosthesis. The polymer liner is formed in the ceramic shell and includes a plurality of portions which interdigitate into the pores of the inner porous layer of the ceramic shell.
