Abstract
A surgical implant may include a porous structure with interconnected pores for ingrowth of bone into the porous structure. The porous structure has an arrangement of fibres which are attached to one another, the fibres being arranged in stacked layers. The porous structure has a surface including different regions having different porosities. A method of making the above surgical implant is also described.
Claims18
A surgical implant, comprising:
- a porous structure having interconnected pores configured for ingrowth of bone into the porous structure, wherein the porous structure comprises an arrangement of fibers which are attached to one another, wherein the fibers are arranged in layers, and wherein the layers are stacked;
- and wherein the porous structure includes a surface including a plurality of regions having different porosities, the different porosities being determined by the arrangement of fibers;
- and wherein the porous structure is attached to a dense part, and wherein the surface is disposed opposite the dense part, such that each of the regions having different porosities extend from the surface toward the dense part.
