Abstract
An implantable article includes a textured bone engaging surface having a surface texture pattern formed by a plurality of furrows separated by ridges that are integral with the base material from which the article is formed. The furrows are formed by ablating in the surface a series of intersecting holes. The side walls of the furrows have scalloped edges. The ablating energy can be applied by techniques such as laser ablation and hydrojet ablation.
Claims15
A process for forming a textured surface upon an implantable prosthesis, comprising the steps of:
- providing an implantable metallic body having a bone-engaging surface;
- providing an ablation apparatus able to deliver energy to the body for ablating at least a portion of the metallic body;
- and
- ablating a portion of the bone-engaging surface of the body in a predetermined pattern to form a plurality of furrows therein, each furrow being separated by a continuous raised ridge that is integral with the bone-engaging surface.
