Abstract:
1. A bioimplant which on implantation is subject to multidirectional translational loads tending to cause displacement of the bioimplant from the site of its implantation, the bioimplant comprising: a single top load bearing surface, the top load bearing surface defined in a first plane and having a plurality of nonuniformly configured protusions extending therefrom and extending along the top load bearing surface in generally a first direction; and a single bottom load bearing surface, the bottom load bearing surface defined in a second plane and having a plurality of nonuniformly configured protrusions extending therefrom and extending along the bottom load bearing surface in one or more directions; wherein in a superimposed view of the first and second planes, the first direction is substantially nonparallel to all of the one or more directions of the protusions extending along the bottom load bearing surface, and the protrusions are substantially nonuniformly shaped and sized, and each protrusion having a different angle relative to each other.
