Abstract
The present invention relates to biomaterials for use in surgical implants. The biomaterial can include micropatterns; such as microgrooves and microfeatures such as pores, pits or slits on the surface of the biomaterial. The micropattern can be parallel microgrooves capable of influencing the orientation and alignment of cells proliferating on the surface of the biomaterial. The microfeatures enable tissue ingrowth into the biomaterial and may extend through all or part of the biomaterial, allowing the rapid integration of the implant into the tissue.
