Abstract
A bone implantable medical device made from a biocompatible material, preferably comprising titania or zirconia, has at least a portion of its surface modified to facilitate improved integration with bone. The implantable device may incorporate a surface infused with osteoinductive agent and/or may incorporate holes loaded with a therapeutic agent. The infused surface and/or the holes may be patterned to determine the distribution of and amount of osteoinductive agent and/or therapeutic agent incorporated. The rate of release or elution profile of the therapeutic agent may be controlled. Methods for producing such a bone implantable medical device are also disclosed and employ the use of ion beam irradiation, preferably gas cluster ion beam irradiation for improving bone integration.
