The present invention regards an implant that may be uniquely shaped to
enhance its functionality and that may also be coated with a coating
system that affects its functionality. In one embodiment the implant may
have a first surface that is covered with a filter material, the filter
material being in contact with a catalyst that promotes the decomposition
of Hydrogen Peroxide into Hydrogen and Oxygen. In this and other
embodiments, this filter material may be made from ceramic materials and
may be meso-porous. In another embodiment, the implant may or may not be
coated with this system and may have at least one strut with a tapered
cross-section, the cross-section becoming smaller in area when moving
from a reference point on the inside of the implant to the outside of the
implant.
