EnBIO
today launched its OsteoZip
TM surface, which has been designed to
enhance the osteointegration and early bone fixation of orthopedic
implants into host bone tissue. OsteoZip is a revolutionary new
hydroxyapatite (HA) surface that is ideal for orthopedic and dental
implants. Applied and enabled by EnBIO's CoBlast
TM surface modification
process, OsteoZip heralds a new era of functional surfaces for
orthopedic implants. The CoBlast process is non-complex, room
temperature and requires no wet chemistry, providing orthopedic implant
OEMs with a state-of-the-art surface at a competitive cost. The CoBlast
process is in fact a novel variation of grit-blasting-a well practiced
process in the medical device industry-and the CoBlast processing
equipment is essentially a modified version of standard grit blasting
equipment.

EnBIO's
in-vitro and in-vivo testing shows that the OsteoZip surface exhibits
superior bone fixation and faster osteointegration than other standard
orthopedic implant surfaces such as roughened, RBM, and plasma sprayed
HA. This enhanced performance is due to the fact that the HA on the
OsteoZip surface is ~100% crystalline (HA is not heated during the
deposition process) and due to the thin HA layer (~10µm). This thin
layer also means that the HA will not shear or delaminate,
counteracting the well known problem of traditional HA coatings
(applied via plasma spraying [1-3]). It is expected that this will also result in better long term stability relative to traditional HA coatings. EnBIO's
business model is twofold. Fundamentally, the CoBlast technology will
be licensed to orthopedic OEMs. EnBIO will work with OEMs to set up and
optimize the OsteoZip surface using modified grit blasting equipment.
Alternatively, EnBIO can provide a coating service (via established
implant coating partners) for any prospective customer who does not
wish to set up a CoBlast coating capability in their own facility. EnBIO
has filed an OsteoZip master file with the FDA and is also filing a
510K for an OsteoZip coated screw product which can then be used a
predicate for other applicants.
