Less wear, tailored imaging, enhanced bone growth

Revolutionizing orthopedic outcomes
Learn how


Devices made from our high performance polymers are proven to offer improved biomechanics and comfort.


PEEK-OPTIMATM features a modulus similar to human bone which reduces stress shielding and leads to improved physiological loading.1


PEEK-OPTIMATM - biocompatibility in conformance with ISO 10993-1 for use in the manufacture of medical devices for long-term implantable orthopedic applications.2


PEEK-OPTIMATM polymer’s superior wear performance offers an alternative load-bearing material to metal designed to address metal ion concerns.3

Peek-optima™ natural

PEEK-OPTIMA™ polymer blends proven performance with superior wear, safety and comfort and has properties that are closer to bone than metal, so there is less stress shielding.1 Since Invibio introduced PEEK-OPTIMA as the first implantable PEEK polymer in 1999, it has earned the confidence and gained the acceptance of the global medical community.
