Medical-grade PEEK: a proven implantable polymer

The PEEK-OPTIMATM family of products is available in a wide variety of forms making it one of the most versatile biomaterial solutions available to medical device designers for long-term implantable solutions.

Medical-grade, biocompatible PEEK polymer materials

Our wide range of biocompatible polymer materials and compounds are each designed to meet the specific and rigorous demands of implantable medical devices. PEEK materials are tailored to offer superior performance in a variety of applications including spine, orthopedic, trauma, dental and specialty devices. Innovative PEEK materials and our in-depth manufacturing knowledge combined with application expertise supports medical device companies to bring leading edge devices to market and open up new areas of growth.

Transformative PEEK implant material for medical applications

human body scheme

Spine & Orthopedics

Our biocompatible PEEK-OPTIMATM polymers are a leading choice for applications including spinal interbody fusion devices & anterior cervical plates


Delivering next generation technologies for fracture fixation and reducing implant failure, our carbon fiber composite trauma solutions are benefiting patients worldwide with a less stiff material compared to metal

Medical devices

Short and long-term implantable solutions for cardiovascular, neurological and connected drug delivery devices such as diabetes management and respiratory devices


Shock absorbing, durable and lightweight biomaterials for restorative and prosthetic dentistry, that offer a more natural dental solution than metals and ceramics


PEEK-OPTIMA™ polymer blends for proven performance with superior wear, safety and comfort. 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.
More than twenty years ago, the biocompatible PEEK-OPTIMATM Natural polymer quickly became the material of choice in interbody fusion and developed a successful clinical track record.  Today, approximately 15 million PEEK-OPTIMA polymer devices are implanted worldwide. This high-performance, implant-grade polymer serves as the foundation for the PEEK-OPTIMA product family.

All the benefits of PEEK-OPTIMATM Natural plus Hydroxyapatite (HA) crystals embedded throughout the material, a well-known osteo-conductive material. Unlike interbody fusion devices that are coated, PEEK-OPTIMATM HA Enhanced devices have hydroxyapatite crystals on all surfaces which results in earlier bone on-growth and greater new bone formation on a fully osteoconductive implant. Key benefits include:

  • Enhanced bone apposition1,
  • Greater new bone formation2
  • Higher quality of new bone bridging2.
PEEK-OPTIMATM Image Contrast offers all the performance advantages of the clinically proven and highly utilized PEEK-OPTIMATM Natural, with one unique difference: it allows for tailored radiolucency that can be optimized for application-specific image guidance and post-operative healing assessment requirements.

A carbon fiber reinforced PEEK polymer compound to increase strength while reducing stress shielding by more closely matching cortical bone stiffness. Short carbon fibers are dispersed within the PEEK-OPTIMATM Natural matrix enhancing mechanical and physical properties for more demanding load-bearing implants and applications. Benefits include3:

  • Fiber-to-matrix bond strength provides higher strength than PEEK-OPTIMA Natural Polymers
  • Bone-like stiffness can reduce stress shielding by more closely matching cortical bone stiffness
  • Extensive history of use in FDA 510(k) cleared, long-term implantable devices 

An innovative composite formed by continuous carbon fibers dispersed within the PEEK-OPTIMA Natural polymer matrix to enhance mechanical strength and stiffness.

Benefits include:

  • Excellent fatigue resistance and structural strength for device longevity4
  • Tailored stiffness for design flexibility4
  • Radiolucent, offering circumferential visibility of the surgical site before and after the procedure.
