Eisertech Achieves FDA Clearance for New Spinal Implants Made of Solvay's Zeniva® PEEK

Thermoplastic Biomaterial Delivers High Performance in Cervical and Lumbar Cages

ALPHARETTA, Ga. - Eisertech LLC, a San Diego, Calif. - based designer and manufacturer of cost-effective spinal implants, has received 510(k) clearance from the U.S. Food & Drug Administration (FDA) for its new cervical cage and lumbar cage implants made of Zeniva® polyetheretherketone (PEEK) rods from Solvay Specialty Polymers USA, LLC. Zeniva® PEEK - part of Solvay's line of Solviva® Biomaterials - has a modulus very close to that of bone plus excellent toughness and fatigue resistance. The FDA clearance was based in part on Solvay's well-developed master access file for Zeniva® PEEK.

The cage systems, made from various sizes of Zeniva® PEEK rods, are hollow so that bone can grow through the device, fusing the adjacent bony surfaces of the vertebrae. "Zeniva® PEEK delivers the high-performance properties that are necessary for a high-precision implant used in cervical spine fusion surgery," said Lukas Eisermann, president of Eisertech.

Zeniva® PEEK offers numerous advantages over metals such as titanium for these intervertebral implantable devices. The material offers many important benefits including biocompatibility, chemical inertness, and a modulus of elasticity that is close to that of bone. Based on biocompatibility testing, Zeniva® PEEK demonstrates no evidence of cytotoxicity, sensitization, irritation, or acute systemic toxicity. It also boasts high strength and stiffness and has radiolucent properties which permit x-ray procedures. Eisertech buys Zeniva® PEEK rod stock directly from Solvay and machines and designs a full range of sizes and configurations.

"We're excited about the commercial success of Zeniva® PEEK in the spinal fusion market," said Shawn Shorrock, global healthcare market manager for Solvay Specialty Polymers. "The ongoing acceptance of Zeniva® PEEK has validated our approach to the spinal market and we're encouraged by the momentum we've generated."

Eisertech's business model is focused on lowering the cost of spinal implants. Eisermann says the company's products can be adopted by surgeons without having to attend a specialty training course, and can be serviced and re-ordered by hospital or surgery center staff via an online store without assistance from an on-site company representative. "This arrangement allows us to significantly streamline our business processes and infrastructure significantly relative to traditional full-service implant manufacturing companies," said Eisermann. "That streamlining shows up as savings which we pass on to our customers."

Zeniva® PEEK and the entire line of thermoplastic Solviva® Biomaterials are manufactured in compliance with the relevant aspects of ISO 13485 and under the relevant aspects of current Good Manufacturing Practices. Solvay's biomaterial manufacturing processes are carefully validated and enhanced controls provide product traceability. In addition, all materials are tested in an accredited lab that is ISO 17025 compliant.

Solvay is currently in active product trials with several major medical device manufacturers using Zeniva® PEEK and other Solviva® Biomaterials.

In addition to Zeniva® PEEK, Solvay's Solviva Biomaterials line includes Proniva® self-reinforced polyphenylene (SRP), one of the world's stiffest and strongest unreinforced thermoplastics that offers exceptional hardness and biocompatibility; Veriva® polyphenylsulfone (PPSU), which provides unsurpassed toughness combined with transparency and excellent biocompatibility; and Eviva® polysulfone (PSU), which offers practical toughness in a strong, transparent polymer. These sterilizable products are available in injection molding and extrusion grades as well as rods and plates for machined components.
