VEO interbody fusion system uses Zeniva PEEK

65

Solvay Specialty Polymers has announced that Trans1 has commercialised the VEO direct lateral access and interbody fusion system and that this system incorporates a fusion cage implant made from Solvay’s Zenvia PEEK resin.

According to a Solvay press release, the VEO system also features a tubular retractor made of Solvay’s Radel polyphenylsulfone (PPSU) resin for radiolucency and the ability to withstand repeated steam sterilisation.  


TranS1’s VEO is a direct lateral fusion system for the lumbar spine. Its interbody cage is made from Zeniva PEEK rod stock that TranS1 offers in various sizes, including widths of 17mm and 22mm and lengths from 40mm to 60mm. The implant has a large centre channel to allow bone growth through the device, fusing the adjacent bony surfaces of the vertebrae. The press release reported that 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. It is certified to meet the full requirements of the ASTM F2026 standard for PEEK used in implantable surgical devices.


“This is a perfect example of the value Solvay brings with its breadth of products, expanding the options for designers in terms of design flexibility and performance optimisation,” said Shawn Shorrock, global healthcare market manager for Solvay Specialty Polymers. “In addition, the ongoing acceptance of Zeniva PEEK has validated our approach to the spinal market and we’re encouraged by the momentum we’ve generated.”
