Evonik announced the first U.S. surgeries involving a spinal implant made from Evonik’s VESTAKEEP i4 3DF PEEK filament biomaterial. Created by medical device company Curiteva, the implant is FDA-cleared and reported to be the world’s first 3D-printed, fully interconnected porous polyether ether ketone (PEEK) implanted structure of its kind for commercial use.
Designed especially for use in additive manufacturing processes, Evonik’s VESTAKEEP i4 3DF comes in filament form and meets the requirements of ASTM F2026, which is the standard for PEEK polymers approved for use in surgical implant applications. It is the world’s first 3D-printable filament to meet this requirement for medical use.
Marc Knebel, head of Evonik’s Medical Devices & Systems market segment, said, “Innovative developments like our VESTAKEEP i4 3DF PEEK filaments are designed for the utmost biocompatibility, biostability and x-ray transparency – making them excellent materials for orthopedic and maxillofacial surgery.”
