Funder Nivalon Medical Technologies has successfully developed the world’s first fully patient-specific, motion-preserving spinal implant. Designed entirely without metal, the EvoFlex implant leverages AI-driven design and advanced ceramic 3D-printing technology to create a truly personalized solution for spinal care.
The implant features a zirconia-toughened alumina (ZTA) ceramic architecture engineered to behave similarly to organic bone, paired with a flexible elastomeric core that replicates natural spinal motion. Unlike traditional spinal implants, typically manufactured in fixed sizes using metal alloys, the EvoFlex implant is custom-designed from each patient’s CT imaging data and 3D-printed to precisely match their unique anatomy. By eliminating metal alloys, Nivalon Medical addresses common complications associated with conventional implants, including corrosion, ion release, stiffness mismatch, and imaging interference. This patient-specific, metal-free approach enables improved biomechanical compatibility while preserving natural spinal movement.
Testing was conducted at the Osman Lab, by the University of South Florida’s (USF) NeuBac Laboratory, under the direction of Dr. Nathan Schilaty. EvoFlex implants were evaluated using a Dynamic Investigation of Spine Characteristics (DISC) simulator under six degrees of freedom motion and physiologic spinal loading. Results demonstrated stiffness curves and motion profiles closely replicating natural human spinal behavior, confirming both motion preservation and mechanical articulation. The implant has been clinically validated through independent biomechanical, mechanical, biological, and surgical testing. The first human procedures utilizing the EvoFlex implant, including participation by Nivalon Medical Co-Founder and CEO Todd Hodrinsky, are planned for 2026.
