Development of a 3D-printed antimicrobial spinal fusion cage using novel Si3N4-PEEK material to reduce infection-related failures in spinal surgeries, including testing and FDA approval preparation.
Description
This project aims to develop a 3D-printed anti-microbial spinal fusion cage that promotes osseointegration, withstands in vivo loading, and facilitates imaging. The device incorporates a novel Si3N4-PEEK material that combines antimicrobial and osseointegrative properties with strength and elasticity. The project includes biomechanical testing, in vivo fusion property testing, and aims to prepare a 510(k) premarket notification for FDA approval.
