Centinel Spine

Centinel Spine develops, tests and markets new and innovative products with an eye toward making spinal fusion surgery easier for both surgeon and patient alike. Centinel Spine derived its name from the “Sentinel Sign” — the radiographic confirmation of a successful fusion anterior to the interbody device. Founded in 1990, Raymedica became the recognized leader in nucleus replacement devices through the development of revolutionary products like the PDN and HydraFlex. Throughout its 18-year history, the company developed pioneering technologies and surgical approaches to the spine that helped thousands of patients restore function, reduce back pain, and avoid more invasive procedures. Raymedica was also the first company to develop a system for the Antero-Lateral Trans-Psoas Approach (ALPA)—implanting the PDN device via lateral access to the spine.
