Zavation Medical Products, LLC has pioneered an innovative expandable intervertebral implant designed to enhance spinal fusion procedures. This state-of-the-art implant addresses the challenges of spinal degeneration by offering a dynamic solution that expands within the intervertebral space, optimizing stability and support.

At the heart of this invention is an advanced wedge mechanism that facilitates controlled expansion. The implant consists of an upper and lower body portion connected by a multi-tiered wedge system, allowing for precise height adjustment. The actuator, strategically positioned between the wedge and nose member, enables seamless translation of the wedge, effectively increasing the implant’s height. This unique design ensures a tailored fit within the intervertebral space, minimizing complications and enhancing patient outcomes.

The inclusion of dovetail connections in both the wedge and nose member provides structural integrity while permitting smooth expansion. Additionally, the implant features a bone graft window, allowing for enhanced fusion potential by facilitating bone growth through the device. The corrugated surface of the implant further promotes stability by improving contact with vertebral endplates, reducing the risk of migration or subsidence.

Designed for surgical efficiency, the implant’s actuator connects seamlessly with an insertion tool, streamlining implantation and expansion. This innovative mechanism allows surgeons to achieve optimal spinal alignment with minimal invasiveness. A frictional bearing within the actuator adds resistance, ensuring controlled movement and precision during expansion.

By combining precision engineering with patient-centric design, Zavation’s expandable intervertebral implant represents a significant advancement in spinal surgery. This innovation offers improved fusion potential, enhanced stability, and a more adaptable approach to treating degenerative spinal conditions. With its novel expansion mechanism and integration-friendly features, the implant sets a new benchmark for interbody fusion technology.
