Bone Funnel. The Integra Expandable IBD System consists of lumbar interbody fusion devices manufactured from PEEK-OPTIMA® LT1 (ASYM F2026), titanium (Ti-6AI-4V ELI per ASTM F136) and cobalt chromium (Co-28Cr-6Mo per ASTM F1537) materials, with radiopaque tantalum markers (ASTM F560). These implants are generally box shaped with surface teeth and a central channel to be filled with autogenous bone graft.
A device designed to deliver bone graft filling material (autologous, allogeneic, xenogeneic, or synthetic) during an orthopaedic procedure to enable the filling of bone gaps intended to be fused. It is a funnel-shaped device; the funnel being bowl-shaped with the ability to hold back the filling material depending upon the angle of tilt applied by the surgeon, and a long, thin tube that can be inserted into the site to be filled, e.g., a cancellous bone graft being discharged into the posterior disc space of a vertebra. An orthopaedic graft inserter can be pushed down the funnel tube to press the graft material into the site. This is a reusable device.
