The CER-BN-84 is a bone dowel harvesting device that has an 8 gauge cannula and is designed to be powered by a drill. This device allows the capture of living autogenous bone. The initial stylet is used to penetrate the cortical bone. A second shorter stylet is then used to advance the cannula to capture the core sample. The device can be directed at various angles to the initial trajectory to allow for multiple dowels to be taken. This device is often used in conjunction with the Cervos Bone Marrow Aspiration Devices and CellFuse Graft Material. Combining marrow aspirate with autogenous bone and a graft extender allows clinicians to fill boney defects using the patient’s own cells as the engine for bone healing. The combination of all three provide cells, signals and a scaffold; the building blocks for repairing bone.
