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 Graft Material.

The device can be used in conjunction with the CER-SUB-83N 8 gauge sub chondral access needle.  The access needle creates a working channel into the bone.  The 11 gauge dowel harvesting cannula is 3 cm longer than the access cannula and allows the clinician to remove 3 cm of bone distal to the end of the access cannula.  This bone can be transplanted if obtained from healthy bone, discarded if obtained from an area of necrotic bone, or sent off for histological examination.

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.
