Minimally Invasive Harvester Collects Autologous Bone

A novel surgical instrument harvests autologous bone graft and bone marrow for use in a range of spine and orthopedic procedures.

The Avitus Bone Harvester is a manual instrument that cuts cancellous bone by actuation of a cutting tip in the cap, connected a barbed nozzle that connects via a standard-sized suction tubing to a vacuum source. When actuated in bone, the cutting tip carves, scrapes, and cuts cancellous bone and collects the bone graft inside the handle. The vacuum suction then pulls the bone and bone marrow from the cutting tip and into a bone reservoir. The cap also contains a filter that prevents material from escaping into the suction system by utilizing a physical sieve that keeps bone particulate in the handle.

After harvesting, the bone graft can be retrieved for use as an autograft, which is considered the gold standard of bone graft material due to superior regenerative characteristics, including osteoconduction, osteoinduction, and osteogenesis. Autografts can also provide significant cost savings compared to bone graft substitutes, and eliminate the risk of disease transmission as it is harvested from the patient's own body. The Avitus Bone Harvester is a product of Avitus Orthopaedics (Farmington, CT, USA), and has been approved by the U.S Food and Drug Administration (FDA).

“Autograft is regarded as the gold standard bone graft material; our technology has the potential to mitigate the harvesting challenges associated with autograft and provide a cost effective solution for surgeons using this bone graft option,” said Neil Shah, CEO of Avitus Orthopaedics. “This validates the need for a streamlined way to obtain significant volumes of cancellous autograft and bone marrow.”
