New technology provides surgeons with MIS solution for autologous bone capture

DENVER — Feb. 21, 2017 — TranS1®, a medical device company focused on breakthrough spine solutions that minimize tissue trauma, today announced the release of the Capital Bone Graft Harvester, a new technology that allows for fast, reliable, and reproducible harvesting of autograft material from the iliac crest.

“Cancellous bone from the iliac crest is the gold standard for fusion,” said Jeff Schell, President and CEO of TranS1. “The innovative design of the Capital Bone Graft Harvester is intended to solve the deficiencies with traditional iliac crest harvesting approaches and provide surgeons a reproducible MIS autograft solution for use in spine procedures.”

Unlike the traditional open approach, the Capital Bone Graft Harvester allows access to the iliac crest with a one centimeter tissue access dilator. All grafting is performed through that opening. The unique construction of the instrumentation creates access for the capture of bone by utilizing ridges within the tube internal diameter. Shaft fenestration facilitates bone drilling and capture while providing ease of autograft ejection. The device also extracts the graft dowel while shielding surrounding tissue. The iliac crest is targeted using a true anterior posterior fluoroscopic image. Based on surgeon preference, the iliac crest may be accessed from a lateral or prone patient position.

The result, unlike other bone graft substitutes, is a natural sample of the patients’ own bone that can be used in a fusion surgery and contains osteoinductive, osteoconductive, and osteogenic properties. The Capital Bone Graft Harvester is one of several technologies TranS1 has released over the past six months. The company offers a full suite of MIS solutions for spine to compliment its flagship, the AxiaLIF+® System for pre-sacral interbody fusion. The Capital Bone Graft Harvester is patent pending and is currently available on the market.
