AI overview

Updated

Circinus Medical Technology, LLC, which operates under the Bolt Navigation brand, designs and manufactures a handheld surgical navigation system for spine surgery. Its Bolt Navigation System uses gyroscope-on-chip technology and an iOS device to guide pedicle screw placement in open and minimally invasive posterior thoracolumbar and sacral procedures. The system received FDA 510(k) clearance in December 2022 and is sold on a zero-capital subscription model rather than as a capital purchase. The company was founded in 2019 and is based in Concord, Massachusetts.

What sets it apart

A near-zero-footprint handheld navigation unit that works with standard pre-op CT/MRI and intraoperative X-ray instead of requiring an O-arm or dedicated navigation cart, is compatible with virtually any pedicle screw system, and is delivered as a maintenance-free subscription instead of a capital equipment purchase.
