Stryker received one report of an injury to an untrained user that occurred while the untrained user was moving an Airo TruCT unit in reverse. The firm will increase visibility of instructions for users to consider when transporting the unit in reverse by providing labels to be affixed onto the AIRO.
Stryker received a report of a battery fire involving an Airo TruCT unit previously subjected to bypass charging. The firm is notifying customers with units whose battery monitoring systems were bypassed to charge the batteries; the batteries in these units require replacing.
The Tube Current Modulation feature (Modulated Scans) is not working in AIRO systems with software version 2.0.0.0, and operators would not be able to detect this fault until after a scan is completed.
If the tilt-drive motor has an intermittent connection or broken encoder or sensor wire there is a risk of unintended or unpredictable device motion while the CT system is homing the axis at startup or preparing for a scan.
There is a risk that during the transfer of an image and navigation data to the Brainlab Curve Image Guided Surgery Navigation System after a CT scan, an error may occur, causing either no navigation data or incorrect navigation data being transferred to the curve.
