Additional Manufacturer Narrative

THE DEVICE MALFUNCTION A REVIEW OF THE DEVICE'S RISK FILES DETERMINED THAT THE LIKELIHOOD OF A SIMILAR EVENT (TABLE MOVES DURING A SURGICAL INTERVENTION BECAUSE THE BRAKE¿S JACKING MECHANISM FAILS) LEADING TO A CRITICAL INJURY (MUSCULAR/SKELETAL INJURY) IS IMPROBABLE, THEREFORE, IT CAN BE REASONABLE CONCLUDED THAT IF A SIMILAR EVENT WERE TO RECUR IT WOULD BE UNLIKELY CAUSE OR CONTRIBUTE TO A SERIOUS INJURY OR DEATH. AFTER THE EVENT OCCURRED, THE CUSTOMER CONTINUED TO USE THE DEVICE INVOLVED WITHOUT ANY FURTHER ISSUE. A SERVICE TECHNICIAN FROM A BAXTER AUTHORIZED DISTRIBUTOR IN DENMARK EXCHANGED THE HYDRAULIC UNIT AND THE FLOOR STAMPS IN JULY 2025. THE EXCHANGED PARTS WERE SENT TO THE BAXTER MANUFACTURING PLANT FOR FURTHER ANALYSIS. IN A FIRST INSTANCE THE PARTS WERE INSTALLED IN A DIFFERENT PST 500 SURGICAL TABLE AND TESTS WERE PERFORMED. THE REPORTED FAILURE MODE OF UNINTENDED UN-LOCKING (THE ALLEGED ¿SINKING¿ FROM THE ORIGINAL CUSTOMER REPORT) COULD NOT BE REPRODUCED. THE HYDRAULIC UNIT AND THE FLOOR STAMPS WERE WORKING AS INTENDED. IDENTIFYING THE ROOT CAUSE OF A NON-REPRODUCIBLE FAILURE REQUIRES THOROUGH AND SYSTEMATIC ANALYSIS, THEREFORE BAXTER WAS NOT ABLE TO ESTABLISH A ROOT CAUSE AT THIS TIME AND WILL CONTINUE WITH THE ROOT CAUSE ANALYSIS AND FURTHER TESTING OF THE PARTS INVOLVED IN THE EVENT. THE ALLEGED FAILURE MODE WILL BE MONITORED FURTHER VIA POST-MARKET SURVEILLANCE ACTIVITIES. A FOLLOW-UP WITH THE CUSTOMER CONFIRMED THAT NO INJURY OCCURRED BASED ON THE REPORTED EVENT.
