(b)(4).Visual examination of the returned device noted the distal tip was fractured.An analysis was performed to investigate the fracture of a ball tip feeler, straight (product code: 275010140, lot no: ty15109).An optical image of the fractured surface shows plastic deformation and a rough appearance across the entire surface indicating the feeler tip underwent a static overload failure.The shaft of the feeler also exhibited plastic deformation with bending.No material defects or other abnormalities were observed in this analysis.A review of the device history record was conducted.No issues were identified during the manufacturing and release of this product that could have contributed to the problem reported by the customer.A trend analysis was conducted.No emerging trends were found requiring further actions.A definitive root cause for the broken ball tip feeler, straight cannot be determined.However, fracture analysis suggests that fractured surface shows plastic deformation and a rough appearance across the entire surface indicating the feeler tip underwent a static overload failure.As there has been no issue identified in the manufacturing or release of the device that could have contributed to the problem reported by the customer and no systemic trends were found, this complaint file will be closed with no further action required.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
