This report is being amended to reflect changes in sections.Two sets of wire grippers were alleged to insufficiently grip guide wires.There was no resulting harm to the patient and revision surgery was not performed.Surgery was delayed by 15 minutes.The devices were used for treatment.The wire grippers were evaluated via visual examination, dimensional analysis, and functional tests.Visible dents and signs of wear on the pivot hole, strike handle, and teeth of threaded rod are indicative of use over their potential field ages of 6 years 8 months and 3 years 7 months.Review of device history records and inspection reports for both devices indicated that they were manufactured to specifications.Based on the information provided, the probable cause of failure for both devices is wear from use.
