(b)(6).The instrument was not returned for evaluation due to being discarded.The product that exhibited the failure mode was reproduced using needles and a silicone membrane to substitute as the tissue.By using this set up the, fracture was recreated in the same location.Further investigation of the needle did not reveal any dimensional problems or manufacturing defects for the needle.Analysis of the passer showed that needle track was biased to far to one side.This would allow the needle to come out of it's track and twist.This increased the resistance or force required to "push" the needle through the tissue.This further supports the evidence that the needle is under high compression causing the needle to buckle/break.Review of the dhr found units were released for distribution with no deviation or anomaly.Review of complaint history identified associated complaint and a trend which was addressed through internal controls.The root cause was determined to be associated with failure during design verification, failure to implement appropriate inspection techniques, and incorrect prints from vendor.A summary of the investigation has been sent to the complainant.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.This report is being submitted late as it has been identified in remediation.Multiple mdr reports were filed for this event, please see associated reports:09985.
