Manufacturer Narrative

(b)(4).Complaint summary: the complaint states, it was reported that the foam stuck to implant.This event did not occur during surgery.No patient involvement.On visual inspection it can be confirmed that the top foam has adhered to the tyvek lid.Dimensional check of foams confirms compliance to specification.The packaging does not function as designed as the foam should not adhere to the tyvek lid.The complaint is related to the functional performance of the device as it provides protection and contributes to the sterile barrier.The most likely root cause is that the top foam had stuck to the lid when the blister was sealed due to the implant being too snug in the blister and causing the top foam to bulge.If the packaging configuration of the product does not allow a gap between the foam and the coated lid, the lid could get stuck to the foam during sealing process.The thickness of the top foam has been changed, which in turn increases the gap between the top foam and tyvek lid, therefore reducing the probability that the top foam will adhere to the tyvek lid during the sealing process.This change was implemented following the manufacture of the lot number in this complaint.Issue evaluation ie-11839 has previously been raised for a similar reported event, and resulted in a correction to change to the packaging configuration for the item number within this complaint.Health hazard evaluation hhe-2020-00082 was raised to assess the risk of the top foam adhering to the tyvek lid.This hhe resulted in a no field action recommendation.From the information currently available, there is no evidence to suggest that the product left the company non-conforming to specification at the time of manufacture or regulatory compliance.No further actions are deemed necessary at this time.The hazard and reported harm are covered by the risk file and the severity/occurrence and the risk scores are within acceptable limits.The risk is deemed as low.Capa: no corrective or preventive action required at this time.If any further information is found which would change or alter any conclusions or information, a supplemental will be submitted accordingly.Zimmer biomet will continue to monitor for trends.
