    (B)(4). G3: REPORT SOURCE, FOREIGN - EVENT OCCURRED IN GERMANY. PRODUCTS HAVE BEEN RETURNED TO BIOMET UK LTD FOR EVALUATION AND FORWARDED TO THE COMPLAINTS PRODUCT EVALUATION ENGINEER FOR INVESTIGATION. THE EVENT REPORTS THAT IT WAS IDENTIFIED THAT THAT THE TOP FOAM WAS ADHERED TO THE TYVEK LID, WHICH RESULTED IN THE IMPLANT BEING PROJECTED INTO THE FLOOR. THIS EVENT OCCURRED DURING SURGERY. A NON-CLINICALLY SIGNIFICANT (5MINS) DELAY TO SURGERY WAS REPORTED. THE SURGERY WAS COMPLETED WITH AN ALTERNATIVE IMPLANT WITH THE SAME ITEM NUMBER. THE COMPLAINT HAS BEEN CONFIRMED FOLLOWING REVIEW OF THE RETURNED PACKAGING, WHICH HAS EVIDENCE TO SUGGEST THAT THE TOP FOAM WAS ADHERED TO THE TYVEK LID (TRANSFER OF MATERIAL BETWEEN THE TOP FOAM AND THE TYVEK LID). A REVIEW OF THE DEVICE HISTORY RECORDS DID NOT IDENTIFY ANY DISCREPANCIES THAT WOULD HAVE CONTRIBUTED TO THE REPORTED EVENT. A COMPLAINT HISTORY REVIEW IDENTIFIED 3 SIMILAR COMPLAINTS FOR THE SAME ITEM NUMBER. A COMPLAINT HISTORY REVIEW IDENTIFIED NO SIMILAR COMPLAINTS FOR THE SAME LOT NUMBER. THE REPORTED EVENT IS NOT RELATED TO A COMBINATION OF PRODUCTS; THEREFORE, A COMPATIBILITY REVIEW IS NOT APPLICABLE. THE IFU PROVIDED WITH THE DEVICE STATES TO CHECK THE PACKAGING FOR DAMAGE BEFORE USE. THE LIKELY CONDITION OF THE DEVICE WHEN IT LEFT ZIMMER BIOMET IS NON-CONFORMING TO SPECIFICATION. THE CORRECT PACKAGING MATERIALS AND SEALING METHODS HAVE BEEN USED. THE LIKELY CAUSE OF THE REPORTED EVENT IS NOT ENOUGH CLEARANCE BETWEEN THE TOP FOAM AND THE TYVEK LID DURING THE HEAT SEALING PROCESS. THIS CAUSES UNINTENDED HEAT TRANSFERS BETWEEN THE TOP FOAM AND THE TYVEK LID, RESULTING IN ADHESION. THE INDENT IN THE TOP FOAM (WHICH HAVE BEEN CAUSED BY COMPRESSION FROM THE DEVICE) FURTHER INDICATE THAT THE SPACE WITHIN THE BLISTER WOULD HAVE BEEN LIMITED. RISK ASSESSMENT: THE EVENT REPORTS THAT IT WAS IDENTIFIED THAT THAT THE TOP FOAM WAS ADHERED TO THE TYVEK LID, WHICH RESULTED IN THE IMPLANT BEING PROJECTED INTO THE FLOOR. RISK MANAGEMENT FILE DOCUMENTS THE ESTIMATED RESIDUAL RISK ASSOCIATED WITH THE REPORTED EVENT. THIS EVENT OCCURRED DURING SURGERY. A NON-CLINICALLY SIGNIFICANT DELAY (30MINS +) TO SURGERY WAS REPORTED WHICH GIVES A SEVERITY SCORE OF 2. THIS DEVICE IS USED FOR TREATMENT. IN ORDER TO CALCULATE THE OCCURRENCE RATE, SALES AND COMPLAINT DATA FOR THIS ITEM NUMBER HAVE BEEN OBTAINED, AND ARE ATTACHED FOR A PERIOD OF THE LAST 3 YEARS PRIOR TO NOTIFICATION DATE, BEING JUN 9, 2020. SALES (JUL 2017 TO JUN 2020) (MOST UP TO DATE SALES DATA) = 3,520,350. 56 COMPLAINTS WERE IDENTIFIED FOR THIS ITEM NUMBER INCLUDING (B)(4). THEREFORE, THE CALCULATED OCCURRENCE RATE IS 56:3,520,350 = 1:62,863. THIS GIVES AN OCCURRENCE SCORE OF 1. THE OVERALL RISK SCORE IS NEGLIGIBLE. ISSUE EVALUATION (B)(4) HAS BEEN RAISED TO FURTHER INVESTIGATE THIS ISSUE. HEALTH HAZARD EVALUATION (B)(4) HAS BEEN RAISED TO ASSESS THE RISK OF PRODUCT WHICH MAY EXHIBIT THE ISSUE IN THE FIELD. THIS HHE RESULTED IN A NO FIELD SAFETY CORRECTIVE ACTION DECISION. THERE HAS BEEN NO INCREASE IN SEVERITY OR OCCURRENCE SINCE THIS HHE WAS COMPLETED. IF ANY ADDITIONAL INFORMATION BECOMES AVAILABLE, THEN THE COMPLAINT WILL BE REOPENED AND INVESTIGATED THOROUGHLY.
