Device investigation summary: since the product was not returned for analysis, no product failure analysis can be conducted, and no determination of possible contributing factors could be made.Manufacturing controls: the manufacturing process (from shell fabrication to secondary packaging) was reviewed for foreign matter/ particulate control at mentor irving cmes (controlled manufacturing environment) which includes shell fabrication, main assembly, primary packaging areas, gamma sterilization, and secondary packaging areas.At multiple points of the manufacturing process, devices within the lot are processed to ensure any foreign matter, particulates or contaminants are removed or 100% visually inspected for any defects including foreign matter or particulates and subsequently rejected when identified.All manufacturing areas where the shell or device is exposed to environment is a controlled manufacturing environment (cme).Gowning is required and strictly enforced for all individuals entering designated controlled manufacturing environments (cme) at mentor, whether they are mentor employees, visitors or contractors.The cme garments consist of hair coverings (bouffant and/or hood), frock or jumpsuit, and shoe or boot covers.Sterilization records were also reviewed for product code 350-1640, lot# 223220.Environmental monitoring for viable airborne particulates and surface microbials is routinely performed in each controlled manufacturing environment (cme) on a weekly basis.Review of the environmental monitoring data for viable airborne particulates and surface microbials during the manufacturing of product code 350-1640, lot# 223220 identified all acceptable results in order to release the lot.Non-viable particulates are measured on a quarterly basis.Review of the non-viable particulates data for q204 and q304 (periods before and after the manufacture of product code 350-1640, lot# 223220) were reviewed and no excursions were identified.A root cause failure analysis will not be conducted since the investigation could not confirm that an actual failure of the device to conform to expected performance had occurred.Infection, manifested by swelling, tenderness, pain and fever, may appear in the immediate postoperative period or at any time after insertion of the implant.Infection is a known complication associated with any surgery.The application failure modes and effects analysis (afmea) was reviewed for the defect in question (foreign matter/mold) with hazard risk was determined to be as low as possible (alap), with no further action required.If the complaint device is received in the future, the complaint will be re-opened and additional investigation will be completed.Manufacturer¿s reference number: (b)(4).
