Additional manufacturing narrative: during visual analysis, the particulate appeared to extend through the entire width of the seal.The portion of the seal with the embedded fiber was examined using a digital microscope.The lateral view of the seal edge was assessed.The fiber was visible in this cross sectional view indicating that the fiber did extend through the entire width of the seal.The fiber measured 58 micrometers (0.058mm) in width.The full length of the fiber could not be visualized under the microscope; therefore, the length was estimated using a calibrated ruler and found to be approximately 25mm.The total area of the fiber was approximately 1.45 mm squared.Functional testing included peel testing to evaluate the pouch for seal strength.The pouch was peel-tested per the specifications.The seal strength was found to be conforming and unaffected by the presence of the fiber.The fiber was lost during the peel test and consequently no ftir analysis was able to be performed.Based on the individual appearance of the fiber, an analysis was run against the database to determine the possible composition.It was determined that the particulate was most likely a hair.Complaint observation was confirmed.Manufacturing records were reviewed and no non-conformities were recorded that would have contributed to this event.The side seal in which the particulate was found was sealed at the supplier.This indicates the possible root cause was related to supplier processes.Quality indicator review revealed that this nonconformance was an isolated event.Product risk assessment determined the sterility of the device contained within the pouch could not be ensured; therefore, systemic infection or endocarditis may result if the device was used.Corrective actions are being addressed.Edwards will continue to review and monitor all events and if action is required, appropriate investigation will be performed.
