Additional information is provided in sections d.9, h.3, h.6 and h.11.One opened polymer the irrigation aspiration (i/a) bimanual set in a tray in a blister was received for the report of an aspiration issue.The sample was visually inspected and found to be non-conforming with the purple aspiration handpiece observed to have foreign material that was clear and orange/brown in color at the port hole of the i/a tip, the head of i/a tip and on the metal cannula below the gray over mold i/a tip.The particle analysis found the foreign material to most closely match viscoelastic.A review of the device history record traceable to the reported lot number, indicates that the reported product was processed and released according to the reported product¿s acceptance criteria.The investigation conducted a non-conformance review of the reported lot number.No deviations were identified and all corresponding production release specifications defined in the device master record were met.The particle analysis found the foreign material to most closely match viscoelastic.Viscoelastic is not a material that is used in the manufacturing process of the disposable handpiece.How and when the viscoelastic got on it the irrigation aspiration (i/a) tip cannot be determined from this evaluation and a root cause cannot be determined for the complaint as described by the customer.Based on the evaluation of the information received, the investigation was unable to identify the root cause or origin of the reported event.Additionally, no manufacturing-related deficiencies were found that potentially could have contributed to the complaint.As the root cause and its origin are inconclusive, further investigative or manufacturing actions are not warranted at this time.All handpieces are 100% visually inspected prior to being released from the manufacturing facility.Receipt of additional relevant information or supporting materials will prompt a re-evaluation of the complaint investigation.Complaint data for all manufacturer products is reviewed monthly to monitor for adverse trends.During the last review, no adverse trends were observed for the reported product and event combination.Quality assurance has reviewed this complaint and will continue to monitor data for evidence of adverse trending and take further action, as appropriate.No further action warranted at this time.The manufacturer internal reference number is: (b)(4).
