The following fields have been updated due to additional information: d.9.Device available for eval?: yes.D.9.Returned to manufacturer on: 08-feb-2023.H.6.Investigation summary: to aid in the investigation of this issue, five (5) physical samples were returned for evaluation by our quality engineer team.Four (4) of the samples were still in their unit packages and one (1) sample appeared to have been used.A silicone distribution test was performed on all of the returned samples.All of the samples tested correctly for silicone distribution.The syringe that appeared used showed correct silicone distribution; however, a lighter quantity was observed, which could have contributed to resistance when moving the plunger; therefore, the reported issue is confirmed.A device history record review was completed for provided material number 306575 and lot number 2263053.The review did not reveal any quality notifications during the production process; however, there were two (2) second samplings that could have potentially been related to this reported incident.Although all inspections were found to be within specifications, a corrective maintenance was carried out on the fill machines where the nozzle and the sleeve pump were replaced.It has been determined that the defective sample was most likely manufactured somewhere between the second samplings during the production process.Based on the preventive measures in place, we believe this was an isolated incident with an unlikely chance of recurrence.At this time, further action has not been determined necessary.Our quality team will continue to closely monitor the manufacturing process for signs of this potential defect and any emerging trends.H3.Other text : see h10.
