The following fields were updated due to additional information: d10: device available for eval yes.D10: returned to manufacturer on: 2022-03-22.H6: investigation summary: our quality engineer inspected the sample and photographs submitted for evaluation.Bd received one standalone q-syte along with a 24g x 0.75in.Nexiva product label from lot number 1155068.Additionally, five photos were received for investigation.A gross visual inspection of the returned unit found that the septum was pushed in.The reported issue was confirmed.This was physical/mechanical evidence to confirm and support a manufacturing process related issue for the reported defect relating to insufficient adhesive.Microscopic inspection of the q-syte found that adhesive was not uniformly present on the rim of the q-syte top body.Additionally, the bottom side of the top disk had no adhesive.These observations indicate a possibility of inadequate bond at time of manufacture.No damage to the body of the device was noted, making insufficient adhesive the most likely root cause of the reported defect.During manufacturing, low bond strength (or insufficient adhesive), septum misorientation, damage to the top body of the q-syte, and damaged tooling may result in the septum being pushed in.Our operator-controlled checks for bond strength and septum damage are performed to mitigate the risk from this type of defect.Additionally, preventative maintenance (pm) is performed to ensure tooling is replaced per the quality plan and the equipment is functioning properly.Pm records were inspected and found to up to date during production of the involved sub-lots.A device history record review showed no non-conformances associated with this issue during the production of this batch.H3 other text : see h10.
