Batch review performed on 13 may 2019 lot 160424: (b)(4) items manufactured and released on 10-mar-2016.Expiration date: 2021-03-08.No anomalies found related to the problem.To date, (b)(4) items of the same lot have been already sold without any similar reported event.Manufacturing process review: event notified to coating manufacturer on the 26 april 2019.On the (b)(6) 2019 the coating supplier reported as follow about this complaint: this episode is similar to other reported in 2018 and, in every cases, pieces were made in 2016 or before.After previous complaints, a final check was added on pieces produced in vps in order to check if there is material loss from the device.In this case, the particles present in the package, can be due to the fact that device is smaller than blister dimension and the shell is free to move inside it with the consequence of more debris loss.Visual inspection performed by (b)(4): we confirm the presence of coating debris in the packaging.Actually, we perform a double check on the packaging as per (b)(4) in order to find impurity inside the blister and on the packaging welding.In this case the packaging was conform (no impurity).For this reason the debris inside the packaging detached during transportation and so is not possible to identify the issue before the implant expedition from medacta.
