(b)(4).The tx30v package was visually inspected and it was found that the ripped and torn tyvek occurred while opening the product and that the sterile barrier was fully in place before the package was opened.Tyvek delamination was confirmed.Tyvek ripped and stuck to the blister flange when package was opened due to tyvek delamination (separation of tyvek layers.) tyvek delamination causes the package to be difficult to open and difficult to remove the device from the package using sterile technique.The package blister was fine with no defects and there was evidence of seal transfer from the tyvek to the blister flange on the entire circumference of the blister.Possible causes of tyvek delamination are tyvek quality, seal strength, or opening technique.Lot history records for m4h02u, product code tx30v, were reviewed.No protocols, defects, non-conformances or quarantine noted.The product met all in-process and finished goods specifications upon release of the product.Lot history records for m4h02u, product code tx30v, were reviewed.No protocols, defects, non-conformances or quarantine noted.The product met all in-process and finished goods specifications upon release of the product.
