'date received by mfg' on initial emdr should have been 01/20/2020, not 01/20/2019.The iab was returned with the membrane loosely folded with traces of blood on the exterior of the catheter.The one-way valve and maquet sheath.The one-way valve was also returned and attached, along with a 6¿ maquet sheath.The sheath was found to be ribbed at 14.7 cm from the sheath hub.Additionally, the catheter tubing was noticed to be flattened along its length.This deformation may occur if a vacuum is held with the one-way valve for an extended period of time, causing the catheter tubing to lose its round shape.An underwater leak test of the balloon, catheter, y-fitting and extracorporeal tubing was performed and no leaks were detected.The technician successfully inserted the laboratory 0.018" guidewire through the inner lumen and no signs of blood were observed on the guidewire.The inner lumen leak test was performed and passed with no leaks.Due to the returned condition of the iab, the complaint could not be confirmed to mimic the reported event.A device and lot history record review was completed for the reported product.No nonconformances were found that are considered to be related to the event.Complaint record # (b)(4).
