The product was returned with the membrane completely unfolded and blood on the exterior of the catheter and between the catheter and the sheath.The returned sheath was over the catheter and partially covering the rear portion of the balloon.The sheath was not a maquet product.The extender tubing was also returned.Five kinks were found on the catheter tubing approximately 42.9cm, 43.9cm, 44.2cm,45cm and 76.5cm from the iab tip.The inner lumen was found occluded with dried blood.The occlusion was unable to be cleared.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal and extender tubing was performed and no leaks were detected.The iab was placed on the cardiosave pump and the iab did not inflate.The condition of the iab as received indicated kinks in the catheter tubing.We are unable to determine when the kinks occurred, however the kinks found on the catheter tubing of the returned device restricted the gas passage and resulted in poor inflation and deflation on the pump.The evaluation confirmed the reported problem.A lot history record review was completed for the reported product.No nonconformances were found that are considered to be related to the event.Reference complaint #(b)(4).
