Product condition received: the product was returned with the membrane completely unfolded and blood on the exterior of the catheter.The returned sheath was over the catheter and partially covering the rear portion of the balloon.Five kinks were found on the catheter located approximately 41.4cm, 70.9c, 71.9cm, 75.4cm and 75.9cm from the iab tip.No blood was found inside the catheter.Product evaluation: an underwater leak test of the balloon, catheter, y-fitting and extracorporeal tubing was performed and no leaks were detected.The iab ws placed on the cs300 pump and pumped for two hours which represents one complete autofill cycle.The iab pumped normally and no alarm sounded from the pump.Conclusion: the reported problem could not be duplicated during testing.We are unable to determine when the kinds occurred, however if the kinks occurred during the procedure it could restrict the gas flow through the iab which could cause the reported alarm.A review of the device history does not indicate any lot specific issues.(b)(4).
