Product condition received: the product was returned with the membrane completely unfolded and blood found on the exterior of the catheter.The returned sheath was over the catheter and partially covering the rear portion of the balloon.Three kinks were found, on one the inner lumen approximately 21.6cm from the iab tip and the other on the catheter tubing 42.4cm and 75.9cm from the iab tip.Product evaluation: an underwater leak test of the balloon, catheter, y-fitting and extracorporeal tubing was performed and no leaks were detected.The iab was placed on the cs300 pump and pumped for two hours which represents one complete autofill cycle.The iab pump normally and no alarm sounded from the pump.Conclusion: the reported problem could not be duplicated during testing.We are unable to determined when the kinks occurred, however if the kinks occurred during the procedure it could restrict the gas flow through the iab which could cause the report alarm.A review of the device history does not indicate any lot specific issues.(b)(4).
