The product was returned with the membrane completely unfolded with traces of blood on the exterior of the catheter.The extender tubing was also returned.Two inner lumen kinks were observed inside the membrane at approximately 20.3cm & 24.1cm from the iab tip.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal tubing and extender tubing was performed and no leaks were detected.A laboratory insertion test was unable to be performed due to the returned condition of the iab.Although we were unable to mimic the clinical settings and were unable to perform a laboratory insertion test due to the returned condition of the iab, kinks to the inner lumen may contribute to a difficult insertion through the sheath.However, we are unable to determine when these kinks may have occurred.The evaluation confirmed the reported problem.A non-conforming material report review was completed for the reported product.No nonconformances were found that are considered to be related to the event.Analysis of production (3331/213) - the device history records review concluded that there were no ncmrs, rework, or deviations documented for the reported lot/serial number.Based on the review results, it was determined that there is no relation between the manufacturing process and the reported failure.Historical data analysis (4109/213) - the review of the historical data was performed.Trend analysis (4110/213) - the overall complaint trend data for the period oct-19 through sep-21 was reviewed.Communication/interviews: (4111/213) communication/interviews were performed to obtain all possible information.Reference complaint #(b)(4).
