The product was returned with the membrane completely unfolded with traces of blood on the exterior of the catheter.The pressure tubing was also returned.A catheter tubing/inner lumen kink was observed at approximately 66cm from the iab tip.Additionally, an optical fiber break was also observed at the catheter tubing/inner lumen kink site.An underwater leak test of the balloon, catheter tubing, y-fitting, extracorporeal tubing and pressure tubing was performed and no leaks were detected.The technician attempted to insert a 0.025¿ laboratory guidewire through the inner lumen and found to have traces of dry blood.Additionally, a guidewire insertion obstruction was felt at the inner lumen kink site.The iab was placed on the cs300 pump and did not inflate.The condition of the iab as received indicated a significant kink which restricted gas passage, resulting in poor inflation on the pump.However, we are unable to determine when this kink 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 ((b)(4)) - 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 ((b)(4)) - the review of the historical data was performed.Trend analysis ((b)(4)) - the overall complaint trend data for the period oct-19 through sep-21 was reviewed.Communication/interviews: ((b)(4)) communication/interviews were performed to obtain all possible information.Reference complaint #(b)(4).
