Contact person occupation: clinical educator.The product was returned with the membrane completely unfolded with blood on the exterior of the catheter, within the statgard and between the catheter and the returned maquet sheath.The pressure tubing was also returned.A catheter tubing/inner lumen kink was observed at approximately 46.2cm from the iab tip.Additionally, a catheter tubing/inner lumen/optical fiber break was also observed near the y-fitting at approximately 75.9cm from the iab tip.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal tubing and pressure tubing was performed and a leak was detected at the catheter tubing/inner lumen/optical fiber break site.The break found in the inner lumen appears to have been the result of a severe kink, which eventually failed and allowed blood to leak into the membrane, statgard and catheter tubing.However, we were unable to determine when this may have occurred.Additionally, kinks to the catheter tubing may contribute to an autofill failure.The evaluation confirmed the problem.A device and lot history record review was completed for the reported product.No nonconformances were found that are considered to be related to the event.The failure mode is addressed in the risk file and is operating within its risk profile.The ifu addresses the reported failure.There were no ncmrs identified which could cause or contribute to the reported failure.The investigation does not indicate that the device was inadvertently released as non-conforming or an adulterated product or was a counterfeit.The complaint history review did not identify an adverse trend (increase in number of complaints over past three (3) months).Based on the rational provided above, no escalation to the capa process is required.Reference complaint #(b)(4).
