(b)(4).The reported complaint for iab kinked was confirmed upon the investigation of the returned sample.The customer returned a 30cc 7.5fr ultraflex intra-aortic balloon catheter (iabc) with the original packaging that matches the serial number of the returned iabc (inp-2, inp-3) for investigation.The sample was returned in a cardboard box and was loosely packed within the original packaging carton/tray (inp-1, inp-2).Returned with the sample was the supplied 30cc driveline tubing (inp-4).Upon return, the peel away sheath was noted on the returned iabc (inp-4, inp-9).The one-way valve was tethered to the short driveline tubing (inp-4, inp-6).The bladder was fully unwrapped (inp-7).The iabc central lumen was noted broken within the flex-tip assembly area at approximately 5.8cm from the iabc distal tip (inp-8).Dried blood was noted on the exterior surfaces of the returned sample.No obvious blood was noted within the bladder/helium pathway.The one-way valve was tested and passed.A vacuum was pulled on the one-way valve, and it held for at least 1 minute and then 30 seconds five separate times according to quality system document.An attempt to aspirate and flush the catheter using a 60cc lab-inventory syringe was unable to be successfully completed due to a blocked/clotted central lumen.Immediate push back on the syringe plunger was experienced.The blockage, most likely dried blood, was unable to be cleared.The iabc was leak tested in accordance with testing methods from manufacturing procedure.A leak was immediately detected from the iabc distal tip ( anp-1).The leak from the iabc distal tip is consistent with the damaged central lumen (inp-8, anp-2, anp-3).The iabc was leak tested again with the iabc distal tip blocked off; no other leaks were detected.A lab inventory 0.025in guidewire was back loaded through the iabc distal tip.The guidewire exited the central lumen and entered the bladder at the location of the flex-tip assembly break.Some blood was noted on the guidewire.The guidewire was front loaded through the iabc luer.The guidewire met resistance and could not advance at approximately 1.2cm from the iabc luer due to a blocked central lumen.Some blood was noted on the guidewire.Based on a review of the device history record (dhr), the product met specification upon release; however, the specifications were not met during the complaint investigation due to the damaged central lumen.The root cause of the complaint was undetermined.Further investigation has been initiated under teleflex's quality system by the manufacturing site to further investigate this issue.Teleflex will continue to monitor and trend on reports of this nature.
