It was reported that "after insertion of a balloon catheter, a machine alarm was found, and after removal, blood leakage from the balloon was found, and the patient's counterpulsation was normal after replacement with a new catheter".The 2nd iab was inserted at the same insertion site.Additional information states that there was no patient harm or injury.The patient status is reported as "fine".

Qn#(b)(4).Returned for investigation was a 40cc 8.0fr rediguard intra-aortic balloon catheter (iabc) with the original packaging box that matches the serial number on the returned sample.Returned with the sample were supplied kit components including 40cc inflation driveline tubing, 9fr super arrow-flex (saf) sheath and data-scope inflation driveline tubing.The returned 9fr super arrow-flex (saf) sheath appeared used; dried blood was noted on the exterior surfaces of the saf sheath and clear fluid was noted within the sheath sidearm.Upon return, the one-way valve was tethered to the short driveline tubing.The bladder was fully unwrapped.Multiple bends to the iabc central lumen, consistent with flattened surfaces, were noted at approximately 55.5cm, 56.1cm and 57.8cm from the iabc distal tip.Dried blood was noted on the exterior surfaces of the returned sample.Dried blood was also noted within the iabc helium pathway.The bladder thickness was measured at six points with measurements ranging from 0.0070in-0.0077in and was within specification.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.The iabc central lumen was aspirated and flushed using a 60cc lab-inventory syringe.No abnormalities or debris were noted.The iabc was leak tested and a leak was immediately detected from the bladder membrane.Under microscopic inspection, a puncture on the iabc bladder, consistent with contact from a sharp object, was noted at approximately 24.2cm from the iabc distal tip.No other leaks were detected.A lab inventory 0.025in guidewire was back loaded through the iabc distal tip.Resistance was noted at approximately 55.5cm, 56.2cm and 58cm from the iabc distal tip, which are the locations of the previously noted flattened surfaces.The guidewire was able to advance through the central lumen.No blood or debris was noted.The guidewire was front loaded through the iabc luer.Resistance was noted at approximately 27.2cm, 28.6cm and 29.2cm from the iabc luer, which are the locations of the previously noted flattened surfaces.The guidewire was able to advance through the central lumen.No blood or debris was noted.A device history record (dhr) review was conducted for the lot number with no relevant findings.The device passed all manufacturing specifications prior to release.The reported complaint that "blood leakage from the balloon was found" is confirmed.During the investigation, a puncture to the bladder, consistent with contact from a sharp object, was found on the iabc bladder which caused the reported complaint and allowed blood to enter the helium pathway.No other leaks were detected during functional testing.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 bladder leak.The root cause of the bladder leak is undetermined.The most probable potential cause of how the catheter came into contact with a sharp object is customer handling.No further action required at this time.This will be monitored for any developing trends.Other remarks: n/a.Corrected data: n/a.
