(b)(4).The reported lot number (16f21m0029) matches the lot number on the returned original packaging pouch/label.Returned for investigation was a 5fr.80cm berman catheter with the original packaging pouch.Upon return, the catheter body was immediately noted ruptured near the junction hub; the body was noted ruptured from approximately 88.9cm to 89.5cm from the distal tip of the catheter.The supplied control stroke syringe was noted connected to the inflation lumen stopcock; no damage or abnormalities were noted to the returned syringe.The inflation lumen stopcock was in the closed position.The recommended volume capacity of the balloon is 0.75cc.Upon microscopic inspection, a wrinkle was noted on the balloon; no damage was noted to the balloon.No condensation was noted within the inflation lumen extension line.No contrast media was noted within the injection lumen extension line.Dried blood/contrast media was noted within the berman holes (injection lumen) near the catheter tip.Dried blood was noted on the exterior of the sample.No other damage or abnormalities were noted.The inflation lumen was injected with 0.75cc of air using the returned control stroke syringe.The balloon inflated symmetrically.One side of the balloon measured approximately 4mm.The other side measured approximately 4mm.The inflation lumen was injected with 0.75cc of air using the returned control stroke syringe.The balloon inflated symmetrically.The balloon deflated in less than 3 seconds when the syringe was removed.No pull away was noted after the tug test.The balloon was placed in water and air was injected into the inflation lumen again.No leak was noted.The damaged/ruptured catheter body did not result in damage to the inflation lumen.The catheter's injection lumen was aspirated/flushed, and air was noted leaking from the damaged/ruptured catheter body.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 of catheter body cut/torn during use is confirmed.The catheter body was found ruptured near the junction hub upon receipt of the sample.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 ruptured catheter body.The root cause of the ruptured catheter body is undetermined.Other remarks: n/a.Corrected data: n/a.
