An advance 14 lp low profile balloon catheter was used in an unspecified procedure.Treatment of the right popliteal artery was conducted by right groin approach.Slight calcification was observed in the target lesion.The catheter was advanced to the lesion through another manufacturer's 5 fr.Sheath and wire guide.After the complaint device passed through the lesion, dilation was began.The physician attempted to inflate the balloon up to 16atm (rbp).However, before the air pressure reached 16atm, the balloon got ruptured longitudinally.The exact pressure when it ruptured was unknown, but presumably 12atm or 13atm.It was replaced with another pta balloon in another size (4mm*2cm, lot#: unknown) and the procedure was completed successfully.No adverse effects to the patient were reported due to this occurrence.

Additional information: device available for evaluation.Investigation - evaluation: a review of complaint history, device history record, documentation, drawing, ifu, specifications, quality control data, and visual inspection of the returned product was conducted during the investigation.One used advance 14 lp low profile balloon catheter (ptax4-14-170-4-4) was returned for evaluation.No non-conformities were noted regarding the surface of catheter.Catheter was smooth, clean and not damaged.The balloon is ruptured longitudinally.The length of the balloon was within specifications at 39mm.Review of the device history record for this lot shows 11 nonconforming events that would contribute to this failure mode.There was one other reported complaint for this lot number.There is no information regarding the patient anatomy including any tortuous or calcified vessels.There is no information regarding the competitor devices used with during this procedure and if these devices met their manufacturer's quality specifications.There is no information regarding preparation of the device.There is no information regarding handling of the device during the procedure.It is stated that "a slight calcification was observed within the target lesion".Calcifications can have unexpected sharp protrusions which can damage the balloon and contribute to rupture and/or tear.Although a definitive root cause cannot be determined, it is possible that the calcification noted in the lesion could have contributed to the rupture of the balloon.Based on the provided information, inspection of returned product, and results of the investigation; a definitive root cause cannot be established or reported at this time.Per the quality engineering risk assessment, no further action is warranted.Monitoring will continue to be performed for similar complaints.
