A review of the dimensional verification, complaint history, device history record, instructions for use (ifu), quality control and a visual inspection of the returned device was conducted for the purpose of this investigation.One advance 35 lp low profile balloon catheter was returned for investigation.A leak test was performed and a pinhole leak was observed in the balloon.The leak was noted 1 cm from the distal end.A complaint history search noted this is the only complaint related under its lot.There is no evidence to suggest the product was not manufactured to current specifications.The ifu included with the device instructs the following: "do not exceed rated burst pressure.Rupture of balloon may occur.Over-inflation may cause rupture of the balloon, with result damage to the vessel wall.The burst pressure data was analyzed using factors for a one-sided tolerance to determine with 95%confidence that 99.9% of these balloons would not burst at or below the calculated rated burst pressure.In heavily scarred access sites, use of an introducer sheath is recommended.Use only the recommended balloon inflation medium.Choose a balloon appropriate to lesion length and vessel diameter.Upon removal from package, inspect the catheter to ensure no damage has occurred." it is likely that the patient's anatomy may have contributed to the device failure; however based on the available information a definitive root cause could not be determined.We will continue to monitor for similar events.
