A further clinical review was performed and identified this event to be mdr reportable pursuant to 21 cfr part 803.The device history records have been reviewed with special attention to the raw materials, the subassemblies, the manufacturing process and the quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.The device was returned.The complaint investigation is confirmed for a longitudinal rupture on the barrel of the balloon.Per the ifu, during catheter preparation, air is supposed to be removed from the catheter using standard catheter de-airing techniques.The ifu does not state to inflate the balloon during preparation, as the balloon is only meant to be inflated during use within the patient.Additionally, the complaint comments mention that the user was measuring the balloon with calipers during inflation, which could have contributed to the rupture.The condition of the returned balloon demonstrated a high pressure rupture, indicating that the balloon was over pressurized past its rbp of 6atm.The true dilatation balloon instruction for use (ifu) provides general instructions for use of the device, as well as warnings, precautions, and potential complications associated with the device.Do not exceed maximum inflation pressure indicated on label.Excess inflation pressure can cause balloon rupture and the inability to withdraw catheter through introducer sheath.The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bard.
