Blank fields on this form indicate the information is unknown, unavailable, or unchanged.Event summary: as reported, during a thoracic endovascular aneurysm repair procedure, an advance 35 lp low profile balloon catheter ruptured.The balloon catheter was used for pre-dilation, prior to placing a stent graft.The device was inflated once to 8 atmospheres, using an unknown inflation device and solution, when the rupture occurred.The balloon was not inflated within a stent.The device was removed by itself, and another device of the same type was used to complete the procedure.No adverse effects to the patient were reported.Additional information: h6 (annex g).Investigation - evaluation.Reviews of the complaint history, device history record, drawing, specifications, instructions for use, and quality control procedures of the device were conducted during the investigation.No device was returned for investigation.A document-based investigation evaluation was performed.No related non-conformances were recorded, and there have been no other reported complaints for this lot number.The device history record review provides objective evidence that the device was manufactured to specification.There is no evidence of nonconforming devices from the complaint lot in house or in the field.The device is provided with instructions for use which warn, ¿do not exceed rated burst pressure.Rupture of balloon may occur.Adhere to balloon inflation pressure parameters in the compliance card insert.Over-inflation may cause rupture of the balloon, which resultant damage to the vessel wall.Use of a pressure gauge is recommended to monitor inflation pressures.¿ the ifu further states, ¿note: if resistance is met while advancing the balloon dilatation catheter, determine the cause and proceed with caution.¿ based on the available information, cook has concluded that a manufacturing and quality control deficiency contributed to this failure mode.A previous capa investigation determined that inadequate preventive maintenance of folding equipment, inadequate process controls for folding and bonding processes, and inadequate qc work instructions for inspection microtears were the root causes of this failure mode.Corrective actions were implemented to address these root causes after the reported lot for this complaint was manufactured.Cook will continue monitoring of similar complaints and has notified the appropriate personnel of this event.Per the quality engineering risk assessment, no further action is required.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
