Manufacturing review: the device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only complaint reported to date for this lot number and failure mode.Visual/microscopic inspection: the balloon size for this product is printed on the balloon hub of the catheter and identified the returned sample as a 2.5mm x 220mm x 150cm balloon.The device was examined under microscopic magnification and a complete circumferential break was noted on the inner lumen 33.2cm from the distal tip, and a completed circumferential break of the outer catheter was noted at the glue joint.The inner lumen measured 119.8cm from the strain relief to the circumferential break in the lumen; stretching was noted to the inner lumen at the point of the break.The balloon segment of the device included the distal tip, the balloon and a portion of the inner lumen.No other anomalies were noted to the bifurcate or proximal portion of the catheter.Functional/performance evaluation: functional testing was not conducted to the returned sample condition.Medical records review: medical records were not provided; therefore, a review could not be performed.Image/photo review: images/photos were not provided; therefore, a review could not be performed.Conclusion: the device was returned in two complete segments.The device was examined under microscopic magnification and breaks were noted to the inner lumen and outer catheter, with the entire balloon detached from the proximal end of the device.Therefore, the investigation is confirmed for a break and for balloon detachment.Additionally, the investigation is inconclusive for the device not looking right when removed from the packaging, as the device was returned already opened from the packaging, and as the original condition of the device could not be verified.Stretching was noted at the inner lumen break, likely indicating that force was applied to the returned device.It is likely that the force applied to the device resulted in the breaks in the device and the detached balloon.However, the definitive root cause for the reported issue could not be determined based upon the available information.It is unknown if procedural issues during removal of the device from the packaging contributed to the reported event.Labeling review: the current ifu (instructions for use) states: dilatation catheter preparation: remove the balloon guard and stylet by grasping the balloon catheter just proximal to the balloon and with the other hand, gently grasp the balloon protector and slide distally off of the balloon catheter.Precautions: if resistance is felt during post procedure withdrawal of the catheter, it is recommended to remove the balloon catheter and guidewire/introducer sheath as a single unit.Potential adverse reactions: additional intervention equipment required.Luer lock syringe/inflation device with manometer (10 ml or larger).
