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.Conclusion: the device was returned for evaluation.A visual inspection of the device found a kink and partial break in the outer catheter shaft.Therefore, the investigation is confirmed for both a kink and break in the shaft.No signs of rupture were identified in the outer balloon material.A leak in the inner guidewire lumen was identified during an attempt to inflate the balloon.However, the source of the leak could not be identified.Therefore, the investigation is confirmed for a leak.However, the investigation is inconclusive for the reported rupture, as the balloon was unable to be fully inflated to inspect for ruptures, due to the leak in the guidewire lumen.Although the specific location of the leak from the inner guidewire lumen could not be determined, the source of the leak was isolated to the lumen under the proximal portion of the balloon.It is possible that the leak originated at the kink under the proximal cone of the balloon.However, the definitive root cause for the leak, or other reported and identified issues, could not be determined based upon available information.Labeling review: the current (b)(4) ifu (instructions for use) states: warnings: to prevent vessel damage, the inflated diameter and length of the balloon should approximate the diameter and length of the vessel just proximal and distal to the stenosis.Select a balloon size so that its inflated balloon diameter does not exceed the minimum vessel diameter when diameters of a target vessel vary.[or, it can cause vessel injury.] when the catheter is exposed to the vascular system, it should be manipulated while under high-quality fluoroscopic observation.Do not advance or retract the catheter unless the balloon is fully deflated.If resistance is met during manipulation, determine the cause of the resistance before proceeding.[applying excessive force to the catheter can cause vessel damage and the catheter can result in tip or catheter breakage, catheter kink or balloon separation.] do not exceed the rbp recommended for this device.To prevent over pressurization, use of inflation device with manometer is recommended.[balloon rupture may occur if the rbp rating is exceeded.] careful attention must be paid to the dilatation of calcified lesions or tortuous anatomy.[it may lead to catheter damage or balloon rupture.} prohibitions: do not reuse.Do not resterilize.(b)(4).
