One 120804f fogarty catheter was returned for examination.The reported event of balloon issue was confirmed.The catheter body was broken at the proximal end of the proximal balloon windings.The edges at the break locations appeared to match.Part of the proximal balloon windings had unraveled but remained attached.Per the ifu "balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures." and "to minimize the risk of vessel damage, balloon rupture, or tip detachment, do not exceed the maximum recommended inflation and pull force for each size catheter." both the balloon latex and distal balloon windings were intact.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint.Per the instructions for use, balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures.To minimize the risk of vessel damage, balloon rupture, or tip detachment, the maximum recommended inflation volume and pull force for the catheter should not be exceeded.The arterial embolectomy catheter is not recommended for the removal of fibrous, adherent, or calcified material (e.G.Chronic clot, atherosclerotic plaque).This catheter is not designed to withstand the additional pull force needed to remove these materials.To minimize the risk of vessel or membrane damage, the maximum recommended pull force for the catheter should not be exceeded.As with all catheterization procedures, complications may occur.These may include local or systemic infection, local hematomas, intimal disruption, arterial dissection, perforation and vessel rupture, hemorrhage, arterial thrombolysis, distal emboli or blood clots or arteriosclerotic plaque, air emboli, aneurysms, arterial spasms, arteriovenous fistula formation, membrane separation and distal embolization.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.
