One 12a0602f catheter was returned for examination.The reported event of "a metal piece from the catheter body sticking out of catheter" was confirmed.As received the balloon latex and distal balloon windings were not returned.A cutdown of the proximal winding found no latex under the winding.The spring tip in the catheter body was fully stretched.Adhesive was not visible at the end of the spring.The proximal balloon windings appeared to be in good condition without any damage or abnormality.No other visible damage was observed from the catheter.A review of the manufacturing records indicated that the product met specifications upon release.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint.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.Exposure to the atmosphere, handling during insertion, and plaque and other deposits within the blood vessel may cause latex membrane degradation.In this case the latex membrane was torn in a way that allowed the spiral cable to be exposed.There is a possibility of vessel damage if the spiral cable is outside of the latex membrane and possibly in contact with the vessel.It should be note that the ifu indicates that "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.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.
