Our product evaluation laboratory received one model 120804f catheter.As received, a piece of the catheter body measuring approximately 5mm, was broken approximately 7mm from the catheter tip.The catheter body edges at the damaged site appeared to match up.The latex balloon was pierced by the broken catheter body part.The latex edges at the puncture site appeared to match up.Both windings were intact.The lab findings appeared consistent with the customer photo.No other visible damage was observed from the catheter.The customer report of "the balloon was punctured with the broken catheter tip" was confirmed on evaluation.An engineering evaluation has been initiated to assess for any manufacturing-related processes which could be correlated to the complaint.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.The instructions for use of the product contains the following statement: ¿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 thrombosis, distal embolization of blood clots and atherosclerotic plaque, air embolus, aneurysm, arterial spasm, arteriovenous fistula formation, and balloon rupture with fragmentation, tip 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.
