It was reported, an (b)(6) male was undergoing a procedure to treat the pelvic stenosis in the calcified common iliac artery (a.Iliaca communis) and the "afs" stenosis farther down in the leg.The complainant reported there was "not too much angulation or tortuosity of the vessel." during it's first inflation, the advance 35 lp low profile balloon catheter ruptured longitudinally.An inflation device was used to inflate the complaint balloon to eight atmospheres (atm) for ten seconds when it ruptured.Another manufacturer's six french, ten cm sheath was used.It is not known what type or ratio of contrast was used.No blood was noted in the inflation device and the complaint balloon was not inflated inside a stent prior to rupture.The procedure began with access in the left groin in a contralateral fashion to treat the forty percent occluded lesion in the right superficial femoral artery.During advancement over the common femoral artery on the left side there was a calcified stenosis.It was during the first inflation in this area that the rupture occurred.The physician was able to remove the complaint balloon though the sheath, rather than as a unit with the sheath, without difficulty.Another advance 35 lp low profile balloon catheter was used to successfully complete the procedure.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.

Investigation/evaluation: reviews of the complaint history, device history record, drawing, instructions for use (ifu), manufacturer¿s instructions, quality control, specifications, and a functional test & visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned package confirmed that one pta5-35-80-8-4.0 was returned for investigation.Slight biomatter was present throughout the device.The balloon was split longitudinally down the entire length of the balloon, from proximal bond to distal bond.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.A review of the device history record showed no nonconforming events which could contribute to this failure mode.It should also be noted there were no other reported complaints for this lot number.Furthermore, reviews of the manufactures instructions, quality control procedures, and overall design history file were conducted, and no gaps were discovered.Moreover, an ifu is provided with the device, which states that the device is ¿for percutaneous transluminal angioplasty (pta) of lesions in peripheral arteries including iliac, renal, popliteal, infrapopliteal, femoral, and iliofemoral as well as obstructive lesions of native or synthetic arteriovenous dialysis fistulae." it goes on to say, ¿if balloon pressure is lost and/or balloon rupture occurs, deflate balloon and remove balloon and sheath as a unit." based on the information provided and the examination of the returned product, investigation has concluded that this event cannot be traced to the device, but likely lies with the patient¿s anatomy as severe calcification was noted in the target lesion.We will continue our monitoring of similar complaints and have notified the appropriate personnel of this event.Per the quality engineering risk assessment no further action is required.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
