As reported, during a dilation procedure for stenosis involving a male patient of unknown age, an advance 35 lp low profile balloon catheter would not deflate.The balloon was used inside of an unknown manufacturer's stent to "be sure that the stent was well against the wall of the artery".When the physician tried to remove the balloon, it would not deflate.It was then reported that the balloon ruptured and the user was able to remove the device using the introducer.The procedure was reportedly prolonged, exposing the patient to x-ray, and the patient bled "more than necessary"; however no interventions related to bleeding have been reported.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.Additional information regarding event details and outcome has been requested, but is not available at this time.

Investigation ¿ evaluation: reviews of the dimensional verification, complaint history, device history record, instructions for use (ifu), manufacturer¿s instructions, quality control, and a functional test & visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned package confirmed that the correct device was returned for investigation.A wire guide was found extending out either end of the complaint device along with what appeared to be a 6 fr.Sheath.The balloon material was found to have a circumferential tear, with the distal piece of the balloon material umbrellaed over the distal tip of the catheter.Between the balloon bonds, where the balloon material would normally be, the catheter shaft was found to be elongated.This was expected based on the appearance of the distal portion of the balloon material.The catheter shaft was outside of the accepted tolerance when tested.It also attributed to the elongation found, therefore could not be confirmed as out of specification.The functional test was limited due to the balloon material having been torn.However, the balloon lumen was itself was flushed successfully.No major account of biological matter was noted on the device.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 one nonconforming event which could potentially contribute to this failure mode.This nonconformance was for a failed leak test.This nonconformance was scrapped and not replaced prior to order completion.It should also be noted there were no other reported complaints for this lot number.Furthermore, reviews of the manufacturer¿s instructions and quality control procedures were conducted, and no gaps were discovered.Moreover, an ifu is provided with this device, which note that the device is indicated for percutaneous transluminal angioplasty (pta) of lesions in peripheral arteries; including iliac, renal, popliteal, infrapopliteal, femoral and iliofemoral; and obstructive lesions of native or synthetic arteriovenous dialysis fistulae.There is no indication for post-dilatation of a stent, for which the complaint device was intentionally used.Based on the information provided and the examination of the returned product, investigation has concluded that a root cause for this event could not be established.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.
