It was reported, a (b)(6) year old male patient with a history of coronary artery disease, diabetes (type unspecified) and hypertension, underwent an unknown procedure in which the advance 35 lp low profile balloon catheter was used.It was noted that the patient had plaque and calcium build up in the superficial femoral artery (sfa).The lesion was located in the distal sfa.,which was seventy per cent occluded.There were no issues gaining access in the groin.At approximately mid to distal sfa, the initial inflation of the balloon inside a stent was taken up to 15 atmospheres (atm).The balloon started to leak and blood backed up into the inflation device due to a hole in the balloon.The physician removed the device intact without a sheath and used another balloon to complete the procedure.Nothing detached in the patient.No tortuosity or angulation was present in the patient's vessel.Optiray contrast in a 50/50 ratio to saline was used to inflate the balloon.No additional procedures were required.The patient did not experience any adverse effect.

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 pta5-35-135-6-20.0 device was returned for investigation with biomatter present inside and on the balloon.The balloon was inflated with water and a pinhole leak was noted approximately 12.5cm from the proximal balloon bond.The balloon was then inflated with air inside of a water filled beaker in order to photograph the pinhole leak.This ability to recreate the failure mode confirmed the customer¿s complaint.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 manufacturer¿s instructions, drawings, and quality control procedures were conducted, and no gaps were discovered.Through these reviews, cook has confirmed that appropriate measures are in place to address this failure mode prior to distribution.Moreover, an ifu is provided with this device, which states the intended use of this 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." the ifu 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 to the patient¿s condition.Reportedly, the patient¿s vessel was 70 percent occluded.We will continue our monitoring of similar complaints and have notified the appropriate personnel of this event.Measures are being conducted to address this failure mode.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.
