As reported, blood was noted in the indeflator after inflation of the balloon of a saber.035 6mm x 12cm 135 cm percutaneous transluminal angioplasty (pta) in the right iliac artery at 4 atmospheres (atm).The physician removed the balloon from the patient in one piece.The procedure was completed with the use of non-cordis balloons and another.035 saber without issue.There was no reported patient injury.The procedure being performed was reported to be a right leg angiogram and a retrograde approach was used, using a non-cordis sheath.Vessel calcification was moderate to severe in places; vessel tortuosity was also severe with one-hundred percent stenosis.The device was not used for a chronic total occlusion (cto).The device was stored, handled , and prepped according to the instructions for use (ifu).There were no visible signs of device/package damage prior to use.There was no difficulty removing the product from the hoop or removing the protective balloon cover nor difficulty removing the stylet or any of the sterile packaging components.There were no kinks or other damages noted prior to inserting the product into the patient.The device maintained negative pressure during preparation.An indeflator was used and the same indeflator was successfully used with other devices.The contrast to saline ratio was 50/50.There were no anomalies noted while inflating the device with positive pressure.There was no anomaly to the device which prevented it from inflating.There was a loss of pressure noted; blood was seen in the indeflator and the balloon burst.The balloon was not examined to determine a balloon tear or pinhole.The gauge of the indeflator did not indicate a loss of pressure when the anomaly was noted.The device is expected to be returned for evaluation.

blood was seen in the indeflator and the balloon burst.The balloon was not examined to determine a balloon tear or pinhole.The gauge of the indeflator did not indicate a loss of pressure when the anomaly was noted.The device was returned for analysis.A non-sterile saber.035 6 x 120 135cm sl was received coiled inside of a clear plastic bag.The device was unpacked to proceed with the product evaluation.The unit was thoroughly inspected observing that no damages or anomalies were noted during the unaided eye visual inspection.The balloon was received deflated.Functional testing was performed using an inflator/deflator device attached to the inflation port, positive pressure was applied with the purpose of reaching the rated burst pressure.During testing the balloon could not be inflated, and a leak was noted as water was observed flowing out of the balloon through a located puncture.Sem analysis confirmed the presence of scratch marks near the leakage condition identified in the microscopic analysis as a puncture damage.A product history record (phr) review of lot 82241207 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon leakage during positive pressure¿ was confirmed via device analysis as a leakage of water was noted during functional analysis.However, the exact cause cannot be determined.Sem analysis was performed, results showed that the leakage on the balloon was caused by a puncture on the external balloon material which presented evidence of scratch marks near the damage.Scratch marks are commonly caused during the interaction of the material with a sharp object or mechanical damage.Additionally, the balloon material near the rupture appears to have been punctured either due to the interaction of the balloon with calcified spicules located on the lesion or with a sharp object from the outside of the balloon.Therefore, based on the information available for review, it is likely vessel characteristics and procedural factors contributed to the event reported as evidenced by device analysis.According to the safety information of the instructions for use ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.To reduce the potential for vessel damage or the risk of dislodgement of particles it is very important that the inflated diameter of the balloon should approximate the diameter of the vessel just proximal and distal to the lesion.The balloon dimensions are printed on the product label.The compliance table incorporated with the product shows how balloon diameter increases as pressure increases.Do not exceed the rated burst pressure recommended on the label.The rated burst pressure is based on the results of in vitro testing.At least 99.9% of the balloons (with a 95% confidence) will not burst at or below their rated burst pressure.Use of a pressure monitoring device is recommended to prevent over-pressurization.Pressure in excess of the rated burst pressure can cause balloon rupture and potential inability to withdraw the catheter through the introducer sheath.Balloon rupture can cause vessel damage and the need for additional intervention.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).Never use air or any gaseous medium to inflate the balloon.If resistance is met during manipulation, determine the cause of the resistance before proceeding.If resistance is felt upon removal, then the balloon, guidewire and the sheath should be removed together as a unit, particularly if balloon rupture or leakage is known or suspected.Proper functioning of the catheter depends on its integrity.Care should be used when handling the catheter.Damage may result from kinking, stretching, or forceful wiping of the catheter.Forceful handling can result in catheter separation and the subsequent need to use a snare or other medical interventional techniques to retrieve the pieces.Always verify integrity of the catheter after removal.¿ neither the phr nor the information available suggests a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
