As reported, the 2mm 20cm saber percutaneous transluminal angioplasty (pta) balloon broke during balloon dilatation angioplasty of lower extremity arteries.There was a hole on the balloon; therefore, it cannot be inflated.The procedure was completed by changing to a new balloon.There was no reported injury to the patient.The product was stored properly according to the instructions for use (ifu).There was no difficulty removing the product from the hoop.There was no difficulty removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.No kinks or other damages were noted prior to inserting the product into the patient.The device prepped normally, maintaining negative pressure.The intended procedure was for the peroneal artery.The lesion was stenotic and mildly calcified.There was no tortuosity and there was 70% stenosis.The device was not used for a chronic total occlusion (cto).The contrast to saline ratio was 1:1.The same indeflator was used successfully with other devices.There was no resistance or friction while inserting the balloon through the rotating hemostatic valve.There was no resistance or friction while inserting the balloon through the guide catheter.There was no difficulty advancing the balloon catheter through the vessel.There was no difficulty crossing the lesion.The catheter was never in an acute bend.The balloon catheter did not kink while being used.Two images provided for review.The angiographic image is of poor quality and failure cannot be determined based on the image provided.The second image contains the saber device; however, the failure cannot be identified.The device was then returned for evaluation.A non-sterile ¿saber 2mm20cm 150¿ was received for analysis coiled inside of a clear plastic bag.The device was unpacked to proceed with the product evaluation.A thorough inspection was performed observing no damage or anomalies.The balloon was returned deflated.No other outstanding details were observed.Functional testing was performed.One inflator/deflator device was attached to the inflation port.Positive pressure was applied with the purpose of reach the rated burst pressure.However, inflation pressure is not maintained due to the burst condition observed on the balloon.The balloon was inspected with a vision system observing a rupture on the surface where the water is leaking.The balloon surface presented evidence of a ruptured condition and secondary scratch marks located near the damaged border area.This type of damage is commonly caused during the interaction of the material with a sharp object or mechanical damage.It is very likely that the same factors that caused the observed scratch marks on the surface could probably led to the damaged condition found on the received device.It seems that the material near the damaged area was affected by a sharp object from the outside of the device.The reported ¿balloon leakage during positive pressure¿ was observed during analysis of the returned device.However, the exact cause could not be determined.A leakage was observed during functional testing revealing a rupture and scratch marks on the balloon material.The balloon material likely encountered calcified spicules during delivery or upon balloon expansion.Therefore, based on the analysis provided, vessel characteristics of mild calcification and 70% stenosis contributed to the reported event as calcification is known to damage balloon material.According to the warnings in the safety information in 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.¿ the information available, nor product analysis suggests a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
