As reported, the 2mm x 250mm 150cm saber percutaneous transluminal angioplasty (pta) dilatation catheter was used to pre-dilate and the balloon was not able to be inflated.There was a little resistance found when removing the device from the patient, but it was removed intact (in one piece) and replaced with another balloon and was used with no problem.There were no reports of patient injury.The device was used to treat a lower extremity occlusion.There were no damages found on the device or device packaging prior to opening.The device was stored and prepped in accordance with the instructions for use (ifu).There was no difficulty removing the protective balloon cover or any of the sterile packaging components.The target site was 90% stenosed.The access site was normal.The device did not maintain negative pressure during preparation.The device was not put into an acute bend at any point during the procedure.The device was able to cross the lesion and did not kink at any time during the procedure.There were no reports of patient injury.The balloon did not leak from any segment.The user was trained in the use of the device.The device will be returned for evaluation.

Complaint conclusion: as reported, the 2mm x 250mm 150cm saber percutaneous transluminal angioplasty (pta) dilatation catheter was used to pre dilate and the balloon was not able to be inflated.There was a little resistance found when removing the device from the patient, but it was removed intact (in one piece) and replaced with another balloon and was used with no problem.There were no reports of patient injury.The device was used to treat a lower extremity occlusion.There were no damages found on the device or device packaging prior to opening.The device was stored and prepped in accordance with the instructions for use (ifu).There was no difficulty removing the protective balloon cover or any of the sterile packaging components.The target site was 90% stenosed.The access site was normal.The device did not maintain negative pressure during preparation.The device was not put into an acute bend at any point during the procedure.The device was able to cross the lesion and did not kink at any time during the procedure.There were no reports of patient injury.The balloon did not leak from any segment.The user was trained in the use of the device.The device will be returned for evaluation.A non-sterile ¿saber 2mm25cm 150¿ was received for analysis coiled inside of a clear plastic bag.The device was unpacked to be evaluated.A thorough inspection was performed on the unit focusing on the luer hub as a cracked condition was observed.The balloon was received deflated with the manufacturing pleating.No other outstanding details were noticed.Functional testing was performed, an inflator/deflator device was attached to the inflation port.Positive pressure was applied with the purpose of reaching the rated burst pressure.However, a leaking condition was observed on the luer hub.The leaking impeded the balloon inflation due to the inability to maintain the pressure needed to inflate the balloon.All the pressure applied to inflate the balloon is lost through the leakage.Insertion/withdrawal testing was then performed, the balloon was inserted and withdrawn into the cannula of a lab sample 5 fr csi via the cap.No anomalies resistance or friction was felt during the insertion/withdrawal test.The luer hub was inspected with a vision system confirming the cracked condition.The cracked area on hub presented evidence of fatigue striation.Fatigue striations found on the hub material are commonly associated with damages caused by material tensile overload.Therefore, it is assumed that the hub material was induced to a tensile force that exceeded the hub material yielded strength prior to the cracked.The reported ¿pta/ptca system withdrawal difficulty¿ was not observed during insertion/withdrawal testing of the device.The balloon was inserted and withdrawn into the cannula of a lab sample 5 fr csi via the cap and no anomalies resistance or friction was noted.The reported ¿the reported ¿balloon inflation difficulty unable to inflate¿ was verified during analysis of the returned device due to a leakage observed coming from the luer hub which impeded a proper inflation.However, the exact cause cannot be conclusively determined.There were no anomalies noted to the balloon during functional testing; subsequently, a crack in the luer hub was observed.These findings likely contributed to the impression by the customer that there was a potential flaw on the balloon; however, this was not the case.Microscopic analysis revealed fatigue striations on the hub of the unit.The hub material was likely induced to tensile forces that exceeded the hub material yield strength.It is likely the handling of the product and procedural factors contributed to the event reported.Overtightening is the likely culprit and has been known to cause cracks in luer hubs.According to the information in the instructions for use ¿flush all devices entering the vascular system with sterile heparinized saline or similar isotonic solution.Prior to use, ensure all devices have been flushed and air is removed from the system according to standard medical practice.Failure to do so could result in air entering the vascular system.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).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.Proper functioning of the catheter depends on its integrity.Care should be used when handling the catheter.Preparation: attach a 3-way stopcock to the inflation port, which is marked ¿balloon¿.Attach a partially filled syringe with heparinized saline to the stopcock, open the stopcock to the balloon and induce negative pressure.Hold the syringe and proximal end of the catheter above the distal end of the catheter and hold the balloon vertically with the balloon tip pointing down.While maintaining negative pressure close the stopcock to the inflation port.Remove the syringe and purge the air.To ensure air contained in the balloon and inflation lumen is removed, apply negative pressure twice as instructed and repeat steps 2-4.Without twisting, slide the forming tube off the balloon.Prepare an angioplasty inflation system with a 50% solution of contrast medium in sterile saline or similar solution.Purge the air from the inflation device.Connect the inflation device to the 3-way stopcock that is connected to the catheter inflation port, open the stopcock to the catheter and slowly fill the inflation lumen and the balloon will slowly fill with diluted contrast medium.Caution: do not apply positive or negative pressure to the balloon at this time.¿ the information available, nor the product analysis suggest a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
