As reported, the 1.5 x 40 saber.014 percutaneous transluminal angioplasty (pta) balloon was opened and inserted into the patient.When the balloon went up in the artery, the product burst below rbp on present calcium.The device was removed intact from the patient.The procedure was completed with a different unknown balloon and the cto was eventually crossed and completed.The patient was unharmed.The device was stored properly according to the instructions for use (ifu).There was no difficulty removing the product from the hoop, removing the protective balloon cover, stylet, or any other sterile packaging components.There were no kinks or other damages noted prior to inserting the device into the patient.The device was prepped per the ifu and was able to maintain negative pressure.The intended lesion was noted to have a chronic total occlusion (cto).There was no resistance/friction while inserting the device through rotating hemostatic valve or while inserting through the unknown guide catheter.There was difficulty noted while advancing through the vessel due to the cto.The balloon catheter did not kink while being used.The device will not be returned for evaluation as it was discarded by the staff.The reported ¿balloon burst - at/below rbp¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Vessel characteristics of a chronic total occlusion likely contributed to the reported event.Damage to balloon material may have occurred upon crossing or during inflation.However, without the return of the device for analysis, it is difficult to draw a clinical conclusion between the device and the event reported.According to the instructions for use, which are not intended to mitigate risk, ¿carefully inspect the catheter prior to use to verify that the catheter has not been damaged and that its size, shape and condition are suitable for the procedure for which it is to be used.Flush or rinse all products entering the vascular system with sterile isotonic saline or a similar solution via the guide-wire access port prior to use.Never attempt to move the guide wire when the balloon is inflated.Do not advance the catheter against significant resistance.The cause of resistance should be determined via fluoroscopy.Inflation in excess of the rated burst pressure may cause the balloon to rupture.Use the recommended balloon inflation medium (25% contrast medium/75% sterile saline solution).It has been shown that a 25/75% contrast / saline ratio has yielded faster balloon inflation / deflation times.Never use air or other gaseous medium to inflate the balloon.If resistance is felt during post procedure withdrawal of the catheter through the introducer sheath, determine if contrast is trapped in the balloon with fluoroscopy.If contrast is present, push the balloon out of the sheath and then completely evacuate the contrast before proceeding to withdraw the balloon.If resistance is still felt during post procedure withdrawal of the catheter, it is recommended to remove the balloon catheter and guidewire/ introducer sheath as a single unit.Do not continue to use the balloon catheter if the shaft has been bent or kinked.¿ the information available does not suggest a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
