Event or Problem Description
|
|
A 6mm x 10cm 150 saber percutaneous transluminal angioplasty (pta) balloon catheter burst at 10 atmospheres (atm) inside the patient.There was no reported patient injury.The device was discarded.The lesion was calcified with no vessel tortuosity.It was not a chronic total occlusion (cto).There was no difficulty removing the complaint balloon from the forming tube.There were no kinks or other damages noted prior to inserting the product the product into the patient.The device prepped normally.The contrast to saline ratio was 50/50.The same indeflator was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve and while inserting the balloon through the guide catheter.There was no difficulty advancing the balloon catheter through the vessel.The maximum inflation pressure was 10atm.The balloon catheter did not kink while being used and was easily removed.Patient demographics including medical history and the reason for the procedure were requested but were not available.
