A 7f 25 x 40 110 maxi ld percutaneous transluminal angioplasty (pta) balloon catheter did not inflate upon inflation during a procedure and balloon rupture was confirmed.There was no reported patient injury.The device was not used for a chronic total occlusion (cto).The lesion was mildly calcified.There was almost no vessel tortuosity noted.There was no stenosis.It was then replaced with a new unknown balloon catheter and the procedure was completed.The device was stored and handled as per instructions for use (ifu).There was no difficulty removing the product from the hoop, the protective balloon cover, 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 was prepped normally (i.E.Maintain negative pressure) per ifu.The same indeflator was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve or the guide catheter.There was no unusual force used at any time during the procedure.The balloon catheter was removed easily and intact (in one piece) from the patient.Other additional procedural details were requested but were unknown.The product was not returned for analysis as it was discarded due to suspicious infectious disease.A product history record (phr) review of lot 82156670 revealed no anomalies or non-conformance's during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon burst¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.With the limited amount of information available and without the return of the product or films of the procedure it is difficult to draw a clinical conclusion between the device and the event.However, vessel characteristics of calcification may have contributed to the reported event as calcium is known to damage balloon material.According to the safety information in the instructions for use ¿note: the rated burst pressure is printed on the package label.In vitro testing has shown that with 95% confidence, 99.9% of the balloons will not burst at or below the rated pressure.Balloons should not be inflated in excess of the rated burst pressure.Prior to angioplasty, the catheter should be examined to verify functionality and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Carefully advance the catheter through a sheath or through the percutaneous entry site.Note: gentle counterclockwise rotation of the balloon may ease introduction through the sheath or percutaneous entry site.Note: perform all further catheter manipulations under fluoroscopy.Carefully advance the catheter to the selected site.Caution: if strong resistance is met during advancement or withdrawal of the catheter, discontinue movement and determine the cause of resistance before proceeding.If the cause of resistance cannot be determined, withdraw the entire system.¿ 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.
