Complaint conclusion: as reported, a 7mm x 4cm x 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter crossed the lesion and inflated; however, it ruptured within nominal burst pressure (nbp).There was no reported patient injury.The target lesion was the iliac artery.The lesion had severe calcification.The device was removed from the patient¿s body and replaced with the same size unknown balloon catheter.A plain old balloon angioplasty (poba) was performed and the procedure was completed.The product was removed intact (in one piece) from the patient.Additional procedural details were requested but are unknown.The device was not returned for analysis as it was discarded by the facility.A product history record (phr) review of lot 82187305 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.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 severe calcification may have contributed to the reported event, as it is known that calcium may damage balloon material.However, without return of the product for analysis, it is difficult to draw a clinical conclusion between the device and the reported event.According to the safety information in the instructions for use ¿if resistance is met during manipulation, determine the cause of the resistance before proceeding.Balloon pressure should not exceed the rated burst pressure.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.Use only the recommended balloon inflation medium.Never use air or any gaseous medium to inflate the balloon.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.¿ 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.
