As reported, the 5f 4 x 4 x 40 powerflex p3 percutaneous transluminal angioplasty (pta) balloon catheter (bc) was used during shunt plasty, but it ruptured with nominal pressure.The device was removed, and the patient was treated with another balloon catheter (unknown).There was no difficulty removing the product from the hoop, removing the protective balloon cover or difficulty removing the stylet or any of the sterile packaging components.There were kinks or other damages noted prior to inserting the product into the patient.The device prepped normally.The same indeflator was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve.There was no resistance/friction while inserting the balloon through the guide catheter.The lesion calcified was a little.The vessel was a little tortuous.There was 20-30% percentage of stenosis.The device was not used for a chronic total occlusion (total occlusion >3 months).There was no difficulty advancing the balloon catheter through the vessel.There was no difficulty crossing the lesion.The catheter was never in an acute bend.The plunger was depressed into the syringe/indeflator when trying to inflate.The user able to depress the plunger into the syringe/indeflator when trying to inflate.The balloon inflated normally.The balloon did burst.The balloon did not seem to ¿stick¿ to a stent.The balloon did not re-wrap because the balloon ruptured.The balloon catheter did not kink while being used.The balloon catheter was removed easily.The product was removed intact (in one piece) from the patient.No patient injury occurred.The patient was discharges.The device will not be returned for analysis as it was discarded by the site.

After further review of additional information received the following sections have been updated accordingly g4,g7,h1,h2,h3 and h6.As reported, the 5f 4 x 4 x 40 powerflex p3 percutaneous transluminal angioplasty (pta) balloon catheter (bc) was used during shunt plasty, but it ruptured with nominal pressure.No patient injury occurred.The device was removed, and the patient was treated with another balloon catheter (unknown).There was no difficulty removing the product from the hoop, removing the protective balloon cover or difficulty removing 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 prepped normally.The same indeflator was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve.There was no resistance/friction while inserting the balloon through the guide catheter.The lesion had little calcification and tortuosity.There was 20-30% percentage of stenosis.The device was not used for a chronic total occlusion (total occlusion >3 months).There was no difficulty advancing the balloon catheter through the vessel.There was no difficulty crossing the lesion.The catheter was never in an acute bend.The plunger was depressed into the syringe/indeflator when trying to inflate.The user able to depress the plunger into the syringe/indeflator when trying to inflate.The balloon inflated normally.The balloon did burst.The balloon did not seem to ¿stick¿ to a stent.The balloon did not re-wrap because the balloon ruptured.The balloon catheter did not kink while being used.The balloon catheter was removed easily.The product was removed intact (in one piece) from the patient.The patient was discharged.The product was not returned for analysis as it was discarded by the facility.A product history record (phr) review of lot 82193700 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 calcification and stenosis may have contributed to the events reported by the customer.The intended use was a shunt angioplasty, arteriovenous shunts are often scarred and fibrous in nature and therefore often resistant to balloon expansion increasing the likelihood of damage to the balloon.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 ¿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.¿ 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.
