As reported, the balloon of an 8mm x 4cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter ruptured during a post-dilation inflation.As a result, an 8mm x 4cm non-cordis balloon catheter was used as a replacement to complete the procedure.There were no reported injuries to the patient.Additional information was requested but was unavailable.The device will not be returned for evaluation.

After further review of additional information received the following sections have been updated accordingly: b4, d9, g3, g6, h1, h2, h3, h6, and h10.Complaint conclusion: as reported, the balloon of an 8mm x 4cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter ruptured during a post-dilation inflation.As a result, an 8mm x 4cm non-cordis balloon catheter was used as a replacement to complete the procedure.There were no reported injuries to the patient.Additional information was requested but was unavailable.The device was not returned for analysis.A product history record (phr) review of lot 82285959 revealed no anomalies or non-conformances 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.The device ruptured during post-dilation, calcification is known to damage balloon material; it is likely damage occurred during crossing or in the attempt to inflate the balloon at the lesion.However, without the return of the device for analysis, and with the limited amount of information provided, it is difficult to draw a clinical conclusion between the device and the event reported.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.
