As reported, the balloon of a 5mm x 4cm 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter ruptured within its nominal pressure at 4 atmospheres (atm).As a result, the 5mm x 4cm 80cm powerflex pro pta balloon catheter was replaced with an unknown 5mm x 4cm balloon catheter which was used without issue.This was followed by the implantation of an unknown stent to complete the procedure.There was no reported injury to the patient.This was during an interventional procedure to treat a lesion in the iliac artery in which an ipsilateral retrograde approach was used.A non-cordis guidewire was used during this procedure and was able to cross the lesion.Additional information as requested but was not provided.The device has now been returned.

Complaint conclusion: the balloon of a 5mm x 4cm 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter ruptured within its nominal pressure at four atmospheres (4atm).As a result, the 5mm x 4cm 80cm powerflex pro pta balloon catheter was replaced with an unknown 5mm x 4cm balloon catheter which was used without issue.This was followed by the implantation of an unknown stent to complete the procedure.There was no reported injury to the patient.This was during an interventional procedure to treat a lesion in the iliac artery in which an ipsilateral retrograde approach was used.A non-cordis guidewire was used during this procedure and was able to cross the lesion.Additional information as requested but was not provided.A non-sterile powerflex pro 5mm x 4cm 80cm unit was received for analysis inside a plastic bag.Per visual analysis, neither burst, nor rupture or any damage that could cause the reported failure could be observed.Per functional analysis a lab sample inflator/ deflator device partially filled with water was attached to the inflation lumen of the unit and positive pressure was applied.The balloon was instantly inflated.Next, negative pressure was also applied, and the powerflex was immediately deflated as expected.No anomalies were found.A product history record (phr) review of lot 82222584 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¿ was not confirmed through analysis of the returned device.The exact cause of the reported event could not be determined during analysis.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 review nor the product analysis suggests that the event experienced by the customer could be related to the manufacturing process; therefore, no corrective/preventive action will be taken at this time.
