A pinhole was noted on the balloon of 6mm x 4cm x 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheter (bc).The balloon was removed intact and the procedure was completed with a non-cordis device.There was no reported patient injury.The product was returned for analysis.One non-sterile powerflex extreme 6x4 80cm catheter was received for analysis coiled inside a plastic bag.The balloon was received deflated.Per visual analysis, no anomalies were observed in the returned device.Per microscopic analysis, the unit was inspected under vision system and no anomalies observed.Per functional analysis, leak test was performed.Water was applied to the catheter and the balloon was successfully inflated.No anomalies found.A product history record (phr) review of lot: 82183780 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon leakage¿ could not be confirmed during device analysis.Functional analysis was performed, and the balloon successfully inflated with no anomalies noted to the device.The exact cause of the event reported could not be determined during analysis.The device performed as intended by successful inflation; therefore, it is likely that procedural factors and handling of the device, contributed to the event reported by the customer.According to the safety information in the instructions for use ¿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/preventive action will be taken at this time.
