During use in patient, the powerflex pro 6x6 cm x135 cm 5fr 0.035" balloon would not deflate completely causing difficulty of the balloon to be removed from the competitor's sheath.There was no patient injury.The physician removed the sheath with the balloon inside and completed the procedure.The powerflex pro balloon was prepped per the instruction for use with no anomalies noted during prep.There were no difficulty removing the product from the hoop, protective balloon cover, stylet or any of the sterile packaging components.A constant and dedicated saline source was utilized through the balloon during insertion during prep.There were no kinks or other damages noted prior to inserting the products into the patient.The balloon was able to entered the 6 fr competitor's sheath well, but then it was not possible to remove the balloon from the sheath as there was a problem with deflating the balloon completely.The physician removed both the sheath with the balloon inserted from the patient and another competitor's sheath was used to continue the procedure.The device is available for analysis.No other information was provided.
