As reported, the physician was not able to reinsert the powerflex pro 6mm 15cm balloon through a 6f 55cm non-cordis sheath because the balloon would not rewrap.Physician had previously used the balloon for one inflation and struggled to remove the balloon through the sheath.The device was removed intact from the patient.The case was completed with a new unknown balloon.There was no reported injury to the patient.The device was stored at proper room temperature on a cart.The device was stored per the instructions for use (ifu).There was no difficulty removing the product from the hoop, protective balloon cover, 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 was prepped per the ifu and was prepped normally.The device was able to maintain negative pressure.The intended lesion was in the superficial femoral artery (sfa).The lesion was noted to have moderate calcification.The vessel did not have any tortuosity.The device was not being used to treat a chronic total occlusion (cto).There was no difficulty advancing the balloon through the vessel and the balloon crossed the lesion without difficulty.The device was never in an acute bend.The balloon was re-prepped before attempting to insert for the second time.Deflation of the balloon was longer than desired as it took 15-20 seconds to deflate.The balloon was deflated by puling negative pressure multiple times.The balloon was not deflated completely but it was enough to remove from the patient.The non-cordis inflation device was filled with a 70:30 saline/contrast ratio.The same inflation device was used successfully with other devices during the procedure.The device will be returned for evaluation.

therefore, it is assumed by these findings along with the interactions between the concomitant devices, may have contributed to the failures reported as evidenced by device analysis.Handling and procedural factors that are not limited to, patient¿s anatomy, lesion¿s severity in calcification, and/or stenosis were likely additional factors to the events as the bulging of the balloon material is suggestive of forceful handling during removal.According to the safety information in the instructions for use ¿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.Flush the ¿thru¿ lumen with sterile heparinized saline or a similar isotonic solution.Place the prepared catheter over a prepositioned guidewire and advance the tip to the introduction site.If resistance is met during manipulation, determine the cause of the resistance before proceeding.Consider the use of systemic heparinization.Flush all devices entering the vascular system with sterile heparinized saline or similar isotonic solution.If resistance is met during manipulation, determine the cause of the resistance before proceeding.If strong resistance is met during advancement or withdrawal of the catheter, discontinue movement and determine the cause of resistance before proceeding.If the cause of resistance cannot be determined, withdraw the entire system.¿ 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.
