Complaint conclusion: during the use of a powerflex pro balloon (8mm4cm 135), it was reported that under the normal operating pressure, the balloon had a longitudinal separation in vascular lumen. failed to normal expansion lesion. there was no report of patient injury.Multiple attempts to gather additional information have been made and have been unsuccessful. the device was not returned for analysis.A device history record (dhr) review of lot 17491553 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event. the reported ¿balloon separated - in-patient (peripheral)¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Additional information and vessel characteristics were not provided.According to the instructions for use (ifu), ¿if resistance is met during manipulation, determine the cause of the resistance before proceeding.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.Do not advance or retract the catheter unless the balloon is fully deflated under vacuum.Remove the vacuum (do not apply pressure) and carefully withdraw and remove the catheter.Note: gentle counterclockwise rotation of the balloon may ease withdrawal from the sheath or from the percutaneous entry site.If the balloon cannot be withdrawn through the sheath, withdraw the catheter and sheath as a unit.¿ neither the dhr nor the information available suggests a design or manufacturing related cause for the reported event; therefore, no corrective/preventive action will be taken.
