Block h6: imdrf code a041001 captures the reportable event of balloon pinhole.Block h10: investigation results: the returned cre pulmonary dilatation balloon was analyzed, and a visual examination found that the balloon and catheter of the device had no damages.Functional analysis was performed, and the balloon was inflated without a problem.However, the balloon would not hold pressure due to a pinhole in the balloon (distal section) located approximately 16 mm from the tip.Media inspection was performed, and based on the video provided by the customer it was possible to observe the balloon with a pinhole.Microscopic inspection found a pinhole located approximately at 16 mm from the tip of the device.No other problems with the device were noted.With all the available information, boston scientific concludes the reported event off balloon pinhole can be confirmed.The conclusion is acceptable because, after the product analysis, it was found that the balloon had a pinhole located approximately at 16 mm from the tip of the device.The pinhole found is likely to have occurred due to procedural factors such as excess of pressure or interaction with other devices.Also, it is possible that interaction with a sharp surface during/previous the procedure could have caused the problem found on the distal section of the balloon.Therefore, the most probable root cause is an adverse event related to procedure.A labeling review was performed and, from the information available, this device was not used in accordance with the instructions for use (ifu)/product label.
