Imdrf device code a041001 captures the reportable investigation result of balloon pinhole.Investigation results the returned cre pulmonary dilatation balloons 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 pinhole in the distal section of the balloon.Microscopic inspection found had a pinhole located approximately at 29 mm from the tip.No other problems with the device were noted.With all the available information, boston scientific concludes the reported event of balloon would not inflate was confirmed.The pinhole found in the balloon is likely to have occurred due to factors encountered during the procedure: excess pressure, interaction with other devices, or patient anatomy.It is possible that factors encountered during the procedure, such as the interaction with any surface during the procedure could create friction on the balloon and cause to failure to inflate.Therefore, the most probable root cause is adverse event related to procedure.A labeling review was performed and, from the information available, this device was used per the directions for use (dfu) / product label.
