Block h6: problem code 1074 captures the reportable event of balloon burst.Block h10: investigation result.A visual examination of the returned complaint device found that the balloon was not folded which indicated that the device was subjected to positive pressure.A microscopic examination was performed and a partial balloon circumferential tear was noticed located in the distalal section of the proximal sleeve.No other issues were noted in the balloon material, markerbands,and tip of the device.A visual and tactile examination identified no kinks or damage to the shaft.This failure is likely due to factors or conditions related to the procedure during the use of the device, such as difficult patient anatomy such as kidney stones that could have caused the balloon to rupture.With the compromised balloon refold the device would have encountered resistance at the sheath on removal from the patient.The balloon partial circumferential tear was most probably due to the user applying excessive tensile force when attempting to withdraw the device through the sheath on removal.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
