(b)(6).(b)(4).The analysis of the returned device revealed that the pebax coating detached and the corewire broke at 2.50 cm from the ptfe flare at the distal tip.Additionally, the guidewire was observed bent at distal section.Based on the investigation results, it is probable that anatomical/procedural factors like interaction with other devices or while the device was advancing through the working channel could have generated the failures encountered.However, the outer diameter dimensions were found within specification.Therefore, the most probable cause of this complaint is adverse event related to procedure if the event occurred during the procedure and the device had no influence on event.A dhr (device history record) review was performed and no deviation was found.
