Manufacturing site: asahi intecc.(b)(4).Single reporter exemption #e2015028.The importer report number used for this report was generated from the importer registration number, current year, and sequential number that match the manufacturer report number.Device evaluation could not be performed because the device was not returned.Lot history review revealed no anomaly relating to the reported event.No other similar product experience report was received from this lot.Reviewing of production records found no indication of product deficiency.It was presumed that pushing, tensional, and/or torsional stress generated during wire manipulation in attempts to cross the target lesion might be inadvertently applied while the distal segment of the guide wire was being trapped in the lesion.When the applied stress exceeded the product's design limit, it likely led the wire to become separated.Instructions for use (ifu) states: warnings: if any resistance is felt due to spasm or the guidewire being bent or trapped while operating the guidewire in the blood vessel or removing it, do not move or torque the guidewire.Stop the procedure.Determine the cause of resistance under fluoroscopy and take appropriate remedial action.If the guidewire is moved excessively, it may break or become damaged, which may cause blood vessel injury or result in fragments being left inside the vessel; and, malfunction and adverse effects- separation or breakage of the guide wire.
