This report is being submitted as follow up no.1 to provide additional information in section b5, to update section d9, to update section h3, and to provide the completed investigation results.One 6fr glidesheath slender guidewire and needle were returned for product evaluation.Visual inspection revealed that there was a significant bend on the needle and the guidewire.The guidewire was placed inside a plastic hoop and an extensive bend was seen on the wire where the hoop ended.Similarly, the needle was also extensively bent.Blood like substances were seen inside the needle.The floppy end weld of the guidewire was viewed under microscope and was intact.Dimensional testing was performed.Measurements of the guide wire were taken, and the diameter of the wire was 0.510 mm which was within the manufacturer specification of 0.51-0.54 mm.Functional testing was performed.The guidewire could not be inserted into the needle since the needle and the guidewire was extensively bent.Uncoiling was not observed on the guidewire floppy end weld.The complaint can be confirmed for guide wire mobility.The guidewire could not be inserted into the needle and uncoiling was not observed on the guidewire floppy end weld.Based on the investigation, the cause of the event could be due to off- axis brute forces that led to deformation of the guidewire and the needle which prevented the guidewire to advance through the needle.The device was in a conforming state when released from terumo control.There is no indication that any manufacturing issues may have led to this event.Currently no action is recommended since this risk evaluation is within the predetermined limits in the fmea.
