(b)(4).The report of an unraveled guide wire was confirmed through complaint investigation.The guide wire was observed to be unraveled towards the distal end.Despite the damage, the guide wire met all relevant dimensional requirements, and a device history record review did not reveal any relevant findings.Arrow guide wires of this size are designed and manufactured to withstand a tensile force of 2.0 pounds force.The selected insertion site and patient anatomy may present a tortuous path that could contribute to the possibility of guide wire kinking.Guide wire breakage may occur if a force greater than the design specification is applied during removal.Regardless of these circumstances, the root cause cannot be determined without the catheter and catheterization device also returned for analysis.Teleflex will continue to monitor and trend for reports of this nature.The ifu provided with the kit informs the user, "to reduce the risk of guidewire damage, do not retract guidewire against edge of needle while in vessel".

It was reported that: the rrt was attempting to insert a radial arterial line in the ccu using the above-named guidewire set.She c hecked the set for the ability to withdraw the guidewire prior to starting the procedure, as per policy.She inserted the needle into the patient's wrist area and obtained arterial blood flash in the viewing window, indicating that the needle was correctly placed in the patient's artery.She advanced the guidewire without issue but then was unable to advance the catheter over the needle.She attempted to withdraw the guidewire prior to removing the needle and discontinuing the attempt, however she felt significant resistance when attempting to withdraw the guidewire.Despite careful repositioning, she was still experiencing resistance from the guidewire and managed to withdraw the wire against the resistance.When the guidewire was removed it had split into two pieces and had a curled and slightly unraveled appearance.There was no evidence of hematoma or injury at the site.After the procedure was completed, she notified the mrp, who determined it best to complete a ct scan of the patient's arm to determine whether there were any fragments left behind.Fortunately, there was nothing visualized and there appears to be no other sequelae of this event.The patients curr ent condition is reported as fine.
