Event Description
|
It was reported a second kit was obtained.
The physician inserted the guide wire through the needle.
When removing the guide wire it unraveled.
He felt the wire became caught on the needle and could not withdraw without removing the wire and needle.
As a result, a third kit was obtained and placed successfully.
There was no patient death or complications reported.

Manufacturer Narrative

(b)(4).
Device evaluation: it was reported that the physician inserted the spring wire guide through the needle.
When removing the guide wire it unraveled.
He felt the wire became caught on the needle and could not withdraw without removing the wire and needle.
The issue was confirmed.
One guide wire inserted through a dilator was returned.
The introducer needle involved in the incident was not returned.
The guide wire had several bends in guide wire body and was unraveled starting 1.
5 cm from the j-tip.
A manual tug test confirmed that the proximal (straight-end) weld remains intact with the coil/core wires.
Microscopic inspection determined that the core wire was separated adjacent to the distal weld.
The weld appears full and remains attached to the unbroken coil wire.
The guide wire graphic specifies the length at 454 +/- 4 mm and the outside diameter at.
838/.
877 mm.
The length of the broken core wire was confirmed to be consistent with the graphic; therefore no pieces appear to be missing.
The diameter of the guide wire measured 0.
854 mm, which was within specification.
The dilator body was curved and the tip was pushed back.
The inside diameter of the dilator tip could not be measured because of the damage.
The undamaged proximal end of the guide wire was inserted through the dilator other remarks: without resistance.
The instructions for use describes suggested techniques to minimize the likelihood of guide wire damage during use.
The instructions caution that withdrawing the guide wire against the needle bevel or use of excessive force during removal could damage or break the wire.
A device history record review was performed and did not reveal any manufacturing related issues.
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.
Based on these circumstances, operational context caused or contributed to the event.
No further action will be taken.
