It was reported the procedure was being performed in the medical ward.
When the physician was inserting the guide wire, resistance was met which resulted in the wire kinking.
As a result, everything was removed and a new kit was used for the procedure.
There was a delay in treatment with no patient harm and no patient death or complications reported.

Qn#(b)(4).
Device evaluation: the report that the guide wire kinked during use was confirmed.
One 2-lumen 7fr x 20 cm catheter with a guide wire inserted through it, was returned.
A dilator, tray and lidstock were also returned.
Additionally, the customer provided three photographs showing the returned components inside a plastic bag.
The guide wire / catheter assembly was kinked 1.
5 and 17 cm below the catheter juncture hub.
The guide wire was protruding 2 cm from the proximal end and 24 cm from the distal end of the catheter.
The guide wire was removed from the catheter.
A manual tug test determined that both welds are intact with the core wire.
Kinks were observed in the guide wire body located 28 and 43 cm from the j-tip weld.
The kinks correspond with those observed in the guide wire / catheter assembly.
The guide wire graphic specifies an outside diameter of.
788/.
826 mm and a length of 600 +/-4 mm.
The guide wire length was confirmed to be consistent with the graphic.
The outside diameter measured.
813 mm, which met specification.
After removal of the guide wire, the catheter remained kinked 1.
5 cm below the juncture hub.
A lab inventory.
032" guide wire, other remarks: with a measured diameter of.
804 mm, was passed through the catheter without resistance.
The instructions for use describes suggested techniques to minimize the likelihood of guide wire damage during use.
The device history records were reviewed and did not reveal any manufacturing related issues.
No manufacturing defects were found during this investigation.
Based on the observed damage and information provided, operational context caused or contributed to the event.
No further action will be taken.
