It was reported that during removal of the guide wire from the female patient's jugularis interna, the guide wire unraveled.As a result, a new kit was opened and used; however, the same issue occurred.A delay was reported, however, there was no additional harm to the patient due to this delay or as a result of this occurrence.The patient involved was a (b)(6) female with a height of (b)(6).

Qn#(b)(4).This report is for the first in a series of two consecutive product problems with the same patient.The second issue has been reported under mdr # 3006425876-2016-00217.Device evaluation: the reported complaint of the guide wire broke upon removal was confirmed.The customer returned one guide wire.Visual examination revealed the guide wire is unraveled from the distal end and no kinks were observed.Microscopic examination revealed a discoloration and necking of the core wire in the area of the break.Discoloration at the broken end of the core wire is consistent with proximity to a weld.Further microscopic examination revealed that the distal weld was separated and missing from the end of the coil wire and that the proximal weld was full and spherical.A manual tug test confirmed that the proximal weld remains intact.The broken core wire measured 685mm in length, which is within the specification of 679 mm - 687 mm per guide wire drawing, indicating that no pieces of the core wire are missing.The diameter of the guide wire measured 0.864 mm, which is within the specification of 0.838mm - 0.877 mm per guide wire drawing.Other remarks: the instructions for use describes suggested techniques to minimize the likelihood of guide wire damage during use.The instructions state that if resistance is encountered when attempting to remove the guide wire after catheter placement, the guide wire may be kinked about the tip of the catheter within the vessel.In this case it is recommended to withdraw the catheter relative to the guide wire about 2-3 cm and then attempt to remove the guide wire.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.The device history records were reviewed with no findings relevant to this complaint.No manufacturing defects were found during this investigation.A risk evaluation was completed for this complaint.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.
