(b)(4) device evaluation: the reported complaint of the guide wire became kinked during insertion was confirmed.
The customer returned one guide wire.
Visual examination revealed the distal end of the guide wire was kinked.
An offset coil was observed within the j-bend, and just beyond the j-bend the wire was kinked to a 90 degree angle with biological material observed between the coils.
Two additional kinks were also observed.
The kinks were measured at 1.
5, 2.
1, 3.
5 and 4.
2 cm from the distal end.
Microscopic examination confirmed that both welds were full and spherical.
A manual tug test confirmed that both welds remain intact.
The guide wire measured approximately 601 mm in the total length and exhibited an outside diameter (od) of 0.
799 mm.
The returned guide wire was within specification for length and od.
Instructions for use describe suggested techniques to minimize the likelihood of guide wire damage during use.
A device history record review did not reveal any manufacturing related issues.
Since the guide wire is always inserted through another component such as an introducer needle, ars syringe or introducer catheter and none of these components were returned, the probable cause of this issue could not be determined.
No further action will be taken.
