Qn#(b)(4).Device evaluation: the complaint of a kinked guide wire during insertion was confirmed.Returned by the customer was one guide wire with no additional components.A visual examination of the guide wire revealed an opened j-bend.A manual tug test confirmed that both welds remain intact.The guide wire measured 601 mm in length.The outside diameter (od) measured.078 mm.The returned guide wire was within specification for length and od per guide wire graphic length: 596 - 604 mm and od: 0.788- 0.826 mm).Microscopic examination revealed off-set coils at 1.3 cm from the distal tip with one kink at 2.3 cm.The instructions for use describe suggested techniques to minimize the likelihood of guide wire damage during use.A device history records review was performed and 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.
