(b)(4).The customer returned one arterial catheterization device (without the catheter) and the lidstock from a ra-04220 kit for evaluation.The spring-wire guide (swg) was kinked toward the distal end.Microscopic examination confirmed the kink and revealed offset coils and biological material at the same location as the kink.The swg was kinked 18 mm from the distal end of the swg.The outer diameter of the swg was measured and was found to be within specification.A device history record review was performed and no relevant findings were identified.The instructions-for-use (ifu) that are packaged with this product suggest that the catheterization device be removed by firmly holding the introducer needle hub in position and advancing the catheter forward, with a slight rotating motion, over the swg into the vessel.The ifu also warns not to retract the swg against edge of needle while in vessel to minimize the risk of swg damage.The customer reported issue of the arterial catheter and swg kinking during use was confirmed during the complaint investigation.The returned catheterization device was visually examined and the swg was found to be kinked toward the distal tip.The catheter was not returned for evaluation.Dimensional inspection was performed on the swg and no issues were identified.A device history record review was performed and no relevant findings were identified.Without the catheter, a probable cause of this issue could not be determined.Teleflex will continue to monitor and trend for reports of this nature.
