(b)(4).Device evaluation: the report that the guide wire was damaged during insertion was confirmed.Returned was a radial artery (ra) ca theorization device consisting of a guide wire, advancer tube, and needle.The catheter was not returned.The handle to advance the guide wire was fully retracted into the advancer.The guide wire was unraveled at the distal end and the coil wire was protruding from the distal tip of the needle.The sample was examined microscopically.The distal weld was missing from the coil wire.There was damage inside the needle bevel and a depression on the outside of the cannula.Dried blood was observed inside the needle.Attempts to advance the guide wire out of the needle were unsuccessful and resulted in additional damage to the wire.The instruction booklet provided with the kit describes suggested techniques to minimize the likelihood of guide wire damage during use.It contains the precaution not to force feed the guide wire if resistance is encountered while advancing the guide wire.It also contains the warning not to retract the guide wire against the edge of the needle while in the vessel to minimize the risk of guide wire damage.A review of the device history records did not reveal any manufacturing related issues.Based on the condition of the other remarks: sample and the report of difficulty during insertion, operational context caused or contributed to this event.No further action will be taken.
