(b)(4).Returned product consisted of the hypotube and shaft of a coyote es balloon catheter in two pieces, the hub not received.The shaft, hypotube, and bonds were microscopically and visually examined.There is tip damage.The shaft was completely separated 26.5cm from the tip.As the shaft is completely circumferentially torn it is consistent with the reported damage.There are numerous hypotube and shaft kinks.There is no evidence that the device failed to meet applicable product specifications prior to shipment.The most probable root cause is operational context as device performance was limited due to anatomical/procedural factors.(b)(4).
