One duodecapolar, spiral loop, inquiry optima diagnostic catheter was received for evaluation.Visual inspection revealed multiple bends on the shaft proximal to the spiral loop.Additionally, the strain relief was bent and the catheter shaft was twisted and kinked proximal to the spiral loop/shaft transition.A tear in the catheter shaft was noted 2.10¿ proximal to the spiral loop/shaft transition exposing the spring body.The catheter deflected when actuating the steering mechanism; however, did not deflect in the correct shape and did not meet specification, due to the aforementioned condition of the shaft.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.Further analysis revealed the cause of the kink and tear in the shaft is consistent with damage during use.
