Age at time of event: 18 years or older.(b)(4).The device was returned for evaluation.Visual inspection of the device observed that the distal tip was broken at 327.8cm approximately from the proximal end; also, the spring tip was not returned.Moreover, the body was kinked at 114.5cm approximately.From the proximal end.All the outer diameter measurements are within the specifications.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
