Device evaluated by manufacturer: visual inspection of the device revealed a severe kink on the proximal side of ring 3 and a bend n the main body tubing.Dried body fluids were found on the handle, main body tubing, and o the distal end.The tension control knob functioned properly on both lock and unlock positions.The steering knob did not alter the distal end curve when turned clockwise.X-ray imaging revealed a broken center support and steering wire.The distal end was dissected and inspection confirmed the broken enter support.It has cu the kevlar wrap, puncture the sheath, and then pierced the cooling lumen.The cooling lumen¿s location above the center support prevented perforation of the main body tubing.The center support also has a bend approximately 30mm from the end of the distal tip.The right steering wire is broken at the same location as the center support, and has retracted back toward the handle.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion was unable to be determined.(b)(4).
