(b)(4).Device evaluated by mfr: the device was returned for analysis.Visual inspection revealed that there are two kinks located approximately 5cm and 7.3cm from the distal tip.A section of the ring 1 seal is missing from the proximal side of the electrode.It appears the section of the seal had been torn away; the edges are clean.However, there is enough adhesive remaining on the electrode and insulation shaft to complete the electrode edge seal; the seal itself is not compromised.Dimensional inspection was done.The tip motion was evaluated against curve template.Both right and left curve tests failed.X-ray showed the center support is bent in two places.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion is design specification as the device problem was traced back to the design specifications.(b)(4).
