Manufacturer Narrative

Product evaluation: failure analysis for fiber 0010-2090-752h-(b)(4): the fiber cap exhibits signs of melting which formed a hole from the surface to the bevel edge; there is some white unknown substance noted inside the distal end of fiber cap; the glass cap exhibits devitrification at the output area, and detritus adhesion around output area; the heat shrink tubing exhibits minor scratch marks; the fiber appears blackened near the heat shrink tubing open end.Based on device analysis, the potential for forward firing may exist.Probable root cause: based on the device analysis, the probable root cause of the failure is: heat accumulation.Cap wear was accelerated due to anatomical/procedural factors (tissue contact and technique) encountered during the procedure which would limit the performance of the fiber.
