(b)(4).Device evaluation: the actual device was returned for evaluation.Reliability engineering evaluated the device and the reported condition was not duplicated or confirmed.Therefore, an assignable root cause was not determined.However, during evaluation it was observed that there was black discoloration on the tip which indicates insufficient irrigation during the procedure contrary to dfu (directions for use).A dimensional assessment was performed which determined that all measurable features met specifications.A functional test was performed and this burr exhibited a normal cut rate for this burr design.This burr design employs the use of a primary on the edge of the cutting flutes which is intended to make them less aggressive than a standard fluted burr.They are used in proximity of the facial nerve during ent procedures where great care must be taken not to damage the nerve.The assignable root cause was determined to be due to component damage cause by use error.If additional information should become available, a supplemental medwatch report will be sent accordingly.
