The oad was received at csi for analysis.Analysis revealed adhered biological material on the driveshaft crown section.The material caused resistance when passing a wire through.Analysis did not identify any damage that may have contributed to the accumulating material.The morphology and exact root cause of the accumulated biological material is unknown.When tested the device functioned as intended.The device history record for this oad lot number has been reviewed.No issues or discrepancies were noted during this review that would have contributed to the reported event.The device met material, assembly, and quality control requirements.H6 code 4247: suggested code is biological material present on device.Csi id: (b)(6).
