The investigation of the complaint was limited because no sample was returned.The complaints trend review identified that there is no trend of confirmed complaints in relation with this issue.Due to the fact that reported issue occurred during procedure it is the most probable that the catheter was cut off by tuohy needle when catheter was pulled back which is in conflict with ifu l6306 rev.100, page 4, point 4.1: "never pull back the catheter through the epidural tuohy needle as this can result in the catheter being cut and left in the epidural space.If catheter insertion difficulties are encountered, the epidural tuohy needle and catheter should be removed carefully together as a single unit, and the procedure repeated." the problem source of the reported product problem was unknown.A root cause was not established.
