Investigation: bd was able to verify the reported issue of needle retraction failure.The received sample needle was partially retracted.The possible cause for the problem was verified during the plug placement step, where the rod, which is inserted into the inside of the grip, could collide with the plug, causing a damage on this component.This damage prevents the movement of the button during its activation, thus preventing retraction of the cannula.Although there was already an established alignment method to avoid this problem during the process, there was no sensor that would ensure that the part would be discarded if the rod hit the grip.The change of the rod sensor program was performed, so that in case of a contact of the rod with the grip the part is discarded.Dhr review: a review of the device history record was completed for sub-assembly #8607679 lot 8057538 manufactured from 02-mar-18 to 29-mar-18 used in claimed lot 8086910.The batch was analyzed for "needle retraction" and ¿part activation¿ tests, and it was not evidenced record of failure of activation of the part during the analysis of these lots.
