Investigation summary: customer returned (14) 3/10cc, 12.7mm, 30g syringes (4 in an open poly bag, 10 in a sealed poly bag) from lot # 6221866.Customer states that the plunger rod is difficult to move and the stopper turns sideways while injecting.All returned syringes were examined and one sample exhibited a deformed stopper in the barrel that could cause the plunger rod to be difficult to move.The noted sample exhibiting the deformation of the stopper was cycle tested without notable findings at this time.Additionally, the stopper was disassembled from the syringe barrel and was noted to retain its deformed configuration.A review of the device history record was completed for batch # 6221866 all inspections were performed per the applicable operations qc specifications.There were zero (0) notifications noted that pertained to the complaint.Based on the samples / photo(s) received the investigation concluded: confirmed: bd was able to duplicate or confirm the customer¿s indicated failure.This condition is referred to as a rolled stopper which can occur during the assembly process, when the plunger rod is being assembled in the barrel and there is inadequate (not enough) lube present in the barrel id (inner diameter) and or the stopper itself does not have enough lube on it.As a result, the stopper does not move freely in the barrel and can become stuck and deformed.There is also the possibility that the stopper starts out being misaligned on the end of the plunger rod and then gets rolled as it is being inserted inside the barrel.Rolled stoppers can also be caused by partially peeling off the stopper before insertion into the syringe barrel.As per supplier, improper stacking of rubber sheets in autoclave cart, causing pinching/deformity.Probable root cause could be a supplier related issue or a misalignment during assembly of the plunger rod/stopper into the syringe barrel.(b)(4) was initiated by the holdrege plant to address deformed/damaged stoppers and their associated root cause(s).Batch# 6221866 was manufactured prior to initiation of this capa.No additional actions deemed necessary at this time.
