It was reported that the needle of the bd insyte¿ autoguard¿ was bent, which is not an mdr reportable malfunction.However, during the course of the sample investigation, it was discovered that there was an issue with retraction failure/safety mechanism failure.The needle did not retracted after use.There was no report of injury or further medical intervention.

One sample unit was received for evaluation by our quality engineer team.Upon visual/ microscopic examination, the needle was observed partially retracted into the safety barrel, the exposed needle was off center, and damage was present on the grip of the barrel, causing the partial retraction.The needle was repositioned outwardly, the needle was not curved or bent.The damaged grip was determined to be a result of a misalignment in the manufacturing process.The plug probe and load barrel stations have the ability to become misaligned and produce the type of damage observed.Inspections are performed regularly by operators to ensure errors are identified.Device/batch history record review could not be performed as the lot number for this incident is unknown.The defect needle bent; as stated as the reported code was not confirmed with the returned unit.The damage to the grip component prevents a full retraction.The damage observed on the grip was preventing the hub to sit straight; which gave the expose needle the appearance of being bent.Root cause is determined to be related to a manufacturing issue.The plug probe and the load barrel stations in zone 5 have the ability to become misaligned and produce the type of damage observed in the returned sample.When there is a misalignment, the probe inadvertently contacts the edge of the grip and causes the damage observed in the complaint a formal corrective action will not be initiated at this time.Customer complaint trends are evaluated on a monthly basis.If the trend of a specific type of complaint warrants a formal corrective action, resources will be assigned at that time.
