Other, other text: one used sample was returned for evaluation.Examination showed the device's metal needle was retracted past the needle base.The needle arm was pulled past the capture point.During production, the gripper safety needles are sampled for functional testing (hinge activation testing) to verify the parts are free of damage and workmanship defects and the manufacturing procedures are being followed.The device instructions for use document was reviewed and the following relevant warning was identified: "failure to use safety arm correctly (lift safety arm straight back to the lock position until it clicks) while removing needle from portal site could result in the needle tip re-emerging from the base, resulting in accidental needlestick with contaminated needle." the investigator took 2 samples from production and used the safety arm incorrectly (applied excessive force during withdrawal of the metal needle).The testing was able to induce the condition seen in the returned sample; the metal needle went past the safety point and was left exposed.The investigation determined the most likely cause of the issue was damage during use.
