Investigation results: received one unit of a 20gx1.25in nexiva device from an unknown lot number for the investigation of this complaint.A gross visual inspection shows that only few components of the unit were returned; a v-clip that has been separated from the unit and a needle protruding from the grip and held by the washer, which was positioned within the tip shield.The catheter assembly was decoupled and not returned.The safety shield was not engaged, and the needle was exposed.Per the customer¿s investigation, the safety shield of the needle broke upon removing the unit from the patient¿s arm.There were no other physical damages on the unit.Investigation was conducted by inspecting both the tip shield and the v-clip under the microscope.No physical damage was observed on either of the returned components.During manufacturing the v-clip may be mounted incorrectly due to machine misalignment.As the v-clip is seated into the tip shield any misalignment may cause the groove to not catch correctly.Therefore, during decoupling of the unit, the v-clip may fall as the only thing holding it is the engaged needle.Investigation conclusion(s): the defect of ¿shield defective¿ was confirmed.Probable root cause(s): manufacturing.A notification of awareness has been sent to the manufacturing department.
