One 14f x 28cm split cath was received for evaluation.A visual examination of the device reveals the red extension tubing is almost completely separated from the hub.Inside the hub, there is no evidence of extension material that would indicate the tubing tore.It appears the tubing pulled out of the hub.A supplier corrective action request was issued to the contract manufacturer for this event.The piece was evaluated dimensionally, visually, and cross sectionally.Visually there is no residue or damage in the affected area.Dimensionally the od and id of the extension are within specification.In the cross-section the lack of depth of the extension within the body of the catheter is observed.The device history record (dhr) review showed nothing out of specification, no authorized manufacture variance (amv), or non-conformance report (ncr) for the lot.Process review included the following operations- hub molding, leak test, and inspection.The investigation revealed the root cause is most likely failure to properly follow the procedures during the molding and inspection processes.As a result, the molding procedure was revised to include an audible alarm if the machine detects a rejection.All personnel involved in the molding and inspection processes were retrained to the procedures.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
