The ventricular catheter (id 823041) was returned for evaluation.Failure analysis - the proximal connector of the valve and the catheter were visually inspected, marks in the proximal connector were noted, no other defects were noted, no defects were noted with the ends of the catheter, no suture tie marks were noted around the catheter.Disconnection was probably due to catheter not being tied to valve.The root cause for the issue reported by the customer is probably due to the catheter not being sutured to the connector.The root cause for the marks in the proximal connector noted during the investigation are due to a sharp / pointed object or unshod forceps coming into contact with the connector.
