The valve was returned for evaluation: device history record (dhr) - lot clccl2 conformed to the specifications when released to stock.Failure analysis - the valve was visually inspected; needle holes in the silicone housing were noted, and the unitized catheter was cut/torn.The position of the cam when valve was received was 200mmh2o.The valve was hydrated.The valve was leak tested and only leaked from the needle holes.The valve passed the test for programming, occlusion, reflux, siphon guard and pressure.No root cause could be determined as the technician could not confirm any problem with the valve at the time of investigation.The root cause for the cut/tear in the unitized catheter was probably due to a sharp or pointed object coming into contact with the catheter as noted in the ifu silicone has a low cut/tear resistance.The possible root cause for the deviation of the abdominal catheter was probably the increase in height of the patient and the occurrence of gravitational force as reported by the customer.
