The hakim valve (id 823113) was returned for evaluation.Device history record (dhr) - the product code 82-3113 with lot 5775694 conformed to the specifications when released.Failure analysis - the valve was visually inspected; no defects were noted.The valve was hydrated.The valve was tested for programming, the valve failed the test.The silicone was cut just after the valve casing and the cam mechanism was gently moved.The valve was retested for programming, the valve failed the test.The valve was dismantled and was examined under microscope at appropriate magnification: bump mark was noted in the valve casing.The cam magnets were controlled and failed.The root cause for the issue reported by the customer is due to the valve receiving a hard knock and abnormal polarization of the cam magnets.The root cause for the bump marks in the valve casing noted during the investigation is due to the valve receiving a hard knock.The root cause for the abnormal polarization noted during the investigation, was probably caused by an exposition of a too strong magnetic field, as noted in the ifu, ¿any magnet may experience a degradation of magnetic field strength as a consequence of exposure to the significantly stronger magnet field induced in a mri procedure.
