It was reported that a patient's generator could not be interrogated.It appears that 3 different programmers were unsuccessful at interrogating (provider's, another provider's, and the or tablet).The provider's tablet has been able to interrogated other generators since then.Replacing the wand batteries was attempted.X-rays were performed but no obvious issues were identified.The x-rays have not been reviewed by the manufacturer to date.Device history record for the generator was reviewed and the generator passed all quality control measures prior to distribution.Tablet data was reviewed.The data was only available from on date approximately 8 months prior to the failure to program.There were no anomalies in the data.A review of the longevity tables estimates between 6.4 and 10 years from beginning of life until intensified follow up (ifi) = yes; the generator has been implanted for approximately 3.75 years.It is not expected that the generator battery is depleted.No additional relevant information has been received to date.
