Abstract An implantable therapy system consists of multiple medical devices. When evaluating reliability of a certain device, the contribution of the device reliability to therapy system reliability should be considered. The impacts of the device failures on patients are very important to be assessed. In this paper, we start with a brief description of an implantable medical therapy system – a Neuromodulation therapy system. Focus will be on Neuromodulation lead, which is one of the key devices in the therapy delivery system. A major failure mode of the lead is studied with material assessment. The resulting lead reliability behavior is further studied. Then the lead reliability is assessed at the therapy system level.
