Abstract
Abstract An implantable system having internal circuitry configured to withstand a pre-determined amount of sterilization radiation is provided. In general, the system includes an internal control module in electrical communication with an implantable medical device. The internal control module can include a circuit board configured to withstand radiation and/or any number of integrated circuits (e.g., application specific integrated circuits) wherein the circuits or at least some portion thereof are fabricated so as to withstand some amount of radiation. For example, some portion of the circuitry can be fabricated utilizing radiation compliant material(s), silicon-on-insulator technology, and/or gallium arsenide technology. Additionally, the circuitry can include various components which are inherently resistant to such radiation (e.g., components fabricated utilizing magnetic field based technology, surface acoustical wave devices, etc.). A method of sterilizing an implantable medical device via radiation is also provided.
