Abstract: A method of manufacturing an implantable medical device having reduced MRI image distortion, includes producing an implantable medical device. The implantable medical device has a configuration that comprises a housing and one or more internal components disposed within the housing. The configuration is based upon a design process that includes creating a first prototype, determining the aggregate relative magnetic permeability of the first prototype, and modifying the design of the first prototype by at least one of (a) selecting and adding a diamagnetic shimming material to the first prototype or (b) repositioning one or more internal components of the first prototype. Modifying the design results in a modified design that is the configuration for the implantable medical device.

Abstract: An implantable medical device includes a housing formed of a first material and a first electronic component provided within the housing. The implantable medical device also includes a second material provided in contact with at least a portion of the housing. At least one of the housing and the first electronic component has a magnetic permeability in a magnetic field that differs from the magnetic permeability of water. The second material is provided in an amount effective to reduce MRI image distortion caused by the implantable medical device.
