Implantable medical device
First Claim
1. A method of manufacturing an implantable medical device having reduced MRI image distortion comprising:
- producing an implantable medical device, wherein the implantable medical device has a configuration that comprises a housing and one or more internal components disposed within the housing;
wherein the configuration is based upon a design process that includes;
creating a first prototype;
determining an 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, wherein said modifying results in a modified design that is the configuration for the implantable medical device.

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.
