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.
