Patent ID: 7539545

Claim:
An electromagnetic interference immune implantable medical device, comprising: a selectively conductive structure; said selectively conductive structure including: a first electromagnetic insulating layer; a first layer, formed on said first electromagnetic insulating layer, said first layer having a plurality of first conductive rings each having a first width and length and being composed of first conductive material, each first conductive ring being separated by a first insulating material, a second electromagnetic insulating layer having said first length and a second narrower width than said first width; a second electromagnetic insulating layer formed on said first layer; a second layer, formed on said second electromagnetic insulating layer, said second layer having a plurality of second conductive rings forming a continuous spiraling coil of loops, each loop having said first width and length, said plurality of second conductive rings being composed of second conductive material, and wherein each loop of said continuous spiraling coil of loops is separated by a second insulating material having said first length and said second narrower width; and a third electromagnetic insulating later formed on said second layer; wherein said plurality of first conductive rings are regularly spaced with respect to said first insulating material, and wherein said continuous spiraling coil of loops formed by said plurality of second conductive rings is positioned such that each loop of said continuous spiraling coil of loops overlaps a portion of a conductive ring of said first conductive rings and overlaps a portion of an adjacent conductive ring of said first conductive rings; and wherein at least one of said first, second, and third electromagnetically insulating layers comprises a self-heating dielectric material.
