Patent ID: 7529590

Claim:
An electromagnetic interference immune pacing/defibrillation lead, comprising: a pacing lead; a first electromagnetic insulating layer formed around said pacing lead; 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 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 continuous spiraling coil of loops each having said first width and length, said continuous spiraling coil of loops being composed of second conductive material, each loop being separated by second insulating material having said first length and said second narrower width; and a third electromagnetic insulating layer formed on said second layer; said continuous spiraling coil of loops being positioned such that a section of said 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.
