Patent ID: 7529591

Claim:
An electromagnetic interference immune defibrillation lead, comprising: 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 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 a 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 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.
