Electromagnetic interference immune pacing/defibrillation lead
First Claim
1. A method of constructing an electromagnetic interference immune pacing/defibrillation lead, comprising:
- (a) providing a pacing lead;
(b) wrapping a first tape, spirally, around the pacing lead, the first tape being composed of a first insulating substrate with conductive strips formed thereon, the first tape being wrapped such that the first insulating substrate is adjacent the pacing lead, the conductive strips being formed at an angle on the first insulating substrate such that upon wrapping the conductive strips form conductive rings that conduct circumferentially;
(c) wrapping a second tape, spirally, around the first tape, the second tape being composed of a second insulating substrate; and
(d) wrapping a third tape, spirally, around the second tape, the third tape being composed of a third insulating substrate with conductive strips formed thereon, the third tape being wrapped such that the conductive strips are adjacent the second tape, the conductive strips being formed at an angle on the third insulating substrate such that upon wrapping the conductive strips form conductive rings that conduct circumferentially.

Abstract
An electromagnetic interference immune defibrillator lead has a first electromagnetic insulating layer. A first layer is formed on the first electromagnetic insulating layer, the first layer having a plurality of first conductive rings composed of first conductive material, each first conductive ring being separated by first insulating material. A second electromagnetic insulating layer is formed on the first layer. A second layer is, formed on the second electromagnetic insulating layer, the second layer having a plurality of second conductive rings composed of second conductive material, each second conductive ring being separated by second insulating material. A third electromagnetic insulating layer is formed on the second layer. The second conductive rings of second conductive material are positioned such that a second conductive ring overlaps a portion of a first conductive ring and overlaps a portion of a second conductive ring, the second conductive ring being adjacent to the first conductive ring. The second electromagnetically insulating layer is composed of a self-healing dielectric material.
