Patent ID: 7555350

Claim:
A method of constructing an electromagnetic interference immune pacing/defibrillation lead, comprising: (a) providing a pacing/defibrillation lead; (b) wrapping a first tape, spirally, around the pacing/defibrillation lead, the first tape being composed of a first insulating substrate with conductive strips each having a first width and length formed thereon leaving non-conductive strips having said first length and a second width being narrower than said first width, the first tape being wrapped such that the first insulating substrate is adjacent the pacing/defibrillation lead, the conductive strips being formed at an angle on the first insulating substrate such that upon wrapping the conductive strips form a continuous spiral of 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 having said first width and length formed thereon leaving non-conductive strips having said first length and a second width being narrower than said first width, 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 a continuous spiral of conductive rings that conduct circumferentially; wherein each conductive ring of the third tape overlaps a portion of a first conductive ring of the first tape and overlaps a portion of a second conductive ring of the first tape, the second conductive ring of the first tape being adjacent to the first conductive ring of the first tape.
