Filed:

Mar 30, 2012

Appl. No.:

13/435931

Inventors:

Timothy J. Claude - Coon Rapids MN,
Lois Claude - Coon Rapids MN,
Cherik T. Bulkes - Sussex WI,
Mary Kay Norby - Menomonee Falls WI,
Stephen T. Denker - Mequon WI,
Leonard J. Schultz - Holland PA,

International Classification:

H01F 27/02

US Classification:

336 90

Abstract:

An electrical lead body for an implantable electronic medical device has multiple layers of insulating material encapsulating a conductor that is wound in a spiral manner along the length of the lead. The layered structure provides resistance to fracture from mechanical stresses. A manufacturing process for producing this electrical lead is described.

Abstract:

A method of manufacturing an implantable electrical lead body MRI used in such applications as cardiac pacing, electrical nerve stimulation and intracardiac defibrillation applications that is biocompatible upon implantation in an animal and compatible with a magnetic resonance imaging scanner for the purpose of diagnostic quality imaging is disclosed. The method involves a relatively rigid first substrate layer, a conductive coil layer being precisely placed over the first substrate layer, a relatively soft second substrate layer over the conductive coil layer and a relatively rigid third substrate layer over the second substrate layer.
