Implantable shielded medical device
First Claim
1. An implantable device comprised of a power source, means for generating electrical signals, means for communicating said electrical signals with biological matter in a biological organism, and a conductor assembly electrically connected to said biological matter, wherein:
- (a) said conductor assembly is comprised of a conductor that is capable of being flexed at least about 15 degrees and that has a resistivity at 20 degrees Centigrade of from about 1 to about 100 micro ohm-centimeters,(b) said conductor assembly is comprised of a magnetic shield disposed above said flexible conductor, wherein said magnetic shield is comprised of an antithrombogenic composition, wherein said magnetic shield is comprised of a layer of magnetic shielding material, and wherein said layer of magnetic shielding material, when exposed to a magnetic field with an intensity of at least about 0.5 Teslas, has a magnetic shielding factor of at least about 0.5; and
(c) said conductor assembly has a heat shielding factor of at least about 0.2 when tested in accordance with A.S.T.M. standard test Standard Test F-2182-02.

Abstract
An implantable device that contains a power source, a device for producing electrical signals, and a conductor assembly for communicating the electrical signals to biological matter. The conductor assembly contains of a conductor that is capable of being flexed at least about 15 degrees and that has a resistivity at 20 degrees Centigrade of from about 1 to about 100 micro ohm-centimeters. The conductor assembly also contains a magnetic shield located above the flexible conductor; the magnetic shield contains an antithrombogenic composition. The magnetic shield also contains a magnetic shielding material that has a magnetic shielding factor of at least about 0.5.
