Patent ID: 8082042

Claim:
An electrode device for cardiological or neurological electrodiagnosis and/or electrotherapy, comprising: an electrode body ( 12 ) that is elongated; at least one electrode ( 14 , 16 ) in the vicinity of a distal end ( 24 ) of said electrode body ( 12 ); an electrode conductor ( 44 ) for electrical connection of said at least one electrode ( 14 , 16 ) wherein said electrode conductor ( 44 ) comprises a fibrous structure ( 52 ) with anisotropic conductivity wherein a specific conductivity of said electrode conductor ( 44 ) is significantly higher in a longitudinal direction along said electrode conductor than in a transverse direction across said electrode conductor; wherein said fibrous structure ( 52 ) comprises individual fibers ( 54 ) comprising a fiber material wherein said individual fibers ( 54 ) comprise a plastic, conducting plastic or semiconductor material and wherein said individual fibers ( 54 ) have an insulating surface layer ( 56 ) that comprises a high resistance and wherein said insulating surface layer comprises said fiber material; wherein said insulating surface layer further comprises high resistance residues of said fiber material, or an oxidized portion of said fiber material; wherein said fibrous structure comprises a solid fiber composite or a bundle said individual fibers ( 54 ); and, wherein said bundle has centrally highly conducting fibers ( 58 ) which are surrounded by less highly conducting fibers ( 60 ), wherein longitudinal conductivity of said highly conducting fibers ( 60 ) gradually decreases radially.
