Cardiac electrode device having at least a portion thereof which is ribbon shaped
First Claim
1. An electrode device for in vivo delivery of electrical signals to and reception of electrical signals from cardiac tissue in a heart having a heart wall, said electrode device comprising:
- at least one elongate electrical conductor;
a flexible electrode cable having an outer coating of electrical insulation and containing said at least one elongate conductor, said flexible electrode cable having at least a portion which is ribbon-shaped;
an electrode, having a substantially flat exposed electrode surface, carried on said electrode cable and electrically connected to said elongate conductor, said portion of said cable which is ribbon-shaped forming means for endocardially retaining said exposed electrode surface in substantially flat contact with said heart wall; and
means for endocardially affixing said electrode cable to said heart wall.

Abstract
An electrode device, for intracardiac stimulation and/or defibrillation of heart tissue and/or sensing heart signals in a patient, has a soft, flexible electrode cable with an outer coating of insulation containing at least one elongate conductor connected to an electrode arranged on the electrode cable. In order to attain an electrode device of this kind which is structurally very simple and in which all the electrodes on the electrode cable can be applied to the heart wall in a very simple manner so the entire electrode surface faces the wall and firmly presses against it, the electrode cable is at least partially ribbon-shaped.
