Abstract
A medical electrode lead employing one or more elongated electrode coils embedded in the surface of a flexible base pad. The electrode coils take the form of space wound coils following tortuous paths over the surface of the base pad to provide a large surface area electrode. The electrode coils include a plurality of spaced, generally parallel electrode coil segments. Located intermediate adjacent the parallel electrode coil segments are grooves or pleats, molded into the base pad. These grooves or pleats provide increased elasticity of the electrode and increased ability to conform to the contours of the heart. Insulative cores taking the form of plastic tubes are located within the electrode coils to prevent tissue ingrowth between the individual electrode coils, without induly reducing flexibility of the electrode.
