<p>A flexible, planar patch electrode (10) for cardiac defibrillation is fabricated from conductive wire mesh (12) covered on an insulation side by a flexible layer of insulation (14). The electrode (10) provides a substantial electrical contact area of 2-4 square inches and is shaped to provide an essentially rectangular base region (20) with a plurality of protrusions (22, 24) extending longitudinally therefrom. The protrusions (22, 24) may be readily flexed to follow natural heart contours and slots (26) between protrusions (22, 24) may be positioned to avoid features such as arteries near the surface of the heart. Central attachment of a lead within the base region minimizes current density and corresponding I<2>R energy losses. <IMAGE></p> |
