Abstract
An electrosurgical return electrode is disclosed. The electrosurgical return electrode includes a conductive pad. The conductive pad includes a perimeter which has at least one involuted peripheral edge which is configured to reduce the current density of the conductive pad at the perimeter of the conductive pad. The involuted peripheral edge includes a depth and a width. The depth of the involuted edge is at least about 30% of the width of the involuted edge.
