Abstract
Abstract A transcutaneous medical electrode includes a highly conductive grid, having a plurality of arrays of electrical conductors, for controlling current distribution of directed electrical pulses. Electrical connectors are provided for establishing electrical communication with the conductive grid for enabling selective electrification of the electrical conductors in each array. The conductive grid is supported by a moderately conductive sheet, or film, and a conductive adhesive is provided for removably coupling the sheet or film and the conductive grid to a user's body.
