Abstract
Abstract An electrode system includes a nonconductive material and straps for positioning and holding the nonconductive material against a body part. Flexible conductive fabric patches are attached to the nonconductive material along with lead wires for electrically connecting the fabric patches to a remote monitor or pulse generator. An electrically conductive adhesive gel pad is provided for releasably coupling the flexible conductive fabric patch to the body part. The pad is selectively removable from the fabric patch, enabling removal of the patch from the gel pad while the latter remains adhered to a body part. This facilitates release of the conductive fabric patch and separate disposal of the adhesive gel pad.
