Abstract
A medical electrode system includes an electrically non-conductive backing material and a flexible, electrically conductive patch disposed on the backing material. An electrically non-conductive facing material is disposed over the patch which includes an aperture therein for exposing a portion of the patch, said aperture having a maximum dimension smaller than a minimum dimension of the patch. A lead wire electrically connected to the patch, and a separate electrically conductive gel pad is provided for releasably coupling the patch to a body part, the gel pad having a minimum dimension larger than the aperture'"'"'s maximum dimension and formed from a material enabling the gel means to be removed, intact, from said body part and patch. The gel pad may further include a drug suitable for iontophoretic delivery. A strap system enables the patches and backing material to be applied in a compressing manner on a body part and in one embodiment, the entire system is both stretchable and flexible.
