Abstract
Abstract A disposable electrode includes a fabric backing and a conductive mesh layer laminated thereto. A conductive polymer adhesive interfaces the conductive mesh with the skin of the patient. In order to promote uniform current density, connection to external apparatus occurs by means of a stranded wire which meets the mesh at a point and extends laterally therefrom along the electrode, intermediate the mesh and the adhesive.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
162 words
A transcutaneous electrode providing electrical contact with a patient's skin, having substantial uniformity of current density and resistance to physical deformation comprising: (a) a conductive member having upper and lower surfaces and generally defining the configuration of said electrode; (b) an electrically conductive adhesive material, electrically and physically connected to and covering the lower surface of said conductive member, for interfacing said conductive member with the patient'skin; (c) electrical connection means for physically and electrically coupling said conductive member with an external electrical apparatus, said connection means including an electrical conductor joining said conductive member at a contact point along a side of said conductive member, thence extending away from said point substantially across the lower surface of said conductive member, said electrical conductor being in electrically conductive relation with said conductive member substantially across said lower surface; and (d) an electrically insulating tape reinforcing means overlaying the full length of said electrical conductor and simultaneously being bonded to said lower surface.
Claim 2
Dependent Claim
162 words
