BIOELECTRIC DEVICES AND METHODS OF USE
A composite, expandable, overlapping bioelectric device includes multiple first reservoirs and multiple second reservoirs joined with a planar substrate. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.
1 . A method of dressing a wound with at least two dressings, each dressing comprising an absorbent layer and a substrate layer comprising two or more biocompatible electrodes configured to generate at least one of;
a uniform low level electric field (LLEF); or
a uniform low level electric current (LLEC);
said method comprising the sequential, overlapping application of at least two dressings, wherein in at least one of the dressings, said substrate layer extends to the perimeter of said dressing.
2 . The method of claim 1 wherein the biocompatible electrodes comprise a first array comprising a pattern of microcells formed from a first conductive material, and a second array comprising a pattern of microcells formed from a second conductive material.
3 . The method of claim 2 wherein the first conductive material and the second conductive material comprise the same material.
4 . The method of claim 2 wherein the first and second array each comprise a discrete circuit.
5 . The method of claim 3 , further comprising a power source.
6 . The method of claim 4 wherein the first array and the second array spontaneously generate a LLEF.
7 . The method of claim 6 wherein the first array and the second array spontaneously generate a LLEC when contacted with an electrolytic solution or with a conductive fluid.
8 . The method of claim 6 wherein the LLEF is between 0.05 and 5 Volts.
