Abstract

In one example, the present invention is directed to a wound-healing patch including a flexible substrate, at least one wound electrode and at least one return electrode. In the invention, the wound electrode(s) is positioned on a portion of the flexible substrate designed to be placed over wounded tissue and the return electrode is positioned on a portion of the substrate remote from the wound-healing electrode and designed to be placed over healthy tissue.

Claims

1. A wound-healing patch comprising:

a flexible substrate;

at least one wound electrode positioned on a portion of said flexible substrate adapted to be placed over wounded tissue; and

at least one return electrode positioned on said substrate remote from said wound-healing electrode, wherein said return electrode is positioned on a portion of said substrate adapted to be placed over healthy tissue.

2. A wound-healing patch according to claim 1 further comprising a voltage source connected between at least one of said wound electrodes and at least one of said return electrodes.

3. A wound-healing patch according to claim 1 further comprising a current source connected between at least one of said at least one wound electrode and at least one of said at least one return electrodes.

4. A wound-healing patch according to claim 1 further comprising at least one resistor connected to at least one of said at least one wound electrode.

5. A wound-healing patch according to claim 1 further comprising control electronics adapted to control the flow of current through said at least one wound electrode and said at least one return electrode.

6. A wound-healing patch according to claim 1 wherein one of said at least one wound-healing electrode or said at least one return electrode is electrically isolated from tissue when said patch is attached to said tissue.

7. A wound-healing patch according to claim 1 wherein both said at least one wound-healing electrode and said at least one return electrode are electrically isolated from tissue when said wound-healing patch is attached to tissue.

8. A wound-healing patch according to claim 7 wherein at least one said wound electrode or said at least one return electrode are isolated from said tissue by a distributed resistive element.

9. A wound-healing patch according to claim 1 wherein the collective area of said at least one return electrode is substantially larger than the collective area of said at least one wound electrode.

10. A wound-healing patch according to claim 1 wherein the collective area of said at least one return electrode is substantially smaller than the collective area of said at least one wound electrode.
