Abstract

An electronic stimulator for delivery of energy to a treated body portion through a garment or other form of electrode, and a method of treatment using said stimulator. A connector strap comprising diode bridge circuitry maintains proper polarity on the electrodes regardless of the orientation of connection between the stimulator and the electrode.

Claims

1. A system for delivering energy to a treated body portion of a human or animal subject, comprising:

an electrode for application to the treated body portion; and

an electronic stimulator attached directly to the electrode, said electronic stimulator delivering energy to the electrode.

2. The system of claim 1, wherein the electrode is a garment electrode.

3. The system of claim 2, wherein the garment electrode comprises a glove.

4. The system of claim 2, wherein the garment electrode comprises a sock.

5. The system of claim 2, wherein the garment electrode comprises a sleeve.

6. The system of claim 2, wherein the garment electrode comprises at least two conductive portions, said conductive portions being separated from one another by a non-conductive portion.

7. The system of claim 2, wherein the garment electrode provides compression to the treated body portion.

8. The system of claim 7, wherein the garment electrode provides gradient compression to the treated body portion.

9. The system of claim 1, wherein the electronic stimulator comprises a curved inner face for placement against the electrode.

10. The system of claim 1, wherein the electronic stimulator has a height and a width of no more than about 2.5 inches.

11. The system of claim 1, wherein the electronic stimulator has a thickness of no more than about 0.65 inches.

12. The system of claim 1, wherein the electronic stimulator has a weight of no more than about 2.0 ounces.

13. The system of claim 1, wherein the electronic stimulator is attached to the electrode by a connector strap.

14. The system of claim 13, wherein the connector strap comprises a diode bridge for maintaining an intended polarity of the energy delivered to the electrode.

15. A therapeutic stimulator comprising an energy source, at least one electrical connection for delivering energy from said energy source to an electrode, and means for direct attachment of said stimulator to the electrode.

16. The therapeutic stimulator of claim 15, further comprising an outer housing having a curved inner face for placement against the electrode.

17. The therapeutic stimulator of claim 15, having a height and a width of no more than about 2.5 inches.

18. The therapeutic stimulator of claim 15, having a thickness of no more than about 0.65 inches.

19. The therapeutic stimulator of claim 15, having a weight of no more than about 2.0 ounces.

20. The therapeutic stimulator of claim 15, wherein said means for direct attachment of said stimulator to the electrode comprises a connector strap.

21. The therapeutic stimulator of claim 20, wherein the connector strap also provides the at least one electrical connection for delivering energy from said energy source to an electrode.

22. The therapeutic stimulator of claim 21, wherein the connector strap comprises a diode bridge for maintaining an intended polarity of the energy delivered to the electrode.

23. A connector strap for providing electrical connection between an electronic stimulator and a pair of electrodes, said connector strap comprising:

first and second inner contacts;

first and second outer contacts;

a first conductor path between said first inner contact and said first outer contact, said first conductor path comprising a first diode;

a second conductor path between said first inner contact and said second outer contact, said second conductor path comprising a second diode;

a third conductor path between said second inner contact and said first outer contact, said third conductor path comprising a third diode; and

a fourth conductor path between said second inner contact and said second outer contact, said fourth conductor path comprising a fourth diode.

24. The connector strap of claim 23, wherein the first and second inner contacts comprise snap connectors for connection to the electronic stimulator.

25. The connector strap of claim 23, wherein the first and second outer contacts comprise snap connectors for connection to the electrodes.

26. A method of treating a body portion of a human or animal subject, comprising:

applying a garment electrode to a body portion to be treated; and

delivering therapeutic energy to the electrode from an electronic stimulator attached directly to the electrode.

27. The method of claim 26, further comprising applying compression to the body portion to be treated.

28. The method of claim 27, wherein gradient compression is applied to the body portion to be treated.
