Abstract

An electrode assembly includes a first surface to be placed adjacent a person'"'"'s skin and a second surface including a plurality of reservoirs of conductive gel. The plurality of reservoirs of conductive gel are disposed on sections of the electrode assembly that are at least partially physically separated and may move at least partially independently of one another to conform to contours of a body of a patient. The electrode assembly is configured to dispense an amount of the electrically conductive gel onto the first surface in response to an activation signal and to provide for a defibrillating shock to be applied to the patient through the amount of the electrically conductive gel.

Claims

1. A therapy electrode system comprising:

a garment wearable on a torso of a patient;

a pocket formed in the garment; and

a therapy electrode configured to be inserted into the pocket, at least one of the pocket and the therapy electrode including a feature discouraging insertion of the therapy electrode into the pocket in an incorrect orientation, wherein the feature comprises the pocket being tapered from a first pocket end to a second pocket end and the therapy electrode being tapered from a first therapy electrode end to a second therapy electrode end.

2. The therapy electrode system of claim 1, wherein the feature further comprises a shape of the pocket which conforms to a shape of the therapy electrode.

3. The therapy electrode system of claim 1, wherein both a first edge of the therapy electrode is tapered and a second edge of the therapy electrode, opposite the first edge, is tapered.

4. The therapy electrode system of claim 3, wherein the first edge of the therapy electrode is tapered to a different degree than the second edge of the therapy electrode.

5. The therapy electrode system of claim 1, wherein a first edge of the therapy electrode is tapered and a second edge of the therapy electrode, opposite the first edge, is not tapered.

6. The therapy electrode system of claim 1, wherein one edge of the therapy electrode includes a cut out portion.

7. The therapy electrode system of claim 1, wherein the feature further comprises a first magnet disposed on the therapy electrode and a second magnet disposed on the garment.

8. The therapy electrode system of claim 7, wherein the second magnet is disposed on material forming the pocket.

9. The therapy electrode system of claim 1, wherein the feature further comprises a fastener including a male side disposed on one of the therapy electrode and the garment and a female side disposed on the other one of the therapy electrode and the garment.

10. The therapy electrode system of claim 9, wherein the feature further comprises a first snap portion disposed on the therapy electrode and a second snap portion disposed on the garment.

11. The therapy electrode system of claim 9, wherein the feature further comprises hook and loop fasteners.

12. The therapy electrode system of claim 1, wherein the therapy electrode includes a pull tab configured to facilitate insertion and/or removal of the therapy electrode from the pocket.

13. A therapy electrode system comprising:

a garment wearable on a torso of a patient;

a pocket formed in the garment; and

a therapy electrode configured to be inserted into the pocket, the pocket tapered from a first pocket end to a second pocket end, the therapy electrode tapered from a first therapy electrode end to a second therapy electrode end, a taper of the pocket and a taper of the therapy electrode discouraging insertion of the therapy electrode into the pocket in an incorrect orientation.

14. The therapy electrode system of claim 13, further comprising

a closing mechanism including a first portion disposed on the therapy electrode and a second portion disposed on the garment, the closing mechanism discouraging insertion of the therapy electrode into the pocket in an incorrect orientation.

15. The therapy electrode system of claim 14, wherein the first portion includes a first magnet and the second portion includes a second magnet.

16. The therapy electrode system of claim 14, wherein the closing mechanism includes a male side of a fastener disposed on one of the therapy electrode and the garment and a female side of the fastener disposed on the other one of the therapy electrode and the garment.

17. The therapy electrode system of claim 14, wherein the closing mechanism includes a first snap portion disposed on the therapy electrode and a second snap portion disposed on the garment.

18. The therapy electrode system of claim 14, wherein the closing mechanism includes hook and loop fasteners.

19. A therapy electrode system comprising:

a garment wearable on a torso of a patient;

a pocket formed in the garment; and

a therapy electrode configured to be inserted into the pocket, at least one of the pocket and the therapy electrode including a feature discouraging insertion of the therapy electrode into the pocket in an incorrect orientation, wherein one edge of the therapy electrode includes a cut out portion.
