Abstract

A wearable therapeutic device that includes a garment configured to contain an external defibrillator. The garment is configured to house at least one of an alarm module and a monitor and to house a first therapy electrode and a second therapy electrode. The garment is also configured to releasably receive a receptacle that contains a conductive fluid proximate to at least one of the first therapy electrode and the second therapy electrode, and to electrically couple the receptacle with the garment.

Claims

1. An electrode system comprising:

a garment configured to be worn by a patient;

a first electrode configured to deliver a therapeutic shock to the patient;

a second electrode configured to contact the patient; and

an attachment mechanism to cause the second electrode to snap into the garment.

2. The electrode system of claim 1, wherein the second electrode comprises a sensing electrode for monitoring a parameter associated with the patient.

3. The electrode system of claim 1, wherein the attachment mechanism comprises a first part of a snap disposed on the second electrode and configured to releasably engage with a second part of the snap, the second part disposed on the garment.

4. The electrode system of claim 1, wherein the attachment mechanism is formed of a conductive material.

5. The electrode system of claim 1, wherein the garment comprises a shirt formed of a breathable fabric.

6. The electrode system of claim 1, further comprising a defibrillator disposed in the garment and electrically coupled to the first electrode.

7. The electrode system of claim 1, further comprising a processor to cause transmission of a patient notification informing the patient to respond to the notification.

8. The electrode system of claim 1, further comprising a processor to cause communication of a warning of the therapeutic shock to the patient, the warning being at least one of an audible warning, a visual warning, and a haptic warning.

9. The electrode system of claim 1, further comprising a user interface control, and a processor in communication with the user interface control, the processor to allow the patient to prevent delivery of the therapeutic shock.

10. The electrode system of claim 1, wherein a therapy electrode assembly comprises the first electrode, the system further comprising a pocket formed in the garment and including a feature facilitating insertion of the therapy electrode assembly into the pocket in a correct orientation.

11. The electrode system of claim 10, wherein the feature comprises magnets configured to guide an alignment of the therapy electrode assembly within the pocket.

12. The electrode system of claim 1, further comprising an alignment mechanism for aligning the second electrode in a predetermined manner with the garment.

13. The electrode system of claim 1, wherein at least the first electrode is configured to be disposed in a pocket of the garment.

14. The electrode system of claim 1, wherein the first electrode is formed of an electrically conductive material, the electrically conductive material being an integral part of the garment.

15. An electrode system comprising:

a fabric garment wearable on a torso of a patient;

a first electrode formed from an electrically conductive material, the first electrode disposed within the garment;

a second electrode including a first part of a snap configured to engage a second part of the snap, the second part disposed on the garment;

a defibrillator disposed within the garment and electrically coupled to the first electrode; and

a processor to cause the second electrode to sense a cardiac condition of the patient.

16. The electrode system of claim 15, further comprising a plurality of therapy electrodes formed from the electrically conductive material.

17. The electrode system of claim 15, wherein the defibrillator is configured to deliver a biphasic defibrillation shock based on sensing the cardiac condition of the patient.

18. The electrode system of claim 15, wherein the processor is configured to cause a user interface control to communicate an impending shock to the patient.

19. The electrode system of claim 18, wherein the processor can cause the user interface control to allow the patient to override delivery of the impending shock.

20. The electrode system of claim 19, wherein the user interface control includes at least one button.

21. The therapy electrode system of claim 15, wherein the garment comprises one of a vest and a shirt.
