Abstract

A method and system for an improved wearable defibrillator specifically optimized for patient comfort and compliance. The system is capable of sensing information about the patient, determining whether the patient is experiencing a life-threatening arrhythmia, and if so, deliver life-saving defibrillation. The system is specifically designed, constructed, and configured to allow for minimal weight on the shoulders and its associated lumbar spine compression when standing and minimal pressure on the abdomen or thorax when supine in order to increase patient comfort and compliance. This configuration and design can be implemented in several forms including but not limited to the material(s) used, the placement of various components, the durability of the components, the operative or communicative connection between various components, the efficiency and/or accuracy of the various components in performing their functions, and/or the maintenance procedure.

Claims

3. The system of claim 2, wherein the electrical conductors are long-term adhesive electrodes.

4. The system of claim 1, wherein the sensing electrical conductors coupled to the skin are contained in a separate system subcutaneously implanted cardiac monitoring device, which is closely coupled to the wearable heart rhythm treatment device and communicates wirelessly heart rhythm related information from the subject.

5. The system of claim 1 in which the control system and remote monitoring system contained within the wearable heart rhythm treatment device can wirelessly and securely send and receive information to and/or from “

the cloud”

or other remote locations or sites regarding the wearable heart rhythm device'"'"'s performance, function, arrhythmia detection and treatment, alerts, and alarms, which information is then accessible via a world wide web connected computerize system.

6. The system of claim 5 in which the remote monitoring system utilizes a cellular service, wife service, and/or other wireless system to transmit and receive data.

7. The system of claim 1, wherein the treatment therapies includes both cardioversion and defibrillation therapies.

8. The system of claim 7, wherein the treatment therapies also includes pacing therapies.

9. The system of claim 1, wherein detecting abnormal heart rhythms is categorized into significant slow heart rhythms requiring pacing therapy and significant fast heart rhythms requiring cardioversion or defibrillation therapy.

10. The system of claim 1, wherein the user interface is a separately wearable device that wirelessly displays and communicates information from the wearable heart rhythm device to the subject in order to provide information regarding their status as well as that of their wearable heart rhythm device, any arrhythmias and/or shock warnings or alerts, as well as the ability to abort a shock.

11. The system of claim 10, wherein said user interface is a wrist worn device similar to a watch.

13. The system of claim 1, wherein part of the control system, sensing electrodes, and/or power supply are accessible and/or removable by the subject and the point of detachment/reattachment is designed to keep out water.

14. The system of claim 1, wherein one or more of the electrical conductors are made from a conductive textile material or woven into a breathable conductive fabric.
