Abstract

A multi-vector patient contact interface and method of use are disclosed.

Claims

1. A multi-vector patient contact interface, comprising:

two or more non-conductive substrates;

one or more electrical leads;

two or more conductive patient contacts wherein at least one patient contact is formed on each non-conductive substrate;

wherein each electrical lead is configured to be electrically connected to at least one of the two or more patient contacts; and

wherein the two or more patient contacts are arranged in a configuration with at least one patient contact on each non-conductive substrate and each patient contact is electrically isolated from the other patient contacts by the non-conductive substrate.

2. The interface of claim 1, wherein each non-conductive substrate is flexible and capable of providing optimal contact with an uneven contact surface when the patient contact interface is placed against the uneven contact surface.

3. The interface of claim 2, wherein the contact surface is a contact surface of the body of a patient that is one or more of a torso of the patient, an abdomen of the patient, a limb of the patient and a head of the patient.

4. The interface of claim 1, wherein each conductive patient contact has a particular shape.

5. The interface of claim 1, wherein each conductive patient contact has a variety of shapes.

6. The interface of claim 1, wherein the two or more conductive patient contacts have one or more different sizes.

7. The interface of claim 1, wherein each conductive patient contact is adhesive.

8. The interface of claim 1, wherein the areas of non-conductive substrate in between the conductive patient contacts are adhesive.

9. The interface of claim 1, wherein one or more conductive patient contacts is a sensor.

10. The interface of claim 8, wherein the sensor is one of an active in nature sensor and a passive in nature sensor.

11. The interface of claim 1, wherein each conductive patient contact is an electrode.

12. The interface of claim 1, wherein the two or more patient contacts are one or more sensors and one or more electrodes.

13. The interface of claim 12, wherein the one or more sensors are arranged in the configuration separately from the one or more electrodes.

14. The interface of claim 12, wherein the one or more sensors are arranged in the configuration intermixed with the one or more electrodes.

15. The interface of claim 1, wherein the two or more conductive patient contacts are each connected to separate individual electrical leads.

16. The interface of claim 1, wherein two or more of the conductive patient contacts are connected to the same electrical lead.

17. The interface of claim 1 further comprising a generator that generates a multiphasic pulse and wherein each phase of the multiphasic pulse is delivered within its own unique segment of the overall pulse timing sequence.

18. The interface of claim 1 further comprising a generator that generates a multiphasic pulse and wherein one or more phases of the multiphasic pulse is delivered within a time segment that overlaps to a greater or lesser degree with one or more of the other timing segments in the overall pulse sequence.

19. A method for attaching a multi-vector patient contact interface to a patient, the method comprising:

providing one or more multi-vector patient contact interfaces wherein the one or more multi-vector patient contact interfaces are arranged in a configuration to provide optimal contact with a patient despite an uneven contact surface;

placing the multi-vector patient contact interface on a body of a patient.

20. The method of claim 19, wherein placing the multi-vector patient contact interface further comprises placing one or more multi-vector patient contact interfaces at a location on the body of the patient.

21. The method of claim 20, wherein the location on the body of the patient is at least one of a torso of the patient, a limb of the patient and a head of the patient.

22. The method of claim 19 further comprising delivering, using the multi-vector patient contact interface, a treatment to the patient.

29. The method of claim 22, wherein the pulse waveform is a multiphasic pulse waveform and each phase of the multiphasic pulse is delivered within its own unique segment of the overall pulse timing sequence.

30. The method of claim 22, wherein the pulse waveform is a multiphasic pulse waveform and one or more phases of the multiphasic pulse is delivered within a time segment that overlaps to a greater or lesser degree with one or more of the other timing segments in the overall pulse sequence.

23. A method for delivering a multi-vector pulse waveform to a patient, the method comprising:

providing the one or more multi-vector patient contact interfaces attached to a patient;

connecting a medical device capable of generating a pulse waveform to the electrical leads connected to the one or more multi-vector patient contact interfaces; and

delivering the pulse waveform from the medical device to the patient via the one or more multi-vector patient contact interfaces.

24. The method of claim 23, wherein the pulse waveform is delivered through the one or more multi-vector patient contact interfaces via one or more specific shock vectors and these shock vectors are selected either statically or dynamically by one or more of the operator, the manufacturer or an algorithm within the programming of the medical device.

25. The method of claim 24, wherein the one or more shock vectors selected are of at least a one-electrode-to-one-electrode, a one-electrode-to-many-electrode, a many-electrode-to-one-electrode, and a many-electrode-to-many-electrode configuration.

26. The method of claim 25, wherein the pulse waveform is a multiphasic pulse waveform and the one or more phases of a multiphasic pulse waveform are each routed via the same selected shock vector.

27. The method of claim 25, wherein pulse waveform is a multiphasic pulse waveform and the the one or more phases of a multiphasic pulse waveform are each routed via different selected shock vectors.

28. The method of claim 25, wherein the pulse waveform is a multiphasic pulse waveform and the one or more phases of a multiphasic pulse waveform are each routed via a combination of the same selected shock vector and different selected shock vectors.
