Abstract

Described herein is a device configured to be implanted into a live human or animal. The device includes an electrically non-conductive frame; one or more electrical components disposed in the electrically non-conductive frame; and a self-supporting film. The self-supporting film forms a hermetical seal with the electrically non-conductive frame. The self-supporting film and the frame enclose the electrical components. The device is configured to be implanted into a live human or animal. Also described herein is a method of making a device configured to be implanted into a live human or animal. The method includes providing an electrically non-conductive frame comprising one or more feedthroughs, openings and a cavity; disposing electrical components within the cavity; optionally filling the cavity with a material to embed the electrical components in the material; and sealing the openings by applying a self-supporting film to the one or more openings.

Claims

1. A device, comprising:

an electrically non-conductive frame;

one or more electrical components disposed in the electrically non-conductive frame; and

a self-supporting film;

wherein the self-supporting film forms a hermetical seal with the electrically non-conductive frame,

wherein the self-supporting film and the frame enclose the electrical components, and

wherein the device is configured to be implanted into a live human or animal.

2. The device of claim 1, wherein the frame comprises one or more openings.

3. The device of claim 1, wherein the frame is ceramic, plastic or polymer composite.

4. The device of claim 1, wherein the frame comprises one or more feedthroughs, wherein the one or more feedthroughs are functional to accommodate signal pathways between the device and the live human or animal.

5. The device of claim 2, wherein the self-supporting film seals the one or more openings.

6. The device of claim 1, wherein the self-supporting film is water impermeable.

7. The device of claim 1, wherein exposed surfaces of the self-supporting film are bio-compatible.

8. The device of claim 1, wherein the self-supporting film is uniform in its composition or is a composite.

9. The device of claim 1, wherein the self-supporting film has a layered structure having two or more distinct layers.

10. The device of claim 1, wherein the self-supporting film comprises parylene C, silicone or a combination thereof.

11. The device of claim 1, wherein the self-supporting film comprises an adhesive layer.

12. The device of claim 1, wherein the self-supporting film is electrically non-conductive.

13. The device of claim 1, wherein the self-supporting film is flexible.

14. The device of claim 1, wherein the electrical components are configured to receive signals from a device outside the live human or animal, or transmit signals to a device outside the live human or animal, or both.

15. The device of claim 1, wherein the electrical components are embedded in a material.

16. The device of claim 15, wherein the material is thermally conductive.

17. The device of claim 4, wherein the device is entirely coated with a coating except the one or more feedthroughs.

18. The device of claim 17, wherein the coating is bio-compatible.

23. The device of claim 1, wherein the device comprises a surface with an area less than 2 cm².

24. The device of claim 1, wherein the device is injectable into the live human or animal through a syringe.

25. The device of claim 1, wherein the electrically non-conductive frame is free from an electrically conductive coating.

19. A method of making a device configured to be implanted into a live human or animal, comprising:

providing an electrically non-conductive frame comprising one or more feedthroughs, one or more openings and a cavity;

disposing one or more electrical components within the cavity;

sealing the one or more openings by applying a self-supporting film to the one or more openings.

20. The method of claim 19, wherein self-supporting film is applied layer by layer.

21. The method of claim 19, further comprising coating the device except the one or more feedthroughs.

22. The method of claim 19, further comprising filling the cavity with a material to embed the electrical components in the material.

26. A device, comprising:

a frame configured to provide mechanical support of the device;

one or more electrical components configured to provide therapy to a live human or animal, to receive power from a device external to the live human or animal, to transmit data to a device external to the live human or animal, to receive data to a device external to the live human or animal, or any combination thereof;

wherein the one or more electrical components are disposed in the frame; and

a self-supporting film configured to protect the one or more electrical components from tissues of the live human or animal;

wherein the device is configured to be implanted into the live human or animal.

27. The device of claim 26, wherein the self-supporting film and the frame enclose the one or more electrical components.

28. The device of claim 26, wherein the self-supporting film is water impermeable.

29. The device of claim 26, wherein exposed surfaces of the self-supporting film are bio-compatible.

30. The device of claim 26, wherein the self-supporting film is flexible.
