Abstract

An actuation system for assisting the operation of a natural heart that includes a dome structure configured for being coupled with a ventricular portion of the heart. The dome structure has at least one opening formed therein. The dome structure, proximate the opening, is configured to interface with at least one of an atrial chamber and a great vessel of the heart. A stabilizing element or an actuating element may be anchored to the dome structure for engaging a portion of the heart.

Claims

1. An actuation system for assisting the operation of a natural heart comprising:

a dome structure configured for being coupled with a ventricular portion of the heart, the dome structure having at least one opening formed therein;

the dome structure, proximate the opening, being configured to interface with at least one of an atrial chamber and a great vessel of the heart; and

one of a stabilizing element and an actuating element being anchored to the dome structure for engaging a portion of the heart.

2. The actuation system of claim 1 wherein the dome structure is formed of a flexible material.

3. The actuation system of claim 1 wherein the dome structure is formed of a generally rigid material.

4. The actuation system of claim 1 further comprising a locking structure positioned internally of at least one of the atria or great vessels, the dome structure configured for interfacing with the locking structure through a wall of one of the atria or great vessels

5. The actuation system of claim 1 further comprising a plurality of openings formed in the dome structure.

6. The actuation system of claim 1 further comprising:

a suture structure positioned internally of at least one of the atria and great vessels; and

sutures spanning a wall of one of the atria and great vessels and anchoring the dome structure with the suture structure.

7. The actuation system of claim 6 wherein the suture structure is an angioplasty ring.

8. The actuation system of claim 1 further comprising a cushion positioned between the dome structure and the heart.

9. A heart-mounted structure for assisting the operation of a natural heart comprising:

a dome structure configured for being coupled a basal surface of a ventricular portion of the heart, the dome structure having at least one opening formed therein; and

the dome structure, proximate the opening, being configured to interface with at least one of an atrial chamber and a great vessel of the heart.

10. The heart-mounted structure of claim 9 wherein the dome structure is formed of a flexible material.

11. The heart-mounted structure of claim 9 wherein the dome structure is formed of a generally rigid material.

12. The heart-mounted structure of claim 9 wherein the dome structure is configured for interfacing, through a wall of one of the atria or great vessels, with a locking structure positioned internally of at least one of the atria or great vessels.

13. The heart-mounted structure of claim 9 further comprising a plurality of openings formed in the dome structure.

14. The heart-mounted structure of claim 9 wherein the dome structure includes an extension section extending therefrom to interface with at least one of the atria and great vessels.

15. The heart-mounted structure of claim 9 further comprising a sleeve for interfacing with at least one of the atria and great vessels, the dome structure holding the sleeve in place when positioned on the heart.

16. The heart-mounted structure of claim 9 wherein the dome structure includes a textured surface for interfacing with a heart surface.

17. The heart-mounted structure of claim 9 further comprising a cushion for positioning between the dome structure and the heart.

18. The heart-mounted structure of claim 17 wherein the cushion is coextensive with the entire dome.

19. The heart-mounted structure of claim 17 wherein the cushion interfaces with an opening in the dome.

20. The heart-mounted structure of claim 17 wherein the cushion is integral with the dome.

21. The heart-mounted structure of claim 9 further comprising a ring structure positioned around the opening in the dome structure.

22. The heart-mounted structure of claim 9 wherein the dome structure includes separated sections for positioning the dome structure proximate the atria or great vessels.

23. The heart-mounted structure of claim 9 further comprising at least one of a stabilizing element and an actuating element, the dome structure configured for interfacing with such an element to anchor the element.

24. The heart-mounted structure of claim 23 wherein the one of a stabilizing element and actuating element are integrally formed with the dome structure.
