Abstract

Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including transcatheter medical treatments and/or for treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. The systems, apparatuses, and methods disclosed herein may include applying one or more heart splints to the patient's heart to apply pressure to the heart to reshape the heart. Anchors disclosed herein may be utilized in plugs for treating openings in a septum between two chambers of a heart, e.g., ventricular septal defects (VSD), atrial septal defects (ASD), and patent foramen ovale (PFO). In addition, the anchors disclosed herein may be utilized to reshape an annulus of a patient's heart valve, including a tricuspid valve of a patient's heart. The anchors disclosed herein may also be utilized to reposition a heart valve leaflet to reduce heart valve leaflet prolapse.

First claim

What is claimed is:

1. A heart anchor comprising:
a ring having two ends and configured to move from a linearized configuration to a ring-shaped configuration, the ring in the ring-shaped configuration having a thickness in an axial dimension and having a width in a radial dimension and having a length, the ring having a top surface and a bottom surface facing opposite the top surface in the axial dimension, the top surface and the bottom surface extending along an entirety of the length of the ring, and a first portion of the ring overlapping a second portion of the ring in the axial dimension in the ring-shaped configuration to form an overlapping portion at which the top surface faces towards the bottom surface, and the ring including a non-overlapping portion at which portions of the ring do not overlap, the thickness of the ring at the overlapping portion being at least double the thickness of the ring at the non-overlapping portion, and wherein the bottom surface and the top surface are each planar along the entirety of the length of the ring and each surface is placed respectively and entirely within its own plane in the linearized configuration and in the ring-shaped configuration; and
a cover coupled to the ring and extending inward from the ring in the ring-shaped configuration.

2. The heart anchor of claim 1 , wherein the two ends of the ring include a first end and a second end, and the first portion of the ring includes the first end of the ring.

3. The heart anchor of claim 1 , wherein the first portion of the ring does not overlap the second portion of the ring in the linearized configuration.

4. The heart anchor of claim 1 , wherein the ring is configured to automatically move from the linearized configuration to the ring-shaped configuration.

5. The heart anchor of claim 4 , wherein the ring is made of a shape-memory material.

6. The heart anchor of claim 1 , wherein the cover includes at least one cut-out portion.

7. The heart anchor of claim 1 , wherein the cover includes a central portion and a peripheral portion when the ring is in the ring-shaped configuration.

8. The heart anchor of claim 7 , wherein the cover includes overlapping material extending from the peripheral portion to the central portion.

9. The heart anchor of claim 8 , wherein the overlapping material includes a first layer and a second layer, the first layer including a pattern of cut-outs and the second layer including a pattern of cut-outs having a different shape than the pattern of cut-outs of the first layer.

10. The heart anchor of claim 7 , wherein the central portion includes a coupler for coupling to a tension member and the peripheral portion includes a coupler for coupling to the ring.

11. The heart anchor of claim 1 , wherein the cover is configured to be puncturable by a puncture device.

12. The heart anchor of claim 11 , wherein the cover includes a knitted material having openings for the puncture device to pass through.

13. The heart anchor of claim 1 , further comprising a mesh layer coupled to the cover.

14. The heart anchor of claim 1 , wherein the two ends of the ring include a first end and a second end, and the first portion of the ring is configured to overlap the second portion of the ring such that the first end is offset along the length of the ring from the second end.

15. The heart anchor of claim 1 , wherein the first portion of the ring is configured to overlap the second portion of the ring to at least 10 degrees of the ring.

16. The heart anchor of claim 1 , wherein the first portion of the ring is configured to overlap the second portion of the ring to at least 20 degrees of the ring.

17. The heart anchor of claim 1 , wherein the first portion of the ring overlapping the second portion of the ring comprises a single overlap.

18. The heart anchor of claim 1 , wherein edges of the first portion and the second portion are aligned with each other in the radial dimension at the overlapping portion.

19. The heart anchor of claim 1 , wherein a thickness of the ring between the top surface and the bottom surface in the axial dimension is uniform along the entirety of the length of the ring in the linearized configuration and in the ring-shaped configuration.

20. The heart anchor of claim 2 , wherein the ring is unitary from the first end to the second end.
