Abstract

A heart treatment device includes an annuloplasty ring for restoring function to a mitral valve, an occluder configured and arranged for implantation within a left atrial appendage and a connector interconnecting the annuloplasty ring and the occluder.

Claims

1. A heart treatment device having a first end and a second end opposite the first end, the first and second ends defining a maximum length of the heart treatment device in a collapsed condition in which the heart treatment device is receivable within a delivery device, the heart treatment device comprising:

an annuloplasty ring for a mitral valve being D-shaped and positioned at the first end of the heart treatment device;

an occluder having at least one body and a frame disposed within the at least one body, the occluder being configured and arranged for implantation within a left atrial appendage and positioned at the second end of the heart treatment device; and

a single connector extending laterally away from an external surface of the annuloplasty ring toward the left atrial appendage and interconnecting the annuloplasty ring and the occluder, the connector being attached at a first position on the annuloplasty ring, the single connector being the only connector interconnecting the annuloplasty ring and the occluder.

2. The heart treatment device of claim 1, wherein the at least one body includes a first body and a second body, the first body having a larger cross-section than the second body.

3. The heart treatment device of claim 1, wherein the frame is expandable and includes a plurality of radially-expandable ribs.

4. The heart treatment device of claim 1, wherein the at least one body comprises a mushroom-shaped body.

5. The heart treatment device of claim 1, wherein the connector comprises nitinol.

6. The heart treatment device of claim 1, wherein the occluder comprises a shape-memory material that is self-expandable from the collapsed condition during delivery into a patient to a relaxed condition during use in the patient.

7. The heart treatment device of claim 6, wherein the occluder comprises braided strands.

8. The heart treatment device of claim 6, wherein the shape-memory material is nitinol.

9. The heart treatment device of claim 1, wherein, the single connector being connected at only two positions including the first position on the annuloplasty ring, and second position on the at least one body.

10. The heart treatment device of claim 1, wherein the at least one body and the frame are formed of different materials.

11. A heart treatment device having a first end and a second end opposite the first end, the first and second ends defining a maximum length of the heart treatment device in a collapsed condition in which the heart treatment device is receivable within a delivery device, comprising:

an annuloplasty ring for a mitral valve being saddle-shaped and positioned at the first end of the heart treatment device;

an occluder having at least one body and a frame disposed within the at least one body, the occluder being configured and arranged for implantation within a left atrial appendage and positioned at the second end of the heart treatment device; and

a single connector extending laterally away from an external surface of the annuloplasty ring toward the left atrial appendage and interconnecting the annuloplasty ring and the occluder, the connector being attached at a first position on the annuloplasty ring, the single connector being the only connector interconnecting the annuloplasty ring and the occluder.
