Abstract

A method for delivering a prosthetic valve to a native annulus of a heart can include inserting a delivery apparatus into a patient's body, advancing the delivery apparatus to an implantation location within the native annulus, retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath, and after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve.

First claim

The invention claimed is:

1. A method for delivering a prosthetic valve to a native annulus of a heart, comprising:
inserting a delivery apparatus into a patient's body;
advancing the delivery apparatus to an implantation location within the native annulus;
retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath; and
after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve;
wherein reducing the axial tension on the first end of the prosthetic valve precedes reducing the axial tension on the second end of the prosthetic valve.

2. The method of claim 1 , wherein reducing the axial tension on the first end and the second end of the prosthetic valve comprises reducing the axial tension on a plurality of sutures of the delivery apparatus.

3. The method of claim 1 , wherein reducing the axial tension on the first end and the second end of the prosthetic valve comprises moving a first manifold of the delivery apparatus axially proximally toward a second manifold of the delivery apparatus.

4. A method for delivering a prosthetic valve to a native annulus of a heart, comprising:
inserting a delivery apparatus into a patient's body;
advancing the delivery apparatus to an implantation location within the native annulus;
retracting a delivery sheath of the delivery apparatus relative to the prosthetic valve to expose the prosthetic valve from a distal end of the delivery sheath; and
after the prosthetic valve is exposed from the delivery sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by reducing axial tension on a first end and a second end of the prosthetic valve;
wherein reducing the axial tension on the first end and the second end of the prosthetic valve comprises moving a first manifold of the delivery apparatus axially proximally toward a second manifold of the delivery apparatus, and
wherein the radially expanded state of the prosthetic valve is a first radially expanded state, and the method further comprises expanding the prosthetic valve from the first radially expanded state to a second radially expanded state by radially converging the first end and the second end of the prosthetic valve and axially compressing the first end and the second end of the prosthetic valve by moving the first manifold of the delivery apparatus axially proximally toward the second manifold of the delivery apparatus, wherein the prosthetic valve is radially larger in the second radially expanded state than in the first radially expanded state.

5. The method of claim 4 , wherein reducing the axial tension on the first end of the prosthetic valve and reducing the axial tension on the second end of the prosthetic valve occur simultaneously.

6. The method of claim 4 , further comprising radially compressing the prosthetic valve by moving the first manifold of the delivery apparatus axially distally away from the second manifold of the delivery apparatus.

7. A method for delivering a prosthetic valve to a native annulus of a heart, comprising:
inserting a sheath of a delivery apparatus into a patient's body, wherein a distal end portion of the prosthetic valve is releasably coupled to a first suture guide of the delivery apparatus via one or more first sutures, wherein a proximal end portion of the prosthetic valve is releasably coupled to a second suture guide of the delivery apparatus via one or more second sutures, and wherein the prosthetic valve, the first suture guide, and the second suture guide are disposed within the sheath;
advancing the sheath together with the prosthetic valve to an implantation location within the native annulus;
retracting the sheath to expose the prosthetic valve, the first suture guide, and the second suture guide from the sheath; and
after the prosthetic valve, the first suture guide, and the second suture guide are exposed from the sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by moving the first suture guide and the second suture guide toward each other;
wherein after moving the first suture guide and the second suture guide toward each other, the method further comprises reducing tension in the first sutures or the second sutures.

8. The method of claim 7 , wherein prior to moving the first suture guide and the second suture guide toward each other, the method further comprises reducing tension in the first sutures or the second sutures.

9. The method of claim 7 , wherein prior to moving the first suture guide and the second suture guide toward each other, the method further comprises reducing tension in the first sutures and the second sutures.

10. The method of claim 7 , wherein the first suture guide is coupled to a first shaft of the delivery apparatus, wherein the second suture guide is coupled to a second shaft of the delivery apparatus, and wherein the first shaft extends coaxially through the second shaft and the second suture guide.

11. A method for delivering a prosthetic valve to a native annulus of a heart, comprising:
inserting a sheath of a delivery apparatus into a patient's body, wherein a distal end portion of the prosthetic valve is releasably coupled to a first suture guide of the delivery apparatus via one or more first sutures, wherein a proximal end portion of the prosthetic valve is releasably coupled to a second suture guide of the delivery apparatus via one or more second sutures, and wherein the prosthetic valve, the first suture guide, and the second suture guide are disposed within the sheath;
advancing the sheath together with the prosthetic valve to an implantation location within the native annulus;
retracting the sheath to expose the prosthetic valve, the first suture guide, and the second suture guide from the sheath; and
after the prosthetic valve, the first suture guide, and the second suture guide are exposed from the sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by moving the first suture guide and the second suture guide toward each other;
wherein after moving the first suture guide and the second suture guide toward each other, the method further comprises reducing tension in the first sutures and the second sutures.

12. A method for delivering a prosthetic valve to a native annulus of a heart, comprising:
inserting a sheath of a delivery apparatus into a patient's body, wherein a distal end portion of the prosthetic valve is releasably coupled to a first suture guide of the delivery apparatus via one or more first sutures, wherein a proximal end portion of the prosthetic valve is releasably coupled to a second suture guide of the delivery apparatus via one or more second sutures, and wherein the prosthetic valve, the first suture guide, and the second suture guide are disposed within the sheath;
advancing the sheath together with the prosthetic valve to an implantation location within the native annulus;
retracting the sheath to expose the prosthetic valve, the first suture guide, and the second suture guide from the sheath; and
after the prosthetic valve, the first suture guide, and the second suture guide are exposed from the sheath, expanding the prosthetic valve from a radially compressed state to a radially expanded state by moving the first suture guide and the second suture guide toward each other;
wherein the first suture guide is coupled to a first shaft of the
