Abstract

A method for percutaneously replacing a heart valve of a patient. In some embodiments the method includes the steps of percutaneously delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; expanding the anchor to a deployed configuration in which the anchor contacts tissue at a first anchor site; repositioning the anchor to a second anchor site; and deploying the anchor at the second anchor site.

Claims

1. A method of replacing a heart valve, comprising:

delivering a replacement valve and an expandable anchor within a delivery device to a vicinity of a heart valve, wherein the expandable anchor has a delivery configuration within the delivery device, a partially-deployed configuration when unconstrained by the delivery device, and a fully deployed configuration;

wherein the expandable anchor comprises a metallic frame having a plurality of closed cells, a first end, and a plurality of eyeholes at the first end;

wherein the expandable anchor further comprises a plurality of posts coupled to a second end of the metallic frame, the plurality of posts being configured to engage the plurality of eyeholes in the fully deployed configuration;

expanding the expandable anchor from the delivery configuration to the partially-deployed configuration without use of a balloon; and

repositioning the expandable anchor while the expandable anchor is in the partially-deployed configuration, wherein the repositioning step occurs without retrieving the expandable anchor into the delivery device.

2. The method of claim 1, further comprising expanding the expandable anchor to the fully deployed configuration without use of a balloon.

3. The method of claim 1, further comprising pulling on the expandable anchor to reposition the expandable anchor.

4. The method of claim 1, further comprising pushing on the first end of the metallic frame.

5. The method of claim 1, further comprising expanding the expandable anchor to the fully deployed configuration by pulling on the plurality of posts.

6. The method of claim 1, wherein the plurality of posts includes a plurality of interlocking elements, the plurality of interlocking elements being interlocked with the plurality of eyeholes when the expandable anchor is in the fully deployed configuration.

7. The method of claim 1, further comprising radially expanding the expandable anchor within a patient'"'"'s native heart valve.

8. The method of claim 1, wherein the metallic frame is formed from a shape memory material.

9. The method of claim 1, wherein the expandable anchor further comprises a plurality of control wires routed through the plurality of eyeholes.
