Methods for endovascularly replacing a patient's heart valve. In some embodiments, the method includes the steps of endovascularly delivering a replacement valve and an anchor to a vicinity of the heart valve, the anchor having a braid, and expanding the braid to a deployed configuration against the patient's tissue. The braid may be fabricated from a single strand of wire and/or may comprise at least one turn feature.
1. An apparatus to replace a heart valve, comprising: an expandable anchor and a replacement heart valve,wherein the expandable anchor has a delivery configuration, a fully deployed configuration, and a locking mechanism comprising a longitudinally extending member and a receiving member attached to
1. An apparatus to replace a heart valve, comprising: an expandable anchor and a replacement heart valve,wherein the expandable anchor has a delivery configuration, a fully deployed configuration, and a locking mechanism comprising a longitudinally extending member and a receiving member attached to the interior of the expandable anchor, at least a portion of the longitudinally extending member inserted into the receiving member when the expandable anchor is in the fully deployed configuration, the replacement heart valve is at least partially disposed within the expandable anchor when the expandable anchor is in the fully deployed configuration, the replacement heart valve directly attached to the longitudinally extending member;wherein the anchor comprises a braided shape memory material, andwherein in the fully deployed configuration, a first end of the expandable anchor is bent to form a double layer portion of the anchor, the first end having a plurality of edge cells that are inwardly canted. 2. The apparatus of claim 1 wherein the replacement heart halve has a delivery configuration, and wherein the expandable anchor and the replacement heart valve are spaced apart in their delivery configurations to reduce a delivery profile of the apparatus. 3. The apparatus of claim 1 wherein a proximal end of the replacement heart valve is disposed proximally relative to a proximal end of expandable anchor when the expandable anchor is in the fully deployed configuration. 4. A heart valve apparatus comprising: an expandable anchor and a replacement heart valve;wherein the expandable anchor has a delivery configuration, a fully deployed configuration, and a locking mechanism comprising a longitudinally extending member and a receiving member attached to the interior of the expandable anchor, at least a portion of the longitudinally extending member inserted into the receiving member when the expandable anchor is in the fully deployed configuration, the replacement heart valve is at least partially disposed within the expandable anchor when the expandable anchor is in the fully deployed configuration, the replacement heart valve directly attached to the longitudinally extending member;wherein the anchor comprises a braided shape memory material. 5. The heart valve apparatus of claim 4, wherein the longitudinally extending member comprises a male interlocking element. 6. The heart valve apparatus of claim 5, wherein the receiving member catch comprises a female interlocking element.
