Abstract
An apparatus for endovascular replacement of a heart valve may include first and second members which are releasably attached to each other such that the second member participates in engaging the first member with a locking element which cooperates with the first member to lock an expandable anchor of the replacement heart valve in a deployed configuration. Prior to locking and removal of the second member, the locking element may be prevented from engaging the first member by a portion of the second member. Following locking, the second member may be removed.

Apparatus for endovascularly replacing a patient's heart valve comprising:
- a delivery sheath;
- a deployment tool comprising a plurality of anchor actuating elements;
- an expandable anchor adapted to be disposed within the sheath and expanded by the deployment tool following deployment of the expandable anchor from the sheath,
- a replacement valve adapted to be disposed within the sheath for delivery to the vicinity of a heart valve;
- wherein the plurality of anchor actuating elements is adapted to apply a proximally directed force to a distal portion of the expandable anchor;
- a plurality of first members attached to the distal portion of the expandable anchor;
- a plurality of second members individually releasably attached to the first members;
- and
- a plurality of lock elements fixedly attached to a proximal portion of the expandable anchor and adapted to engage the plurality of first members to lock the expandable anchor in a deployed shape,
- wherein each of the first members is adapted to support the replacement valve within the expandable anchor,
- further wherein the plurality of second members each have a first position adapted to prevent release of the first member of a plurality of first members and a second position adapted to permit release of the first member.
