Methods and Apparatus for Endovascularly Replacing a Heart Valve
First Claim
1. A system comprising:
- an implantable medical device comprising an expandable anchor configured to be implantable within a patient;
a post engaged to the anchor, a proximal end of the post comprising an actuator attachment element;
a release actuator defining a lumen; and
an actuator extending through the lumen of the release actuator, a distal end of the actuator comprising a post attachment element, the post attachment element configured to releaseably engage the actuator attachment element of the post,wherein the actuator attachment element extends into the lumen of a distal end of the release actuator.

Abstract
The invention includes methods of and apparatus for endovascularly replacing a heart valve of a patient. One aspect of the invention provides a method including the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; and applying an external non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to change the shape of the anchor, such as by applying proximally and/or distally directed force on the anchor using a releasable deployment tool to expand and contract the anchor or parts of the anchor. Another aspect of the invention provides an apparatus including a replacement valve; an anchor; and a deployment tool comprising a plurality of anchor actuation elements adapted to apply a non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to reshape the anchor.
