    Abstract: Apparatus for endovascularly replacing a patient's heart valve, including: a replacement valve adapted to be delivered endovascularly to a vicinity of the heart valve; an expandable anchor adapted to be delivered endovascularly to the vicinity of the heart valve; and a lock mechanism configured to maintain a minimum amount of anchor expansion. The invention also includes a method for endovascularly replacing a patient's heart valve. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve; expanding the anchor to a deployed configuration; and locking the anchor in the deployed configuration.

    Abstract: A medical device apparatus may include a medical implant including an anchor member configured to actuate between a delivery configuration and a deployed configuration operatively connected to a delivery system, the delivery system including an outer sheath and an inner catheter disposed within the outer sheath, and a sheathing aid connecting the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon relative closing movement therebetween. The sheathing aid may include a plurality of tethers extending from the inner catheter to a proximal end of the anchor member, and a release mechanism slidably disposed within a coupler ring coupled to a distal end of the inner catheter. The plurality of tethers may be releasably coupled to the release mechanism.

    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.

    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.
