    Abstract: A method for endovascularly replacing a heart valve of a patient. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor in an unexpanded configuration within a catheter to a vicinity of the heart valve; deploying the anchor from the catheter; expanding the anchor to contact tissue at an anchor site; and retrieving the anchor into the catheter. The invention also includes an apparatus for endovascularly replacing a heart valve, including: a catheter; a replacement valve configured to be disposed within the catheter for delivery to a vicinity of the heart valve; and an expandable anchor configured to be disposed within the catheter for delivery to a vicinity of the heart valve, to be deployed from the catheter, to be expanded to contact tissue at an anchor site and to be retrieved back into the catheter after having been expanded.

    Abstract translation: 一种用于血管内置换患者心脏瓣膜的方法。 在一些实施例中，该方法包括以下步骤：将导管内的未膨胀构造的置换瓣膜和可扩张锚固件输送到心脏瓣膜附近; 从导管部署锚杆; 扩大锚点​​以在锚点处接触组织; 并将锚固件取回到导管中。 本发明还包括用于血管内置换心脏瓣膜的装置，包括：导管; 配置成设置在所述导管内用于输送到所述心脏瓣膜附近的置换瓣膜; 以及被构造成设置在所述导管内用于输送到所述心脏瓣膜附近以从所述导管展开的可扩张锚，以被扩张以在锚固部位接触组织并且在扩张后被回收回到所述导管中 。

    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.
