Abstract:
1. A device for sealing a passageway in a human heart, the device comprising: a first anchor adapted to be placed proximate a first end of the passageway, the first anchor deployable from a collapsed state to an expanded state, the first anchor having an open structure that permits blood to pass through the first anchor when the first anchor is in the expanded state; a second anchor adapted to be placed proximate a second end of the passageway, the second anchor deployable from a collapsed state to an expanded state, the second anchor having a covering for occluding blood flow through the second anchor when the second anchor is in the expanded state; an elongate member adapted to extend through the passageway and connect the first and second anchors; and a locking element positionable on the elongate member; wherein the second anchor is movable along the elongate member relative to the first anchor, wherein the locking element is movable along the elongate member towards the second anchor to secure the location of the second anchor on the elongate member, and wherein the locking element is arranged to engage the outer surface of the elongate member so as to permit movement of the locking element along the elongate member towards the second anchor but resist movement of the locking element along the elongate member away from the second anchor, whereby the locking element is configured to resist movement of the second anchor away from the first anchor along the elongate member.
