  • Publication number: 20230210515
    Abstract: A tissue anchor system is provided that includes a first tissue anchor, a second tissue anchor that is separate and distinct from the first tissue anchor, and one or more tethers, which are configured to couple the first tissue anchor to the second tissue anchor. When the first tissue anchor is unconstrained, a head thereof is coaxial with an axis of a shaft thereof, and a tissue-coupling element thereof extends from a distal end of the shaft, is generally orthogonal to the axis, and is shaped such that if the tissue-coupling element were to be projected onto a plane that is perpendicular to the axis, at least 80% of an area of a projection of the tissue-coupling element on the plane would fall within a first angle of 180 degrees in the plane having a vertex at the axis. Other embodiments are also described.

  • Patent number: 11497485
    Abstract: A tissue anchor is provided that includes a head connected to a shaft, and a tissue-coupling element extending from the shaft. The shaft includes a seal that is configured to form a blood-tight seal between the shaft and a heart wall, and to promote hemostasis. When the tissue anchor is unconstrained, the head is coaxial with an axis of the shaft, and the tissue-coupling element is generally orthogonal to the axis and is shaped such that if the tissue-coupling element were to be projected onto a plane that is perpendicular to the axis, at least 80% of an area of a projection of the tissue-coupling element on the plane would fall within a first angle of 180 degrees in the plane having a vertex at the axis. Other embodiments are also described.

  • Patent number: 11484303
    Abstract: A tissue anchor is provided for delivery by a deployment tool in a constrained state, the tissue anchor including a shaft; a tissue-coupling element, which includes a wire including a shape-memory alloy; and a flexible elongate tension member, which is distinct from the wire. The flexible elongate tension member includes a distal portion that is fixed to a site on the wire such that, when the tissue anchor is not constrained by the deployment tool, the flexible elongate tension member applies, to the tissue-coupling element, tension that constrains lateral expansion of the tissue-coupling element away from a central longitudinal axis of the shaft, by preventing the tissue-coupling element from automatically assuming a predetermined shape provided by the shape-memory alloy of the wire. Other embodiments are also described.

  • Patent number: 11389152
    Abstract: A tissue anchor includes a shaft, a tissue-coupling element, and a flexible elongate tension member. The tissue-coupling element includes a wire, which is shaped as an open loop having more than one turn when the tissue anchor is unconstrained. The tension member includes a distal portion that is fixed to a site on the open loop, a proximal portion, which has a longitudinal segment that runs alongside at least a portion of the shaft, and a crossing portion, which (i) is disposed between the distal and the proximal portions along the tension member, and (ii) crosses at least a portion of the open loop when the tissue anchor is unconstrained. The tissue anchor is configured to allow relative axial motion between the at least a portion of the shaft and the longitudinal segment of the proximal portion of the tension member when the tissue anchor is unconstrained.

  • Patent number: 11337686
    Abstract: A method is provided including introducing, during a transcatheter procedure, a tissue anchor into a cardiac chamber of a heart of a subject, while a tissue-coupling element of the tissue anchor is constrained by a deployment tool. The tissue-coupling element is delivered distally through a cardiac wall. The tissue anchor is at least partially released from the deployment tool such that the tissue-coupling element is unconstrained by the deployment tool. After the tissue-coupling element is delivered through the cardiac wall and the tissue anchor is at least partially released from the deployment tool, whether the tissue-coupling element overlies a coronary blood vessel is ascertained, and, if the tissue-coupling element overlies the coronary blood vessel, the tissue anchor is rotated until the tissue-coupling element no longer overlies the coronary blood vessel. Thereafter, the tissue-coupling element is proximally pulled by applying tension to the tissue anchor. Other embodiments are also described.

  • Patent number: 10463358
    Abstract: A tissue anchor is provided for delivery in a constrained state within a deployment tool. The tissue anchor includes a tissue-coupling element; a flexible elongate tension member, which includes (a) a distal portion that is fixed to a site on the tissue-coupling element, and (b) a proximal portion, which is slidably disposed through a passage defined by the tissue anchor; and a load-limiting element, which is attached to the flexible elongate tension member. The load-limiting element and the passage are sized and shaped such that the size and shape of the passage prevent proximal movement of the load-limiting element past the passage, such that the load-limiting element limits a total load that can be applied to the tissue-coupling element by the flexible elongate tension member.
