    摘要: A locking system for transcatheter annuloplasty may be provided with an implantable lock body, a movable member configured to be slidably received in a lock body slot, a tether abutting portion, a coupling element located on a proximal portion of the lock body, a pull wire having a coupling member configured to detachable mate with the coupling element, a flexible catheter configured to slidably receive a portion of the pull wire, and a collar located on a distal portion of the catheter and configured to slidably receive the lock body. The pull wire and the catheter may be pushed together in a distal direction to advance the lock body along a tether, and the pull wire may be pulled in a proximal direction relative to the catheter to move the movable member towards a locked position and lock the tether to the lock body. Methods of use are also provided.

    摘要: An exemplary method of performing an annuloplasty procedure includes introducing a catheter into a left atrium of a heart, deploying a first member from the catheter, anchoring the first member to a posterior side of a mitral valve annulus in the left atrium, deploying a second member from the catheter, anchoring the second member to an anterior side of the mitral valve annulus in the left atrium, deploying a flexible tensile member from the catheter, attaching the tensile member to both the first member and the second member and applying tension to the tensile member to draw the first member and the second member toward one another and bring the posterior side and the anterior side of the mitral valve annulus into closer approximation. Annuloplasty systems and components are also disclosed.

    摘要: The present disclosure relates to an annuloplasty apparatus configured to be implanted into the body of a subject, the annuloplasty apparatus comprising: a contractile bridging element; a bar member connected to the contractible bridging element, the bar member being provided with a rotatable connection mechanism; and a tissue anchor configured to secure the bar member to the annulus tissue by the rotatable connection mechanism, and comprising: a head portion; and a helical tissue coupling element, the proximal end of which is fixed to the head portion, wherein the helical tissue coupling element is configured to be driven into the annulus tissue by rotation, wherein the rotatable connection mechanism is at least partially configured to be rotatable relative to the bar member, thereby allowing the helical tissue coupling element to rotate further relative to the bar member when the proximal end of the helical tissue coupling element is in contact with the rotatable connection mechanism. In this way, the gap between the bar member and the annulus
