摘要: Apparatus is provided, including a radially-expandable percutaneous implant, a tissue anchor, and a connecting element shaped so as to provide an annular loop surrounding a proximal portion of the tissue anchor in a manner which enables rotation of the anchor about a central longitudinal axis thereof when surrounded by the annular loop. The apparatus also includes a flexible longitudinal member coupled at a first portion thereof to at least a portion of the percutaneous implant and at a second portion to the connecting element. The annular loop of the connecting element facilitates rotation of the tissue anchor about the central longitudinal axis such that the anchor can rotate about the central longitudinal axis with respect to the annular loop, the flexible longitudinal member, and the percutaneous implant. Other applications are also described.

摘要: Apparatus is provided including a stent, which is configured to assume compressed and expanded states. The stent includes one or more elongated members, and two or more rings, which are coupled together by the one or more elongated members and by no other elements of the stent. The rings define respective planes that are generally perpendicular to the elongated members when the stent is in its expanded state. A longitudinal member, having a proximal end and a distal end, is coupled to the stent at the proximal end of the longitudinal member. A tissue anchor is coupled to the distal end of the longitudinal member. Other applications are also described.

摘要: An annular prosthesis for a mitral valve that may include a posterior half-ring and an anterior half-ring coupled to each other on a first transverse plane which defines a maximum width section of the prosthesis. The ratio between the distance between the anterior half-ring and the posterior half-ring, as measured along a second plane, perpendicular to the first plane and equidistant to the couplings, and the maximum width of the prosthesis is lower than ¾.

摘要: A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a minor axis, both perpendicular to a blood flow axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. Viewed another way, the convexity of the P3 segment is less pronounced than the convexity of the P1 segment. In addition, the ring body may have a downwardly deflected portion in the posterior section, preferably within the P2 and P3 segments. The downwardly deflected portion may have an apex which is the lowest elevation of the ring body and may be offset with respect to the center of the downwardly deflected portion toward the P1 segment. A sewing cuff may have an enlarged radial dimension of between 5-10 cm, or only a portion of the sewing cuff may be enlarged.
