Abstract: A system for treating a cardiac valve includes an adjustable annuloplasty ring configured to attach to or near a cardiac valve annulus. The system also includes a suture comprising a first end coupled to the annuloplasty ring. A second end of the suture is configured to be anchored to a papillary muscle. Selectively adjusting the annuloplasty ring adjusts a tension of the suture to reposition the papillary muscle.

Abstract: A mechanical prosthetic heart valve, includes an annular support (12) on which at least two movable flaps (18, 20, 22) and several articular extensions (32, 34, 36) are arranged in an articulated manner. Each flap includes a central part (38) framed by two lateral wings that each cooperate with an articular extension by way of an end portion that has an articulation facet. The two articulation facets of each flap together make up a surface area of less than 5% of the total outer surface area of the flap.

Abstract: A cardiovascular valve and assembly that facilitates valve installation and exchange. A mechanical cardiovascular valve having multiple sections and/or folding components provides easier valve installation. The cardiovascular valve assembly includes an exchangeable mechanical or bioprosthetic valve and a docking station to allow convenient replacement of a first valve with a second valve of the same or different type.

Abstract: A vessel valve including a sleeve or ring having a central opening and openable and closeable flap elements intended to allow the flow of blood through the central opening in one direction, whereas the flap elements are designed as circle segments, and the sector angle is 360 ? ° n wherein n is a number of circle segments and is equal to 3, 4, 5 or 6, and wherein each flap element at its outer edge is pivotably connected to an inwardly directed flange on the inside of the ring so that in a closed position they co-operate to form a sealing body and in an open position they allow free passage of blood. The ring is composed of n sections, whose pair-wise juxtaposed ends form recesses in the flange accommodating hinge elements which are arranged in the middle of the outer edge of each of the flap elements and which with assembled sections are locked by undercutting; and a method for the manufacture of such vessel valve.

Abstract: A mechanical heart valve prosthesis has a generally rectangular orifice and two leaflets that move between a closed position nearly perpendicular to blood flow and an open position nearly parallel to blood flow. Due to the uniform dimension of a rectangle, the leaflets are hinged at the periphery of the orifice, and present a single large central flow region to the blood when opened. The base provides several means of constraining the leaflet rotation during opening and closing.
