  • Patent number: 10413400
    Abstract: A prosthetic heart valve having a pair of cooperating leaflets mounted in a valve body to alternate between an open position where the flow of blood in a downstream direction is permitted and a closed position where the flow of blood in the reverse direction is counteracted. Pivot member sets at diametrically opposite sides of each leaflet guide the leaflets moving between the open and closed positions, each set including an ear or a recess cooperating with an associated cavity or knob of an interior surface of the valve body. Each ear or recess bounds at least one leaflet passageway through that ear or recess and located spaced from upstream and downstream ends of the ear for allowing flow through that ear and the associated cavity, or through that recess, when the leaflets are in the closed positions.

  • Patent number: 8979922
    Abstract: A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6). A failed or failing mitral heart valve (101) is treated by percutaneously locating the valve body (2) in the mitral valve orifice (102) with the anchor device (5) located in the right atrium (107) and engaging the inter-atrial septum (103), such that the taught anchor line (6) acts to secure the valve body (2) within the mitral valve orifice (102).

  • Patent number: 8685083
    Abstract: The invention is an apparatus, system, and method for repairing heart valves. A suture line is secured to a papillary muscle, and then passed through a portion of a heart valve leaflet. A reference element is provided at a desired distance from a plane defined by the heart valve annulus. The suture line is secured to the heart valve leaflet at a position adjacent the reference element. The reference element may part of a device configured for placement on or in a heart valve annulus. The reference element may be slidingly secured to the device so that the distance of the reference element from the main body of the device can be varied by a surgeon or other user. The reference element may be a line of suture, which may be pre-installed during manufacture of the device or may be installed by the surgeon or other user.

  • Patent number: 6991649
    Abstract: In an artificial heart valve for the replacement of an aortic or a mitral valve, including an annular body, which is provided at its outer circumference with means for mounting the artificial valve in place by surgical procedures and which defines in its interior a blood flow passage in which valve flap elements are pivotally supported so as to open or close the blood flow passage depending on their pivot positions, the annular body includes circumferentially spaced projections extending into the flow passage and being provided at their inner ends with pivot joints on which the valve flap elements are pivotally supported.
