摘要： A method and devices for relieving pressure in the left atrium of a patient's heart is disclosed. The method includes using an ablative catheter in a minimally invasive procedure to prepare an opening from the coronary sinus into a left atrium of the patient's heart. Once the opening is prepared, the opening may be enlarged by a technique such as expanding a balloon within the opening. A stent is then placed within the coronary sinus of the patient, with a transverse portion expanding within the opening, allowing blood to flow from the left atrium to the coronary sinus and then to the right atrium. Pressure within the left atrium is thus relieved.

摘要： Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.

摘要： Described embodiments are directed toward centrally-opening leaflet support devices having a frame and one or more support leaflets coupled to the frame forming a hinge where coupled. The described support leaflets have one or more stiffer regions that facilitate the function of a support leaflet to decrease or prevent prolapse of a native valve leaflet. Methods of making and using such valve devices are also described amongst others.

摘要： A prosthetic heart valve with a dihedral guard safety mechanism includes a base, three or more leaflets that extend from the base, hinges located at the connection between the base and each leaflet, allowing the leaflet to rotate, a dihedral guard that protrudes out from the inner edge of the base, and a dihedral guard slot on the bottom face of each leaflet that forms a flush connection with the dihedral guard safety mechanism when the prosthetic heart valve is in a closed position. The dihedral guard is set at a specified angle and lays under each leaflet, preventing the leaflets from falling to a position or angle lower than the dihedral guard when the valve is subject to negative pressure, in turn, mitigating a potential prosthetic heart valve failure.

摘要： The invention relates to a prosthetic valve (1) for regulating fluid flow between an upstream side (4) and a downstream side (5) and being operable between an open status and a closed status. The prosthetic valve comprises: —an orifice (2) arranged in a surrounding member (3) and extending between the upstream side (4) and the downstream side (5) wherein in the open status of the prosthetic valve (1) the fluid flow through the orifice is maximally enabled and wherein in the closed status of the prosthetic valve the fluid flow through the orifice in a restriction direction (21) from the downstream side (5) to the upstream side (4) is restricted; and—a leaflet (6) arranged in the orifice and being operable between an open status corresponding to the open status of the prosthetic valve and a closed status corresponding to the closed status of the prosthetic valve. The prosthetic valve further comprises regurgitation means (8, 15, 115, 22) arranged in the prosthetic valve for achieving regurgitation in the restriction direction and arranged for becoming ineffective after a period of deployment.

摘要： A prosthetic heart valve includes a radially expandable annular frame and a valve body disposed inside the frame. The valve body includes three leaflets configured to regulate the flow of blood through the frame in one direction. The prosthetic heart valve also includes an annular inner skirt secured to an inner surface of the frame. The inner skirt, has an inflow edge oriented toward an inflow end of the frame, an outflow edge oriented toward an outflow end of the frame, and first and second lateral edges extending from the inflow edge to the outflow edge, wherein the first lateral edge and the second lateral edge are secured together. The first lateral edge and the second lateral edge are oriented at an oblique angle relative to a plane that is perpendicular to a central longitudinal axis of the frame.

摘要： Valve devices for replacement of mitral valves while preserving valvular and subvalvular mitral valve apparatus. The valve device may be configured as a double orifice valve replacement device, and may include an anchoring and manifold assembly coupleable to a delivery catheter. The assembly may include means for anchoring the device to the mitral valve or to a fixation device already attached to the mitral valve. A peripheral ring anchoring system secured to the assembly may include at least one expandable anchoring ring that is expandable within an orifice of the mitral valve so as to surround the orifice perimeter. A helical suture may be helically disposable about the ring, securing the ring to adjacent leaflet tissue. A trap door valve including a trap door body that seals against the anchoring ring during systole and unseals during the diastolic portion of the cardiac cycle may be provided.

摘要： A prosthetic mitral valve with a compressible and expandable base structure that, when expanded, is circumferentially oval, elliptical, or D-shaped, with a major axis and a minor axis ratio of from about 3:4 to about 4:5. Embodiments of the base structure comprise a primary member and a secondary member surrounding the primary member and coupled thereto. Three flexible leaflets are attached to commissure sections of the primary member in a tri-foil configuration. Embodiments of the prosthetic mitral valve include an atrial ring disposed at the inflow end of the stent.
