    摘要: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

    摘要: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

    摘要: A prosthetic valve assembly includes a support structure and a valve component. The support structure includes a first frame and a sealing member. The first frame includes a lumen extending between inflow and outflow ends. The sealing member extends inwardly into the lumen of the first frame and includes a first end wall defining a first orifice, a second end wall axially spaced from the first end wall and defining a second orifice, and an inner sleeve extending axially from the first end wall to the second end wall and spaced radially inwardly from the first frame. The valve component includes a second frame and a valve structure supported inside of the second frame for permitting blood flow through the valve component in one direction and blocking blood flow in the opposite direction. The valve component is configured to expand within and engage the inner sleeve of the sealing member.
