    Abstract: A replacement heart valve system may include a delivery sheath and a replacement heart valve. The replacement heart valve may include a mesh anchor member disposed within the delivery sheath in an elongated delivery configuration, the mesh anchor member being expandable to a deployed configuration when unconstrained by the delivery sheath. The mesh anchor member may include an upstream chamber, a downstream chamber, and a tubular middle portion extending between the upstream chamber and the downstream chamber. The replacement heart valve may include a diaphragm disposed within the downstream chamber of the mesh anchor member, wherein the diaphragm is configured to selectively prevent fluid flow through the replacement heart valve.

    Abstract: A stent including a tubular body having first and second opposing open ends and a lumen extending therebetween. The stent including a first anchor member disposed adjacent the first open end and a second anchor member disposed adjacent the second open end, the first and second anchor members spaced apart by a saddle region of the tubular body, the first and second anchor members each extending radially outward from the tubular body, the first and second anchor members each have an outer diameter larger than an outer diameter of the saddle region disposed between the first and second anchor members. Each of the first and second anchor members include an outer wall, and an inner wall spaced apart from the outer wall, and the tubular body is defined by only a single wall.

    Abstract: An example medical device may include a stent including a radially expanding tubular framework having a radially outward surface, a radially inward surface, a first end region, a second end region, a medial region positioned between the first end region and the second end region, and a lumen extending from the first end region to the second end region. A first flange structure may be positioned near the first end region, and a second flange structure may be positioned near the second end region. One of the first end region or the second end region may include a third flange structure.

    Abstract: An example medical device includes a stent having a radially expanding tubular framework. The radially expanding tubular framework includes a first end region, a second end region, a medial region positioned between the first end region and the second end region, and a lumen extending from the first end region to the second end region. The stent further includes a tubular structure positioned over the medial region, the tubular structure is formed from a bioabsorbable material, and is configured to hold the medial region in a first, compressed configuration. Upon bioabsorption of the tubular structure, the medial region of the tubular framework radially expands to a second, expanded configuration. One of the first end region or the second end region includes a first flange structure.
