    摘要: The disclosure relates to a stent with a compressible and expandable mesh structure of webs which are interconnected by web connectors into one piece and define rhomboid cells, wherein each cell is defined by two straight webs and two S-shaped curved webs which connect the straight webs together, and wherein (i) in a non-operational state, the mesh structure has a fully expanded non-operational diameter Dexp which is between 3.0 mm and 5.0 mm, (ii) a ratio between a fully compressed diameter Dkomp of the mesh structure and the non-operational diameter Dexp of the mesh structure is between 1:7 and 1:12, and (iii) the webs have a web height, measured in a radial direction, which is at least 0.05 mm and at most 0.09 mm, so that the mesh structure has a radial force of at least 0.5 N, in particular at least 0.6 N, between the fully compressed diameter Dkomp and an operational diameter which is at most 90% of the non-operational diameter Dexp.

    摘要: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.
