Stents for prosthetic heart valves and methods of making same
A single piece stent construction having a plurality of commissure posts, each of which extends upwardly from a solid ring along a bend line and generally along a central longitudinal axis of the stent.
1. A tubular stent having a single-piece construction, the stent comprising:
a solid ring having a central opening;
a plurality of shaped members extending upwardly from the ring and spaced from each other around a circumference of the ring, wherein an outer circumference of the tubular stent comprises the plurality of shaped members;
at least one sinusoidal structure having a plurality of peaks and valleys, wherein the sinusoidal structure is spaced from the solid ring and positioned between adjacent shaped members; and
at least one support member extending upwardly from the solid ring to a valley of the sinusoidal structure.
2. The stent of claim 1 , wherein each of the shaped members comprises at least one aperture.
3. The stent of claim 1 , in combination with a prosthetic valve that is attached to each of the shaped members and positioned within an interior area of the tubular stent, wherein the valve comprises a leaflet extending between each pair of shaped members.
4. The stent of claim 1 , wherein each of the shaped members extends in a direction that is generally parallel to a central longitudinal axis of the tubular stent.
