1. A therapeutic device, comprising:
- a prosthetic heart valve including a collapsible and expandable stent having an aortic section with a first cross-section in an expanded condition and an annulus section with a second cross-section in the expanded condition, the second cross-section being smaller than the first cross-section, the stent including a plurality of struts defining a plurality of cells, and a valve assembly disposed within the annulus section of the stent, the valve assembly including a plurality of leaflets operative to permit blood flow from the annulus section to the aortic section but to substantially block blood flow from the aortic section to the annulus section; and
a graft coupled to the aortic section of the stent, the graft having a body and at least one lining disposed on the body, the body defining a lumen therethrough and including a plurality of legs, each of the legs being formed of a plurality of wire strands, and each of the legs being directly coupled to the aortic section of the stent.
