    摘要: A system and method for treating a vascular condition includes a conduit having an elongate tubular member with an outer surface and an inner surface, the inner surface defines a conduit lumen. The system further includes at least one symmetry indicator attached to the elongate tubular member and a replacement valve device. The replacement valve device includes a prosthetic valve connected to an expandable support structure. The replacement valve device is positioned within the conduit lumen adjacent the inner surface.

    摘要: A method of manufacturing a stent includes determining a porosity characteristic and combining at least two predetermined alloy constituents based on the porosity characteristic. The method further determines a solidification profile based on the porosity characteristic and combined alloy constituents and solidifies the combined alloy constituents based on the solidification profile. In addition, the method includes forming a stent framework from the solidified alloy constituents, removing at least a portion of at least one of the alloy constituents, and forming pores within the stent framework based on the removal and consistent with the porosity characteristic.
