1. An expandable stent, comprising:
a tubular scaffold formed of one or more interwoven filaments, the tubular scaffold defining a lumen and including an inner surface and an outer surface; and
a flexible valve extending radially inward from the inner surface of the tubular scaffold;
wherein the one or more filaments of the scaffold are configured to shift the flexible valve from an open configuration to a closed configuration;
wherein the one or more filaments are biased radially inward to hold the flexible valve in the closed configuration while in a nominally deployed state.
