1. A device for regulating blood flow in a patient to treat a condition, the device comprising:
a stent comprising a first flared end region, a second flared end region, a neck region disposed between the first and second flared end regions, and a passageway extending through the first flared end region through the neck region and through the second flared end region, the stent configured to shunt blood between body cavities;
a biocompatible material disposed on the stent to define a sheath that channels blood flow through the passageway; and
a biodegradable material disposed on an inner surface of the biocompatible material at the neck region, the biodegradable material configured to carry a material that inhibits tissue overgrowth across the biodegradable material within the passageway of the stent.
