Abstract
An implantable flow modifying device and a method of modifying flow through a lumen are provided. The flow modifying device includes a flexible member configured for permitting fluid flow through the body lumen in a first direction at a first rate and for restricting fluid flow through the body lumen in a second direction at a second rate. The flexible member includes a passageway defined by a sheath of biocompatible material, the passageway having a first end portion and a second end portion. The first end portion is sized and shaped to at least partially restrict fluid flow in the first direction and capable of at least partially collapsing in response to fluid flow in the second direction. The second end portion is adapted to seal with a wall of the body lumen. A diameter of a first opening defined in the first end portion is smaller than a diameter of a second opening defined in the second end portion.
