Abstract
A device for placement in a biological tissue fluid conduit includes an outer frame, multiple stabilizer arms, an inner frame, and a valve. The outer frame circumferentially surrounds a longitudinal axis and defines an interior passageway. The outer frame has an interior side facing the longitudinal axis and passageway, and an exterior side opposite the interior side. The stabilizer arms extend outward from the outer frame. The inner frame is positioned in the passageway and circumferentially surrounds the longitudinal axis with at least a longitudinal portion of the inner frame circumferentially surrounded by the outer frame. The inner frame has an exterior side facing the interior side of the outer frame. The valve is housed by the inner frame and is configured to restrict fluid flow through the passageway in at least one of two longitudinal directions.

21. A device for placement in a biological tissue fluid conduit comprising:
-
an anchor frame circumferentially surrounding a longitudinal axis and defining an interior passageway, the anchor frame having an interior side facing the longitudinal axis and passageway, and an exterior side opposite the interior side, the anchor frame configured for engaging with inner facing walls of a biological tissue to anchor the device thereabout; a valve housing circumferentially surrounding the longitudinal axis; and a valve housed by the valve housing and configured to restrict fluid flow through the passageway in at least one of two longitudinal directions. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 41, 42, 43, 44)

45. A device for placement in a biological tissue fluid conduit comprising:
-
an anchor frame circumferentially surrounding a longitudinal axis and defining an interior passageway, the anchor frame having an interior side facing the longitudinal axis and passageway, and an exterior side opposite the interior side, the anchor frame configured for engaging with inner facing walls of a biological tissue to anchor the device thereabout; a valve housing circumferentially surrounding the longitudinal axis wherein the valve housing is free from stent wires and formed from non-metallic material; and a valve housed by the valve housing and configured to restrict fluid flow through the passageway in at least one of two longitudinal directions.
