Implantable prosthetic valve
First Claim
Patent Images
1. A valve, comprising:
- a radially-elastic scaffold with valve leaflet frames having an open-frame construction; and
an elongate liner adjacent the radially-elastic scaffold and valve leaflet frames to provide a fluid passageway, where the elongate liner includes excess material to provide a concave shape to the elongate liner extending into the open-frame construction, and where the valve leaflet frames with the elongate liner move between a closed position to restrict fluid flow through the fluid passageway and an open position to allow fluid flow through the passageway.

Abstract
A prosthetic valve for implantation within a fluid conducting lumen within a body includes an elongate generally cylindrical radially collapsible valve body scaffold defining a fluid passageway therethrough for retentive positioning within the lumen. A radially collapsible leaf valve member is supported by the scaffold includes a number of valve leafs deflectable between a closed position restricting fluid flow through the passageway and an open position permitting fluid flow through the passageway. The leaf valve member includes an interior leaf valve frame defining a valve leaf aperture which is sealed by a fluid impermeable non-thrombogenic lining to prevent fluid flow therethrough.

8. A valve, comprising:
-
a radially deformable unitary open-frame scaffold having a tubular body and valve leaflet frames; and a liner at least partially encasing the radially deformable unitary open-frame scaffold to provide a fluid passageway, where the liner includes excess material to provide a concave shape to the liner extending into the open-frame scaffold, and where the valve leaflet frames with the liner move between a closed position to restrict fluid flow through the fluid passageway and an open position to allow fluid flow through the passageway. - View Dependent Claims (9, 10, 11, 12, 13)
