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.
Claims48
A prosthetic valve for implantation within a fluid conducting lumen within a body, comprising:
- an elongate radially-collapsible generally cylindrical body scaffold defining an elongate fluid passageway therethrough;
- and
- a radially-collapsible leaf valve member supported by said scaffold and being deflectable between a closed configuration restricting fluid flow through said passageway and an open configuration permitting fluid flow through said passageway, said leaf valve member including a valve leaf frame defining a valve leaf aperture, said valve leaf aperture sealed by a fluid impermeable non-thrombogenic lining so as to continuously prevent fluid flow through said valve leaf aperture.
