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.
Claims25
A method of forming a prosthetic valve for implantation within a body lumen, comprising
- providing a radially collapsible trellis having a tubular body scaffold portion defining an elongate fluid passageway for fluid flow therethrough and a valve leaflet frame portion having a number of valve leaf frames each defining a valve leaf frame aperture with the scaffold portion wherein said valve leaf frames are deflectable with respect to said scaffold portion so as to extend in overlying registry with the passageway between a first position and a second position, and
- sealing each said valve leaf aperture with a biocompatible non-thrombogenic fluid impermeable material such that when the leaflet portion is in said first position, fluid flow through said passageway is substantially restricted.
