Abstract
Vascular prosthetic assemblies (e.g., heart valves), such as those, for example, configured to be deployed percutaneously.
Claims3
A method of manufacturing a vascular prosthetic assembly, the method comprising:
- pouring a cellulose-based mixture over a mandrel to form a first cellulose-based layer;
- submerging the first cellulose-based layer in a first liquid;
- placing a generally tubular frame around the first cellulose-based layer;
- pouring the cellulose-based mixture over the generally tubular frame and the first cellulose-based layer to form a second cellulose-based layer;
- submerging the first cellulose-based layer and the generally tubular frame, and the second cellulose-based layer in the first liquid;
- and
- submerging the first cellulose-based layer, the generally tubular frame, and the second cellulose-based layer in a second liquid.
