摘要： At least a portion of fabrics (404) for use in medical devices (10, 100, 2000) is formed from polymeric materials. The fabrics may be uncoated, partially coated or fully coated with one or more layers (402) of a polymer. The fabrics may be used for the leaflets (108) and/or cuffs (106) of prosthetic heart valves (100) and as a component of other medical devices (2000).

摘要： An integrally woven manifold is disclosed including a primary portion having a primary lumen disposed therein, a secondary portion branching off the primary portion, the secondary portion having a secondary lumen disposed therein in fluid communication with the primary lumen, and a first transitional portion connecting the primary portion to the secondary portion, the first transitional portion having a first aperture through which the secondary lumen fluidly communicates with the primary lumen. The primary portion has a first weave pattern, the secondary portion has at least a second weave pattern, and the first transitional portion is free of punctures, cuts, and bursts. A method for forming the integrally woven manifold is disclosed including continuously interlacing warp and weft to form the primary portion, intermittently interlacing the warp and the weft to form the secondary portion, and disengaging and reengaging the warp and the weft to form the first transitional portion.
