Abstract
A cardiac valve with a support frame having a first end member and a second end member opposing the first end member in a substantially fixed distance relationship, and a cover extending over the support frame to allow for unidirectional flow of a liquid through the valve.
Claims20
A valve defining a valve lumen and comprising:
- a frame;
- a cover attached to the frame, the cover comprising:
- a tubular cover portion;
- and
- flaps, each flap having a variable longitudinal length and a free edge, the flaps constructed and arranged to move between an open state and a closed state for reversibly sealing the valve lumen.
2 more elements
A valve comprising:
- a frame having a longitudinal frame length measured from a first frame end to a second frame end, the longitudinal frame length being uniform, the frame defining a first valve end;
- a cover engaged to an outer surface of the frame, the cover including leaflets movable relative to the frame,
- wherein when the valve is open the cover has a variable longitudinal cover length comprising:
- minimum longitudinal cover lengths equal to the longitudinal frame length, and
- maximum longitudinal cover lengths greater than the longitudinal frame length, each minimum longitudinal cover length is positioned between two maximum longitudinal cover lengths, and each maximum longitudinal cover length is positioned between two minimum longitudinal cover lengths, and a number of locations with the maximum longitudinal cover length is equal to a number of the leaflets.
2 more elements
A valve comprising:
- a tubular frame with a first frame end comprising convex curves and concave curves, each concave curve having a maximum depth and extending between two convex curves;
- and
- flaps for regulating flow through the tubular frame, wherein each flap extends across an area defined between two circumferentially adjacent convex frame portions and has a maximum longitudinal length greater than the maximum depth of the concave curve.
