Abstract

A heart valve system, the system including a radially self-expandable tubular body and a valve. The tubular body having an inflow end and an outflow end, and the tubular body including a proximal-most end at the inflow end and a distal-most end at the outflow end. The tubular body including a plurality of arched beams at the outflow end of the tubular body such that the arched beams form the distal-most end of the tubular body. Connection points linking the inflow end of the tubular body and the arched beams, a number of connection points being equivalent to a number of the valve leaflets. Each arched beam being directly attached to an adjacent arched beam such that the arched beams are continuous along the entire circumference of the tubular body at the outflow end. The valve being coupled to the tubular body and including a plurality of valve leaflets.

Claims

1. A heart valve system, the system comprising:

a radially self-expandable tubular body having a proximal-most end at an inflow end and a distal-most end at an outflow end;

the tubular body including a plurality of arched beams at the outflow end of the tubular body,

a valve coupled to the tubular body, the valve including a plurality of valve leaflets; and

a fabric that is disposed over an outer surface of the tubular body and does not wrap around the outflow end of the tubular body, the fabric being directly connected to both the arched beams and an outer circumferential edge of the valve,

wherein;

connection points link the inflow end of the tubular body and the arched beams, a number of connection points being equivalent to a number of the valve leaflets,

each arched beam is directly attached to an adjacent arched beam such that the arched beams are continuous along the entire circumference of the tubular body at the outflow end, and

the arched beams and the connection points form the distal-most end of the tubular body.

2. The system according to claim 1, wherein the valve leaflets extend distally of the arched beams in an outflow direction.

3. The system according to claim 1, wherein the arched beams each include a first end and a second end, the first end providing the connection points and the second end forming a commissural attachment area, the second end being distal of the first end in an outflow direction.

4. The system according to claim 1, wherein each valve leaflet is supported by at least two beams of the plurality of arched beams.

5. The system according to claim 4, wherein each valve leaflet is supported by the at least two beams such that the outer circumferential edge of the valve is connected to the at least two beams.

6. The system according to claim 1, wherein the fabric does not extend distally of the distal-most end the tubular body in an outflow direction.

7. The system according to claim 1, wherein the plurality of arched beams includes at least six beams.

8. The system according to claim 1, wherein the distal-most end of the tubular body is connected to one or more retaining components.
