Abstract

The endovalve comprises an endoprosthesis deployable between a contracted state and an expanded state. The endoprosthesis defines an internal duct. The endovalve includes a valve placed in the internal duct and movable between a closed configuration shutting the duct and a release configuration leaving the duct open. The endovalve has connection means between the valve and the endoprosthesis. The connection means comprise at least one intermediate connection member connected to the endoprosthesis and including at least one region that is movable relative to the endoprosthesis. The valve is fastened to the movable region.

Claims

1. An endovalve of the type comprising:

an endoprosthesis deployable between a contracted state and an expanded state, the endoprosthesis defining an internal duct;

a valve placed in the internal duct and movable between a closed configuration shutting the internal duct and a release configuration leaving the internal duct open; and

connection means between the valve and the endoprosthesis;

wherein the connection means comprise at least one intermediate connection member connected to the endoprosthesis and including at least one region that is movable relative to the endoprosthesis, the valve being fastened to the or to at least one movable region.

2. An endovalve according to claim 1, wherein the endoprosthesis has a side wall defining at least one transverse opening, opening into the internal duct and to the outside of the endoprosthesis through the side wall, the assembly formed by the intermediate connection member and the valve being engaged in the transverse opening.

3. An endovalve according to claim 2, wherein the assembly formed by the valve and the intermediate connection member is movable locally relative to the side wall over a stroke that is defined by the transverse opening.

4. An endovalve according to claim 2, wherein the intermediate connection member has an outside region placed outside the endoprosthesis and an intermediate region connecting the or each movable region via a transverse opening of the endoprosthesis.

5. An endovalve according to claim 1, wherein the intermediate connection member is movable locally along its entire length relative to the endoprosthesis.

6. An endovalve according to claim 1, wherein the intermediate connection member is placed outside the endoprosthesis, the valve being fastened to the intermediate connection member via at least one transverse opening formed in the endoprosthesis along a line of fastening.

7. An endovalve according to claim 6, wherein the intermediate connection member is of a shape that is substantially complementary to the shape of the line of fastening.

8. An endovalve according to claim 1, wherein the intermediate connection member is a filamentary tie.

9. An endovalve according to claim 1, wherein the intermediate connection member is a ribbon.

10. An endovalve according to claim 1, wherein the intermediate connection member is a tubular sleeve placed around the endoprosthesis.
