1. A radially deformable endovascular prosthesis, comprising:
- a lattice deformable between a retracted state wherein said lattice has a small diameter, and an expanded state wherein said lattice has a large diameter;
a pair of external hooks having crook portions configured to define a clamp for anchoring said prosthesis to external tissue, said pair of hooks being mounted to said lattice so as to be movable between a spaced-apart position wherein said crook portions are spaced apart such that said clamp is open, and a close-together position wherein said crook portions are close together such that said clamp is closed;
wherein said lattice includes crossed wires arranged to define meshes, said pair of hooks being connected to said wires of said lattice at opposite sides of one of said meshes of said lattice and are configured such that said pair of hooks cross each other, said lattice having a tubular shape, said pair of hooks being offset circumferentially with respect to each other around said tubular lattice, said lattice and said pair of hooks being configured such that said one of said meshes has a first shape when said lattice is in said retracted state so that said pair of hooks of said clamp are in said spaced-apart position, and such that said one of said meshes has a second shape when said lattice is in said expanded state so that said pair of hooks of said clamp are in said close-together position.

Abstract
The radially deformable tubular prosthesis comprises a lattice that is deformable between a retracted state of small diameter and an expanded state of greater diameter. It includes at least two external hooks defining between them a clamp for hooking in external tissue, the two hooks being carried by the lattice and being movable between a spaced-apart position in which the clamp is open, and a closer-together position in which the clamp is closed.

11. A kit for treating a blood vessel, said kit comprising:
-
a radially deformable endovascular prosthesis, including; a lattice deformable between a retracted state wherein said lattice has a small diameter, and an expanded state wherein said lattice has a large diameter; pair of external hooks having crook portions configured to define a clamp for anchoring said prosthesis to external tissue, said pair of hooks being mounted to said lattice so as to be movable between a spaced-apart position wherein said crook portions are spaced apart such that said clamp is open, and a close-together position wherein said crook portions are close together such that said clamp is closed; wherein said lattice includes crossed wires arranged to define meshes, said pair of hooks being connected to said wires of said lattice at opposite sides of one of said meshes of said lattice and are configured such that said pair of hooks cross each other, said lattice having a tubular shape, said pair of hooks being offset circumferentially with respect to each other around said tubular lattice, said lattice and said pair of hooks being configured such that said one of said meshes has a first shape when said lattice is in said retracted state so that said pair of hooks of said clamp are in said spaced-apart position, and such that said one of said meshes has a second shape when said lattice is in said expanded state so that said pair of hooks of said clamp are in said close-together position; a retaining device for holding said lattice in said retracted state at said clamp, said retaining device being configured to maintain said clamp open by tightening said one of said meshes carrying said pair of hooks; and a lattice delivery tube defining a confinement duct in which said lattice is confined in said refracted state, said retaining device being separate from said lattice delivery tube such that said lattice is releasable from said lattice delivery tube to assume said expanded state while said one of said meshes carrying said pair of hooks remains tightened. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
