Abstract:
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.
