ABSTRACT:
A stent includes a lattice defining a substantially cylindrical configuration having a proximal end portion and a distal end portion, and a middle portion between the proximal end and the distal end. The lattice being moveable from a crimped state to an expanded state, and a plurality of adjacent hoops. Each hoop has a plurality of adjacent loops. Additionally, the stent further includes a plurality of bridges connecting adjacent hoops and a plurality of extensions on the lattice. Each of the hoops and bridges define a cell. The proximal end portion and the distal end portion of the lattice have at least one cell respectively and the middle portion of the lattice has at least one cell. The plurality of extensions are on the middle portion of the lattice. The plurality of extensions are cantilevered projections from the bridges and/or hoops of the lattice. The plurality of extensions are movably deformable in a direction away from the lattice, for example, at least some of the extensions are movably deformable in a direction away from the bridges and at least some of the extensions are movably deformable in a direction away from the hoops.
