    Abstract: An implantable stent includes a stent retrieval member for repositioning or retrieval of the stent after it has been implanted into a bodily lumen. The stent includes a distensible tubular stent having a tubular structure having a tubular wall defined by an interior surface and an exterior surface and having opposed open ends; and a stent retrieval member comprising an elongate member comprising a generally circular perimetric base and a shaped projection having first and second spaced apart members extending acutely or perpendicularly from the base and connected by an apical portion. Force exerted on the shaped projection causes contraction or expansion of the circular base. The circular base is securably attached to one of the open ends of the stent, and the shaped projection extends longitudinally beyond this open end of the stent.

    Abstract: A device for causing hemostasis includes a sheet of mesh stretchable between an expanded and a retracted configuration, a size of the sheet in the retracted configuration being selected to cover a target tissue site; a spring mechanism coupled to the mesh, the spring mechanism moving between an expanded configuration and a retracted configuration when the mesh is moved between the expanded and retracted configurations; and a plurality of hooks coupled to the mesh and oriented to extend into tissue to lock the mesh in position when the mesh is placed in a desired position over the target tissue site in the expanded configuration. The hooks are lockingly engaging the target tissue so that, after the hooks have lockingly engaged the tissue, the spring mechanism reverts to the retracted configuration drawing the engaged portions of tissue radially inward.

    Abstract: An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.
