  • Patent number: 10925761
    Abstract: A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

  • Patent number: 10426643
    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.
