  • Patent number: 7041126
    Abstract: A flexible self-expandable stent has inside and outside stent bodies each fabricated by knitting first and second super-elastic shape memory alloy wires into a net-like structure with the first wire zigzagged with a diagonal length P interlocked with the second wire zigzagged with a diagonal length 2P at a plurality of interlocked points with intersecting points therebetween to allow the stent bodies to apply force against longitudinal contraction of the stent bodies. The interlocked points and the intersecting points form a plurality of diamond-shaped meshes in the net-like structure of each stent body. A hollow rubber tube is closely fitted between the inside and outside stent bodies, with each of the overlapped ends of the rubber tube and the stent bodies being integrating into a single structure.

  • Patent number: 6994722
    Abstract: A device for improving fixation and sealing of a prosthetic component when implanted in a body lumen during laparoscopic, endovascular, or open surgical procedures. In one embodiment, the prosthetic component comprises a graft having a hem defining an interior space. Enclosed within the space is an absorbent cord. The cord expands as it comes in contact with body fluids. The expansion due to the absorbed fluids forms a seal closely following the irregular shape of the lumen and improves fixation at the junction of the body lumen and the prosthetic component. Hem and cord arrangement also used to improve fixation of one prosthetic component to another in a modular graft. In another embodiment, an attachment tab has one part affixed to the outer periphery of the graft and another part attached to an area adjacent to the body lumen upon implantation, to resist forces tending to move the implant.

  • Patent number: 6939370
    Abstract: A stent graft deployment device adapted for release of a distal end (29) of a stent graft (25) before the proximal end (27) of the stent graft (25). The arrangement (15) allows movement of at least part of the deployment catheter (23) independently of movement of a proximal end release mechanism has a fixed handle (16) associated with a trigger wire release mechanism (6) and a sliding handle (17) to which the deployment catheter and a capsule (21) are fixed. The sliding handle (17) is mounted on the fixed handle (16) and can slide longitudinally with respect to the fixed handle (16).
