    摘要: A tubular graft/stent comprises a tubular sheath having at intervals along its length a plurality of ring-like rigid members, which are attached to the sheath around their respective circumferences and are made of a shape memory material, so that when the members change shape the sheath adopts a new cross section in conformity with the members along the sheath's whole length. The members may be discontinuous to allow the adoption of a contracted shape in the martensitic phase and an expanded shape in the austenitic phase. A graft may also have a branched side tube which can be inverted so as to be housed within the sheath.

    摘要: A method for stitching thread onto the wall of a tubular medical implant (preferably a graft) employs a sewing machine with an elongate bobbin or a needle on an elongate element, depending on whether it is desired to sew from the outside-in or the inside-out. A motor rotates and translates the implant, which is mounted on a hollow drum, relative to the needle.
