    摘要: A stent for insertion into a vessel of a patient, comprising: a tubular member having a first smaller diameter for insertion into the vessel, and a second larger diameter for deployment within the vessel, and defining a longitudinal axis, said tubular member including a central portion comprised of a plurality of helical circumferential windings separated by a helical space, each of said windings including a plurality of undulations, with each said undulation being defined by two adjacent struts and a loop connecting said struts, at least one cylindrical end portion at an end of said central portion and, a transition zones between said central portion and each of said cylindrical end portions, said transition zone including a plurality of transition undulations having struts that progressively increase in length, wherein a relatively longer strut of said transition undulations has a relatively wider width than a relatively shorter strut of said transition undulations.

    摘要: A stent delivery system includes an inner tubular member on which a stent is loaded, an outer jacket extending over said inner tubular member, the retraction of which causes deployment of the stent, and a handle adapted to move the jacket relative to the inner tubular member. The outer jacket has a tri-layer construction. The constructions of the inner tubular member and outer jacket and the handle provide increased control of the relative movement of the outer jacket relative to the inner tubular member, and prevention of premature release of the stent from the deployment instrument, and greater control over stent deployment among other advantages.
