    摘要： A plurality of branch bars is provided on opposing sides of paired strut pieces connected by links in a strut to protrude from one towards the other side, and a plurality of ratchet teeth is formed on the side of the branch bars respectively. When a stent made of polymer material having a cylindrical constitution in which a plurality of struts is connected by links is deformed to enlarge its diameter, the paired struts are deformed to come near to each other, so that the branch bars overlap each other with the ratchet teeth formed thereon engaging with each other. As the effect of engagement of the ratchet teeth with each other, while deformation of the struts so as to enlarge the diameter of the stent is allowed, deformation so as to reduce the diameter of the stent is inhibited.

    摘要： An endovascular stent-graft is provided that includes a generally tubular body, which (a) is configured to assume a radially-compressed delivery state and at least first and second radially-expanded deployment states, (b) is shaped so as to define a stepwise expanding portion, and (c) comprises a stent member. The stent member includes a plurality of self-expandable flexible structural stent elements, and at least one circumferential expansion element. The stent member is configured such that application of a force thereto, which is insufficient to cause plastic deformation of the self-expandable flexible structural stent elements and is sufficient to cause plastic deformation of the circumferential expansion element, causes an increase in a circumferential length of the circumferential expansion element, thereby transitioning the tubular body from the first radially-expanded deployment state to the second radially-expanded deployment state, thereby increasing a greatest internal perimeter of the expanding portion.

    摘要： Described herein are radially self-expanding stents. The disclosed stents can be used to widen arteries and/or veins of a patient to counteract or combat narrowing of the arteries and/or veins associated with certain congenital diseases, such as aortic coarctation. As an example, the disclosed stents are configured to be placed at or near a narrowed portion of the aorta where the stent produces a radial outward force on the aorta. The radial force produced by the stent widens the aorta and causes the stent to expand with the aorta. The disclosed stents can be crimped to relatively small sizes for placement in small patients (e.g., less than about 10 kg in size) and can be configured to expand to widen the aorta and to accommodate growth in the patient.

    摘要： A stent including a tubular body formed of one or more interwoven wires, a first anchor member disposed adjacent the first open end of the stent, a second anchor member disposed adjacent the second open end of the stent, and at least one divider disposed between the first and second anchor members. The first and second anchor members and the divider extend radially outward from the tubular body to divide the tubular body into at least a first saddle region extending between the first anchor member and the divider and a second saddle region extending between the second anchor member and the divider.

    摘要： A braided stent system includes a stent body having a lumen formed by a plurality of braided members with interstices formed therebetween and a first expansion ring connected to the lumen of the stent body. The first expansion ring may include a frame defined by a plurality of interconnected support assemblies that are selectively positioned to impart an outwardly expanding radial force to the stent body, each support assembly can include a plurality of legs joined at a first intersection and connected to one of the other interconnected support assemblies at a second intersection opposite the first intersection. Each support assembly can include a claw portion mechanically connected to one or more of the interstices of the stent body so that the frame imparts an outward radial expansion force of the stent to facilitate use and delivery of the stent.
