    摘要： A stent-graft having an exo-skeleton attached to a tubular graft, the tubular graft having a peripheral wall defining a lumen therein extending between first and second ends. One or more support elements, defining the exo-skeleton, are attached to the tubular graft, each support element extending generally peripherally around the tubular graft, each support element including generally axial segments and generally peripheral segments. A plurality of first fasteners attach the plurality of support elements to the wall of the tubular graft, at least one generally axial segment being slidably engaged by each first fastener. A plurality of second fasteners also attach the plurality of support elements to the wall of the tubular graft, each second fastener substantially anchoring a generally peripheral segment of the respective support element to the wall of the tubular graft. The stent-graft also includes first and second stents on the first and second ends for substantially anchoring the respective ends within a body passage.

    摘要： An apparatus for sealing a puncture communicating with a blood vessel includes an inner member slidable within an outer member, and a balloon coupled to distal ends of the inner and outer members. A proximal end of the outer member includes a port for delivering fluid into the balloon, and a cylinder that communicates with the port. A piston coupled to the inner member is slidable and biased to move distally within the cylinder. The apparatus is introduced into the puncture until the collapsed balloon is disposed within the vessel. Fluid is introduced into the port, moving the inner member proximally to shorten the balloon as it expands. The balloon is withdrawn to seal the puncture, and a hydrogel is introduced into the puncture. Fluid is removed via the port, moving the inner member distally to extend the balloon as it collapses, and the apparatus is withdrawn.

    摘要： A stent includes a first flaring portion including first and second sets of cells that flare outwardly when the stent is expanded from a contracted to a flared condition, and a second main portion connected to the first flaring portion. During use, the stent is introduced into a main vessel in the contracted condition and positioned with the first portion adjacent an ostium. The first portion is flared, causing first struts of the first set of cells to move from an axial towards a radial and partial circumferential orientation and causing second struts of the second set of cells to move from an axial towards a radial orientation. The second portion resists expansion when the first portion is flared. The stent is expanded further such that the second portion expands within the branch body lumen, and the first and second struts move towards a more circumferential orientation.

    摘要翻译： 支架包括第一扩张部分，其包括当支架从收缩状态扩张到扩张状态时向外张开的第一组和第二组细胞，以及连接到第一扩张部分的第二主要部分。 在使用期间，支架在收缩状态下被引入主容器中，并且将第一部分定位成邻近口。 第一部分是喇叭形的，导致第一组细胞的第一支柱从轴向向径向和部分圆周取向移动，并使得第二组细胞的第二支柱从轴向向径向移动。 当第一部分展开时，第二部分抵抗扩张。 支架进一步膨胀，使得第二部分在分支体腔内扩张，并且第一和第二支柱向着更圆周方向移动。
