    Abstract: A branch prosthesis configured for placement in a branch vessel includes an expandable tubular body portion, an expandable annular flange attached to a proximal end of the body portion, and a sealing sleeve proximally extending from the annular flange. The sealing sleeve is adapted to deform to a generally straight cylindrical hollow shape during implantation. When deployed, the sealing sleeve rolls up to a tightly-wound coil that bears against the annular flange. When used in conjunction with a main prosthesis having a side opening and deployed within in a main vessel, the annular flange of the branch prosthesis engages an outer surface of the main prosthesis around a perimeter of the side opening and the sealing sleeve engages an inner surface of the main prosthesis around the perimeter of the side opening to form a fluid-tight seal between the main prosthesis and the branch prosthesis.

    Abstract: A tubular prosthesis comprises a tubular graft; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the first group of apexes being pivotally attached to the tubular graft so as to form a plurality of circumferentially arranged hinges about which the stent can pivot so that the second group of apexes can move between a position where they are inside the tubular graft and a position where they are outside the tubular graft. In one embodiment a tubular prosthesis comprises a tubular graft having a first end margin, a second end margin and a central portion therebetween; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the undulating stent being secured to the tubular graft in a manner such that it can be inverted to extend generally in the same direction as the tubular graft with one end thereof forming an end of said tubular prosthesis and pointing away from the central portion of the tubular graft.

    Abstract: A tubular synthetic endoluminal graft having at least one radiopaque ink marker pattern to radiographically delineate the surface of the graft cloth. The radiopaque ink marker includes a matrix of ink dots defining an annular band about a circumference of the graft. The endoluminal graft including at least one stent attached to the graft. The at least one stent may overlap or be positioned adjacent the radiopaque ink marker. The radiopaque ink marker may be utilized to facilitate creation of a fenestration in the side wall of the graft in situ to perfuse a side branch vessel.

    Abstract: A method includes deploying a bloused stent-graft into a main vessel such that a bloused section of the bloused stent-graft covers a branch vessel emanating from the main vessel. The bloused section includes loose graft cloth. A pressure differential between the main vessel and the branch vessel causes the bloused section to be forced into an ostium of the branch vessel creating a pocket aligned with the branch vessel. A distal tip of a puncture device is located in the pocket and thus aligned with the branch vessel. An outward force is applied to the puncture device to cause the distal tip of the puncture device to fenestrate the bloused section thus creating a collateral opening in the bloused section precisely aligned with the branch vessel.
