    摘要： A self-expanding stent includes a plurality of segments having a collapsed configuration and an expanded configuration. Preferably, the segments are unconnected to each other in at least the expanded configuration. The segments include restraining structures that temporarily restrain them from expansion until activated. This allows the user to position the desired number of segments at a treatment site and to deploy them simultaneously, thereby avoiding misalignment, overlap, and excessive spacing between segments. In preferred embodiments, multiple segmented stents of user-selectable length may be deployed at multiple locations in a single intervention.

    摘要： Some embodiments of the present disclosure are directed to endoluminal prostheses having one or more reinforced fenestrations therein. The one or more reinforced fenestrations can have improved sealing capabilities with respect to branch grafts deployed within the fenestrations, improved tear resistance and expandability, and improved pull-out resistance for branch grafts. In some embodiments, the endoluminal prosthesis can have a main graft body defining a flow lumen therethrough, a first opening passing through a wall of the main graft body, and a first support member supported by the main graft body and overlapping an edge of the first opening, the first support member being configured to at least increase the tear resistance of the main graft body adjacent to the first opening. The support member can be stitched or otherwise attached to the main graft adjacent to the fenestration.

    摘要： A fenestrated graft deployment system, with a delivery catheter having a catheter body, An endoluminal prosthesis having a main graft body, the main graft body having a lumen therethrough and a first opening laterally through a wall of the main graft body. A first guidewire prepositioned within the delivery catheter extending through at least a portion of the catheter body into a main lumen of the endoluminal prosthesis and through the first opening in the wall of the prosthesis when the delivery catheter is in a predeployed configuration. A first fenestration alignment device is configured to extend through at least a portion of the delivery catheter and is configured to be axially moveable relative to the first guidewire. The first fenestration alignment device has an end portion having an outside perimeter configured such that when an end portion of the fenestration alignment device moves toward the first opening of said main graft body the outside perimeter of the first opening is smaller than the outside perimeter of the first fenestration alignment device and prevents it from passing through the first opening and causes the main graft body adjacent to the first opening to move with the end of the first fenestration alignment device to act as alignment tool to allow an operator to align the first opening in the side of the endoluminal prosthesis with an ostium of a target branch vessel into which said first opening is to extend and act as a guide and seal for a subsequently delivered branch graft endoluminal prosthesis.

    摘要： Some embodiments relate to endoluminal prostheses having a first stent portion and a second stent portion, a main graft body comprising first, second, and third portions, the second portion having a cross-sectional size that is significantly larger than a cross-sectional size of the first or third portions, and also significantly larger than a cross-sectional size of the target vessel. In some embodiments, the first portion of the main graft body can be attached to the first stent portion and the third portion of the main graft body can be attached to the second stent portion. The prostheses can be configured such that the second portion of the main graft body is not directly attached to the first stent portion, the second stent portion, or any other internal support structure. In some embodiments, one or more openings can be formed in the second portion of the main graft body.
