The present invention relates to a stent graft, comprising: a hollow stent graft body having a lumen extending from one end of the stent graft body to the respective other end of the stent graft body, an expandable reservoir provided on an interior of the stent graft body, the expandable reservoir being covered with a separation layer on a side of the expandable reservoir facing the lumen, the expandable reservoir being arranged so as to swell when exposed to blood, the separation layer being arranged to prevent the expandable reservoir from being exposed to blood flowing through the lumen, the separation layer being arranged so that it can selectively expose the expandable reservoir to blood to cause the expandable reservoir to swell.

A stent graft configured to facilitate the placement of a secondary stent is provided and a method thereof. The stent graft can include an elongated body with a frame structure, a lumen, and apertures at both ends of the elongated body. The frame structure can be covered by a graft material. At least one station can be located in the graft material. The at least one station has a perimeter defined by a ring structure connected to the graft material and an aperture bounded by the perimeter. The aperture can be covered by graft material. The at least one station can be fenestrated to facilitate placement of a secondary stent.

A method of detecting the presence or absence of a sealant applied to a textile graft includes the steps of: providing a textile graft having a first surface and an opposed second surface; providing a water soluble masking agent; applying the water soluble masking agent to at least a portion of the first surface of the textile graft; providing a sealant solution; providing a visual indicator; applying the water insoluble sealing agent and the visual indicator to the second surface of the textile graft; and removing the water soluble masking agent after the step of applying sealing solution. The second surface has visual indication of the visual indicator and the first surface is substantially free of visual indication of the visual indicator. An implantable textile graft includes the selectively applied visual indicator.

Described are stent grafts with at least on branch and mandrels used to form the stent grafts. Methods of making and using them are also described.

A stent graft, including multiple wavy rings. The stent graft includes, in a circumferential direction, a region A and a region B connected to the region A. Each wavy ring includes a first wavy section located in the region A, and a second wavy section located in the region B. The wave included angle of the first wavy section is about 70°-120°; the ratio of the wave height of the first wavy section to the spacing between adjacent first wavy sections is 1/4-3; the wave included angle of the second wavy section is 30°-60°, the ratio of the wave height of the second wavy section to the spacing between adjacent second wavy sections is 1/4-3/2, and the ratio of the wave height of the first wavy section to the wave height of the second wavy section is greater than or equal to 1/3 and less than 1.
