A stent graft assembly having a tubular body and a constraining patch attached to the interior surface of the tubular body. The constraining patch delineates a small passageway close to the inner surface of the tubular body. A cannula may extend through the passageway.
Claims20
A stent graft assembly comprising:
- a tubular body having a first open end, a second open end, a main lumen between the first open end and the second open end, and an inner surface surrounding the main lumen;
- a patch disposed in the main lumen and attached to the inner surface and defining a longitudinally extending passageway between the inner surface and the patch, the patch having a first unattached end and a second unattached end;
- wherein the passageway is in fluid communication with the main lumen through the first unattached end and the second unattached end;
- wherein neither unattached end is in communication with an exterior of the graft, and
- wherein the patch is configured to temporarily constrain a portion of a medical instrument within the passageway.
2 more elements
A stent graft assembly comprising:
- a tubular body having a main lumen and an inner surface surrounding the main lumen;
- a patch disposed in the main lumen, the patch comprising a piece of material attached to the inner surface that forms a passageway that extends at least longitudinally along the patch and has a first open end and a second open end;
- wherein the passageway has a first configuration where a portion of the patch extends away from the inner surface and the passageway is open, and a second configuration where the patch lays flat against the inner surface and the passageway is closed.
A stent graft assembly comprising:
- a tubular body having a main lumen and an inner surface surrounding the main lumen;
- a patch disposed in the main lumen and attached to the inner surface;
- the patch forming an constraining tube having a longitudinal constraining lumen extending therethrough, wherein the constraining tube has first and second open ends and wherein neither open end is exposed to an exterior of the tubular body.
