Abstract
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.
Claims15
A stent graft, comprising:
- a hollow stent graft body having a lumen extending from one end of the hollow stent graft body to a second end of the hollow stent graft body;
- an expandable reservoir provided within the lumen of the hollow stent graft body, the expandable reservoir being covered with a separation layer on a side of the expandable reservoir exposed to the lumen, the expandable reservoir configured to swell when exposed to blood within the lumen, the separation layer initially configured to prevent the expandable reservoir from being exposed to the blood flowing through the lumen;
- and
- the separation layer being configured to selectively expose the expandable reservoir to the blood to cause the expandable reservoir to swell, wherein swelling of the expandable reservoir reduces a cross-sectional area of the lumen.
A stent graft, comprising:
- a hollow stent graft body having a lumen extending from a first end of the hollow stent graft body to a second end of the hollow stent graft body;
- and
- an expandable reservoir provided within the lumen of the hollow stent graft body, the expandable reservoir configured to swell when exposed to blood within the lumen, but covered with a separation layer on a side of the expandable reservoir facing the lumen to prevent the expandable reservoir from being exposed to the blood flowing through the lumen, wherein the separation layer is configured to selectively expose the expandable reservoir to the blood, wherein swelling of the expandable reservoir reduces a cross-sectional area of the lumen.
