Abstract
A primary stent-graft is deployed into a primary vessel to exclude an aneurysm. To maintain perfusion to a branch vessel covered by the primary stent-graft, a gutter filling stent-graft is deployed in parallel to the primary stent-graft. The gutter filling stent-graft includes a balloon that is pressurized and inflated by the patient's own blood thereby sealing any gutters formed around the gutter filling stent-graft. By sealing the gutters, the chance of type I endoleaks, migrations, and overall failure to exclude the aneurysm is minimized.
Claims7
A graft assembly comprising:
- a primary stent-graft in parallel with a gutter filling stent-graft;
- the gutter filling stent-graft comprising:
- a main stent-graft comprising non-permeable graft material comprising an inner surface and an outer surface, the inner surface defining a lumen within the graft material;
- and
- a balloon coupled to the graft material at the outer surface, the balloon comprising:
- a base comprising permeable material, the base being perpendicular to a longitudinal axis of the main stent-graft;
- a balloon section coupled to the base, the balloon section comprising non-permeable material;
- and
- a single expansion member configured to expand the base, the single expansion member coupled to either an outer periphery of the base or an end of the balloon section which is coupled to the base, wherein the main stent-graft, the base, and the balloon section define an inflatable balloon sac of the balloon.
