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.
Claims20
A graft assembly comprising:
- a gutter filling stent-graft comprising:
- a main stent-graft comprising 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;
- a balloon section coupled to the base;
- and
- an expansion member configured to expand the base.

A graft assembly comprising:
- a gutter filling stent-graft comprising:
- a main stent-graft comprising:
- a proximal section comprising non-permeable material;
- a distal section comprising the non-permeable material;
- a middle section coupled to the proximal section and the distal section, the middle section being configured to allow fluid to pass therethrough;
- a balloon coupled to the proximal section and the distal section, the balloon disposed around the middle section.
3 more elements
A method comprising:
- deploying a gutter filling stent-graft in parallel with a primary stent-graft into a primary vessel, wherein a gutter exists around the gutter filling stent-graft;
- and
- configuring fluid to flow into a balloon of the gutter filling stent-graft to expand the balloon into the gutter to seal the gutter.
