First Claim
Patent Images
1. An isolation device for isolating an aneurysm located near an intersection of a trunk of a blood vessel and a plurality of branches, the isolation device comprising:
- a body having a first end, a second end and a lumen therethrough along a longitudinal axis, wherein the body is configured for positioning within the intersection so that the aneurysm is substantially aligned with the longitudinal axis;
an occluder disposed across the lumen so as to allow blood flow into the first end along the longitudinal axis and to divert flow away from the longitudinal axis so as to isolate the aneurysm.

Abstract
Device, systems and methods are provided to isolate aneurysms, particularly at bifurcations, while maintaining adequate blood flow through nearby vessels. These devices are deliverable to a desired target area and maintain position in a desired orientation so as to occlude flow in some aspect while allowing flow in others. In addition, devices, systems and methods are provided to occlude blood vessels, such as endoleaks, to improve the isolation of aneurysms.
