Abstract

Abstract An occlusion system treats an aneurysm in a parent vessel. The parent vessel defines a lumen that has a lumen wall. The aneurysm has a neck in communication with the lumen. The occlusion system includes a stent configured for deployment in the parent vessel. The stent has at least a first portion and a second portion. The first portion is permeable to blood flow and is arranged such that, when the stent is deployed, the first portion is spaced from the neck of the aneurysm. The second portion is less permeable to blood flow than the first portion and is arranged such that, when the stent is deployed, the second portion overlies the neck of the aneurysm.
