Abstract

A system includes an inner filling structure around a stent-structure and an outer filling structure around the inner filling structure. The inner filling structure can be configured to produce a proximal seal with a first portion of an artery at a proximal end and a distal seal with a second portion of an artery at a distal end when the inner filling structure is in an inflacted state. The outer filling structure can have an inner surface surrounding at least a portion of the inner filling structure. The outer filling structure can be configured to be inflatable to occupy a space within an aneurysm at a lower pressure than a pressure in the inner filling structure.
