Systems and methods for endovascular aneurysm treatment

A method for treating an aneurysm in a patient, the method comprising:

• positioning at least one double-walled filling structure across the aneurysm;
• filling the at least one filling structure with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow across the aneurysm, wherein the blood flow directly contacts a surface of the inner wall, and wherein the at least one filling structure substantially fills the aneurysm when filled with the filling medium;
• supporting the tubular lumen with a support structure during filling and/or after the filling of the at least one double-walled filling structure with the filling medium;
• and
• monitoring aneurysm repair by monitoring at least a first pressure measured at the interior of the at least one filling structure with a pressure monitoring system during filling and/or after filling of the at least one filling structure;
• and
• wherein monitoring aneurysm repair further comprises monitoring a second pressure between an outer surface of the at least one filling structure and a wall of the aneurysm with the pressure monitoring system during filling and/or after filling of the at least one filling structure.
