Abstract
A device for sensing aneurysmal pressure in a body cavity includes a housing including at least one chamber formed therein. A first fluid is positioned in a first portion of the chamber. A second fluid is positioned in a second portion of the chamber. A compressible fluid is positioned in the second portion of the chamber. A divider is positioned between the first and second fluids. A pressure membrane is in communication with the first portion of the chamber. The aneurysmal pressure is transmitted through the membrane and the first fluid to position the divider within the chamber. A method for determining aneurysmal pressure in a body cavity includes deploying a sensing device including radiopaque substance adjacent an aneurysm. The radiopaque substance is moved within the device in response to the aneurysmal pressure. The sensing device is imaged and pressure and/or relative pressure is read directly.
