1. A tubular shaped device comprising:
- a. a first outer wall;
b. a second inner wall having a smaller diameter than the first outer wall;
c. a fused juncture of the first and second wall that creates fluid impermeable seals and fluid communicating passages within an interstitial space between the first and second wall;
d. a valve to convey fluid into the interstitial space.

Abstract
A method and apparatus for repair of stenotic and aneurysmic vessels utilizing in situ deployment of an inflatable tubular shaped device (1) having a longitudinally oriented annulus (17). When inflated, the size and rigidity of the device (1) is increased, thereby providing supplemental strength to the vessel wall and a lumen (8) for the passage of fluid.

14. A method for repair of vessel walls comprising the steps of:
-
a. inserting a sealable two walled tubular shaped device within the vessel lumen utilizing a catheter having a fluid conveying means in communication to a value assessing an interstitial space between the walls of the device;
b. maneuvering the device to a selected location within the vessel;
c. inserting fluid through a controllable value within the device and into interstitial space between the two walls of the device;
d. continuing the addition of fluid to deploy the device in a radial direction sufficient that the one wall contacts the vessel wall and an annular space is created along the longitudinal length of the device;
e. withdrawing the catheter.
