A tubular prosthesis (10) is provided which includes a tubular (12) member and an outer covering sealed (14) to portions of the tubular member, with a pocket (16) being defined therebetween. A filling agent (18), preferably a substantially incompressible agent, is disposed in the pocket so as to cause portions of the outer covering to expand from the tubular member. As an endovascular prosthesis, the filled pocket can be used as a seal against the wall of a blood vessel to prevent Type I endoleaks. |
