1. A method of preventing leakage between a prosthetic valve and a vessel wall comprising:

  • deploying a self-expanding mesh cuff having at least two-ply in a vessel prior to implanting the prosthetic valve, said mesh cuff including a center body portion and two end portions on either side of the center body portion;

    allowing the end portions to expand and form a seal against a wall of the vessel wall while the center body portion of said cuff forms an open lumen;

    implanting the prosthetic valve within said open lumen after the step of allowing the end portions to expand;

    wherein at least one of said end portions mushrooms when expanded such that a gap is created between the plies of the end portions, thereby creating a funnel for guiding a delivery catheter into said open lumen in said cuff, and allowing an outer ply to conform against native tissue while an inner ply creates said funnel;

    and wherein allowing the end portions to expand causes at least one of said end portions to fold.
