Abstract
A vascular prosthesis with an impregnation including at least one sealing material in the prosthesis wall and/or with a coating including at least one sealing material on the outer surface of the prosthesis, wherein the prosthesis, when subjected to a force of 1 N acting perpendicularly with respect to the outer surface of the prosthesis, is deformed such that the external diameter of the prosthesis decreases, in the direction of the acting force, by 60 to 100% in relation to the original external diameter.

1-21. (canceled)
A method of producing a vascular prosthesis comprising spraying a vascular prosthesis having an inner surface, an outer surface and a wall with a liquid containing at least one sealing material, wherein the liquid is sprayed onto the outer surface at a pressure of 0.01 to 1.5 bar to generate a sealing impregnation in the wall, and/or is sprayed onto the outer surface at a pressure of 5.0 to 50 bar to generate a sealing coating on the outer surface.
A vascular prosthesis with an impregnation comprising at least one sealing material in a wall of the prosthesis and/or with a coating comprising at least one sealing material on an outer surface of the prosthesis, wherein the prosthesis, when subjected to a force of 1 N acting perpendicularly with respect to the outer surface, is deformed such that an external diameter of the prosthesis decreases in the direction of the acting force by 60 to 100% in relation to an original external diameter.
