Abstract:
1. A coupling device for a prosthesis comprising inner and outer coupling elements arranged concentrically one within the other, the coupling elements have a contracted condition and an expanded condition; and a substantially non-porous membrane covering at least the outer coupling element; wherein the outer coupling element is self-expandable; the inner and outer coupling elements being able to expand to different diameters and to be spaced from one another when expanded, such that in use the outer coupling element expands to abut a vessel wall, while the inner coupling element extends inwardly thereof to couple to one or more prosthetic modules, wherein the outer coupling and inner coupling are radially spaced from one another by a first distance in the contracted configuration and by a second distance in the expanded configuration, and where the second distance is greater than the first distance.
