A device for narrowing the passage through surrounding vascular wall tissue, such as a ring prosthesis for reducing the size of the passage of a heart valve, includes a ring shaped element which is elastically contractile under influence of a resilient force for contracting the ring shaped element from an expanded, wide condition to a narrow condition to narrow the passage. A method of narrowing the passage through surrounding vascular wall tissue using such a device is also disclosed.
