Abstract
Abstract A device for implantation in a vessel or hollow organ lumen in a human or animal body, such as a self-expanding stent, a cava filter, an embolizing means or a supporting means, comprises a wire frame with a plurality of interconnected cells made of at least two separate wire sections which are intercrossing at cell junctions and form closed cells. At the cell junctions the wires are knot to form a geometrical locking of the cells so that the wire-shaped cell sides in respective cells are locked at the cell junctions when the wire frame is subjected to pressure acting radially inwards.
