A DEVICE FOR IMPLANTATION IN A VESSEL OR HOLLOW ORGAN LUMEN

摘要

A device for implantation in a vessel or hollow organ lumen in a human or animal body, the device comprising a wire frame with a plurality of interconnected cells made of at least two separate wire sections (4, 5) which are intercrossing at cell junctions (6) and form closed cells. The wire frame includes a combination of knot cell junctions of different types, which junctions (6) are knot to form a geometrical locking of the cells when the wire frame is subjected to pressure acting radially inwards.
