Claim:
1. An intravascular implant configured to be compressed for delivery and to self-expand when deployed, comprising: a self-expandable tubular body having a proximal end, a distal end and a central lumen extending therethrough, the body being metal and comprising a plurality of metal struts; the self-expandable tubular body comprising a zig-zag distal-most ring and a zig zag proximal-most ring, the self-expandable tubular body forming only a single cell column which comprises at least one open cell that is formed between internally facing struts of the distal-most and proximal-most rings, at least one bridge comprising a first V bend and a second V bend and a radiopaque marker positioned between the first and second V bends; wherein the tubular body having a compression force curve being a measure of the amount of radial force required to compress the tubular body throughout a range of outer diameters, and having an expansion force curve being a measure of the amount of radial force exerted by the tubular body when the tubular body radially self-expands throughout a range of outer diameters which range is equal to or greater than 3 mm, the compression force is greater than the expansion force within the range, and the difference in radial force between the compression force curve and the expansion force curve is no more than 2 Newtons (N) at any point in the range of outer diameters.
