1. An intraluminal stent comprising:
- a generally elongate tubular body formed of an elongate helically wound wire, the wire being formed into successive waves along the length of the wire, the waves being arranged in non-overlapping longitudinally spaced succession along the length of said tube, the longitudinal spacing of the helical windings being less than twice the amplitude of the wave.

Abstract
An intraluminally implantable stent is formed of helically wound wire. The stent has a generally elongate tubular configuration and is radially expandable after implantation in a body vessel. The wire includes successively formed waves along the length of the wire. When helically wound into a tube, the waves are longitudinally nested along the longitudinal extent of the stent so as to form a densely compacted wire configuration. After radial expansion the stent maintains high radial compressive strength and wire density to retard tissue ingrowth.

8. A radially expandable generally tubular endoluminal implantable prosthesis comprising:
a wire which is wound in a helical configuration to define a generally elongate tubular body, the wire including successively formed waves along the length of said wire, each wire wave being non-overlappingly nested within the wave formed longitudinally thereadjacent. - View Dependent Claims (9, 10, 11, 12, 13, 15, 16, 17, 18)

14. An intraluminal stent comprising:
-
an elongate tubular body formed of a single wound wire;
said wire having a wave-like pattern defining a plurality of waves formed along the length of said wire, each said wave defining a leg segment between wave peaks, each leg segment being of a length different from the next adjacent leg segment.
