The present invention provides for an expandable stent (1) for use in an artery or other vessel of a human body which forms a plurality of spaced apart generally circular rings (2). The stent structure (1) maintains patency of a vessel within which the stent (1) is inserted and is formed by a plurality of closed and generally circular rings (2) where the plane of each ring (2) is substantially parallel to the plane of an adjacent ring (2). The rings (2) have a common longitudinal axis generally perpendicular to the plane of each ring (2) with the longitudinal axis passing through the geometric center of each of the rings (2). A plurality of elongated wire structures forming longitudinals (4T, 4B, 4R, 4L) are fixedly secured to the rings (2) and extend in a direction generally parallel to the longitudinal axis of the rings (2). The stent (1) formed of the generally circular rings (2) optimizes hoop strength and minimizes elastic recoil of a vessel into which the stent (1) is inserted.
