Abstract:
A tubular stent comprising a series of at least three circumferentially arranged circular closed loop elements (1) cut from wire or from flat or tubular material, each of said loop elements having only one major longitudinal axis (2) having a predetermined length and one minor circumferential axis (3) having a predetermined length wherein said loops are aligned with their respective major axis in a parallel manner and their minor axis perpendicular to the longitudinal axis of the stent, each of said closed loop elements being connected to each circumferentially adjacent closed loop element at a discrete point (4) on the loop at the midportion of each major axis between adjacent loops so that each closed loop element has two opposing connecting points, the loop elements arranged circumferentially around a cylindrical member (5) such that the series of closed loop elements form a tubular segment having a proximal and a distal end and a tubular diameter.
