Abstract
A stent is formed in a tube like grid structure which consists of at least one sequence (i.e., one tubular segment) of closed loop elements which are connected to each other at at least one connecting point per loop (the loop contact point) wherein either the opposing ends of each sequence are circumferentially connected or one sequence is helically wrapped around the longitudinal axis of the stent.
Claims14
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.
A stent made of a series of closed circular loop elements (1) cut from wire or from tubular or flat material, each of said closed loop elements (1) having a major longitudinal and a minor circumferential axis (2 and 3) each of a predetermined length and wherein said loop elements, (1) are connected to each other at a discrete point (4) on the loops at the midpoint of the major longitudinal axis between adjacent loops to form a chain of closed loop elements and wherein the series of loop elements is arranged helically around a cylindrical member such that the series of loop elements forms a tubular segment with a proximal and distal end and having a tubular diameter.
