An expandable intraluminal endoprosthesis comprising a tubular member (1) a first diameter which permits intraluminal delivery of the member into a lumen of a body passageway, particularly a blood vessel. The tubular member (1) is capable of acquiring a second, expanded and deformed diameter upon the application from the interior of the tubular member of a radially outwardly extending force, which second diameter is variable and dependent on the amount of said force applied to the tubular member. Such a tubular member may be expanded and deformed to expand the lumen of the body passageway. According to the invention the wall of said tubular member is formed by a continuous filament (2) which is separated from a tube wall. Said filament (2) comprises a number of adjacent undulations which are staggered in a substantially helical configuration advancing around a longitudinal axis of the tubular body. A first helical turn (A-H) of said filament around said longitudinal axis of said tubular member is connected to an adjacent second such turn (A-H) of said filament by means of at least one connection element (31,32) which is an integral extension of said filament. <IMAGE> |
