<p>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 comprises a substantially continuous structure (2) of mutually staggered undulations. Said structure has been separated from a tube wall and exhibits at least one pattern which advances substantially helically along a longitudinal axis of the tubular body. Connection elements within the structure connect adjacent undulations to each other. These connection elements are an integral extension of the undulations thereby interconnected. <IMAGE></p> |
