Abstract
The invention concerns a stent comprising a longitudinal axis () and a peripheral wall () which is formed at least over a part of the length of the stent () by a lattice-like carrier structure () which is open at two ends. The carrier structure includes at least one bar () extending helically around the longitudinal axis in such a way as to provide a helical primary shape () for the peripherally extending bar with more than one helical turn. Besides the helical primary shape () the bar has a zigzag-like or meander-shaped secondary shape () with reversal points and associated reversal portions (), between which extend bar portions () of the peripherally extending bar with an extension component in the longitudinal direction of the stent. The carrier structure further includes connecting bars () which respectively bridge over a helical turn of the helical primary structure and which at their two longitudinal ends attach to the bar portions () of the helical primary shape between two respective adjacent reversal points.
