摘要： The invention relates to stents made of a material with an elongation at rupture of 30% or less and with a tubular base body which entirely or in parts comprises structural segments which are interconnected in longitudinal direction of the stents by means of transverse connectors and in which the structural segments comprise a zigzagging or undulating structure of a brace which is wrapped around the longitudinal axis of the stent. Due to the mechanical properties of the materials used, adaptation of the stent design is required. This is achieved in that in a turning region of the zigzagging or undulating structure the brace comprises a straight bending section aligned in circumferential direction.

摘要： The invention concerns a stent comprising a longitudinal axis (12) and a peripheral wall (14) which is formed at least over a part of the length of the stent (10) by a lattice-like carrier structure (24) which is open at two ends. The carrier structure includes at least one bar (16) extending helically around the longitudinal axis in such a way as to provide a helical primary shape (26) for the peripherally extending bar with more than one helical turn. Besides the helical primary shape (26) the bar has a zigzag-like or meander-shaped secondary shape (30) with reversal points and associated reversal portions (32), between which extend bar portions (34) of the peripherally extending bar with an extension component in the longitudinal direction of the stent. The carrier structure further includes connecting bars (40) which respectively bridge over a helical turn of the helical primary structure and which at their two longitudinal ends attach to the bar portions (34) of the helical primary shape between two respective adjacent reversal points.
