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.
