Radially expandable vascular stent

Abstract

The invention relates to a radially expandable stent comprising a plurality of ring elements (2, 3, 27, 28) which are flexibly connected to each other by means of bending elements ((18, 20, 21) and which define the inventive stent (1) which is provided with a proximal end, a distal end and a longitudinal axis. The ring elements (2, 3, 27, 28) are arranged next to each other in a perpendicular position with respect to the longitudinal axis of the stent (1) and are respectively connected to each other by means of flexible bending elements (18, 20, 21). On the proximal and distal end of the stent (1), the ring elements (27,28) respectively located on the edge thereof are joined to each other by a pair of dumbbell-shaped bending elements (18). Ring elements (2,3) located in the centre thereof are joined to each other and respectively connected to the ring elements (28) on the edge thereof by two s-shaped bending elements (20,21). At least the bending elements (2,3) in the centre are embodied in the form of a zig-zag.
