Abstract
An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed frame cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament-shaped frame material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one frame cell directly into the frame cell following in the longitudinal direction. The stent can be expanded from a radially compressed state into a state having a larger diameter. In the expanded state of the stent, the pressure transmitting frame material in several of the frame cells (2) forms a heart-like or arrowhead-like shape with two interconnected shorter cell sides (5) positioned opposite to and interconnected with two mutually converging longer cell sides (3).
