A stent is provided with braided filaments. First and second filaments (12, 14) are braided with each other and extend spirally around the stent wall in opposite directions. One or more third filaments (16) are braided with the first filaments (12) and extends spirally around the stent wall only in the direction of the second filaments (14). The third filament (16) is stiffer than the first and second filaments (12, 14), and there are fewer third filaments (16) than the first and second filaments (12, 14).
