Stent in form of a tube like grid structure which consists of at least one sequence (i.e., one tubular segment) of closed loop or ring elements (1) which are connected with each other at at least one connecting point (4) per loop (loop contact point) wherein either the opposing ends of each sequence are circumferentially connected or one sequence is helically wrapped around the longitudinal axis of the stent. The closed loop elements are ellipses or have a half moon or bananalike shape.
