For transluminal implantation in hollow organs, such as blood vessels, urethra etc., a stent comprises a tubular body (1) which can be put in an expanded state and has apertures (3,4) in both longitudinal and circumferential directions to ensure expansion. Each aperture has at least one section (3',3",3"') which is positioned at an angle to the longitudinal axis in both compressed and expanded state. The apertures form slot-like openings with several, partic. three sections which are inclined to the longitudinal axis. The apertures may be zig-zag shaped, Z-shaped, S-shaped or partic. sinusoidal. The body is pref. of memory metal, partic. Nitinol, and/or body-compatible plastic, partic. PE, PA, or PUR elastomer. |
