Abstract
A stent for the transluminal implantation in hollow organs, in particular in blood vessels, ureters, oesophagi or gall tracts, is described, having a substantially tubular body which has a plurality of apertures which are each bounded by elongated boundary elements. In each case at least two boundary elements bounding the same aperture and arranged alongside one another in the circumferential direction are extended beyond the end of the aperture and form a unitary detection element. The detection element has a greater width in the circumferential direction of the stent than each of the boundary elements.

A stent for the transluminal implantation in hollow organs comprising:
- a substantially tubular body having a plurality of apertures respectively bounded by elongate boundary elements,
- wherein at least two boundary elements, arranged adjacent one another in the peripheral direction of the stent, bound one aperture of said plurality of apertures and are configured to extend beyond an end of said one aperture thereby forming a unitary detection element,
- each unitary detection element being substantially contiguous and integral in both the longitudinal and circumferential directions of said stent,
- whereby the effective area of the unitary detection element material has a greater width in the circumferential direction than each of the boundary elements and also has a longitudinal length that is longer than the width of each of the boundary elements, thereby providing a way of positively locating said stent by x-ray.
A stent for the transluminal implantation in hollow organs comprising:
- an essentially tubular body, expandable from a compressed state having a first cross-sectional diameter into an expanded state having an enlarged second cross-sectional diameter,
- wherein a wall of said tubular body has a plurality of apertures enabling said expansion,
- wherein said plurality of apertures are configured both in the compressed state and in the expanded state as apertures which are extended in the longitudinal direction and in the circumferential direction of the stent;
- wherein connection locations of thickened design are provided between two of said apertures arranged adjacent to one another in the longitudinal direction of the stent;
- and
- wherein said apertures are areal and provide a means of reinforcing the stability of the connection locations, and
- wherein a thickness of said wall of said tubular body is essentially equal to a width of elongated boundary elements limiting said apertures in the circumferential direction of the stent.
