Definitions
- all cell rings of the lattice structure can have at most 12, in particular at most 10, in particular at most 8, in particular at most 6, cells immediately adjacent in the circumferential direction of the lattice structure. It is possible for all cell rings to comprise at least 3 cells which are immediately adjacent to the lattice structure in a circumferential direction.
- Lattice structure achieved that is for the function of the lattice structure as a carrier for the Coverage is advantageous.
- high stability is achieved in the axial direction, ie in the direction of a longitudinal axis of the lattice structure, which improves the delivery of the medical device through a catheter.
- the lattice structure can have increased flexibility due to the closed cells, which leads to an improved radial force.
- the cover can be firmly connected to the lattice structure, in particular with a material bond.
- the cover is applied directly to the lattice structure.
- the process of electrospinning can take place directly on the lattice structure, so that a connection to the lattice structure is simultaneously established when the cover is formed.
- the cover can be integrally connected to the lattice structure.
- the cover can be connected to the lattice structure by an adhesive connection.
- the adhesive connection can be made by an adhesion promoter.
- the adhesion promoter can, for example
- Cross-sectional diameters have, for example, carotid arteries.
- the lattice structure can in principle be designed as a one-piece lattice structure. It is also possible for the lattice structure to be formed from wires intertwined with one another. To this extent, it is provided in preferred embodiments that the lattice elements form webs which are integrally coupled to one another by web connectors (one-piece lattice structure). Alternatively the grid elements can form wires that are intertwined
- the spacing of the further pores from one another can be at least 1-fold distance, in particular at least 1.5-fold spacing, in particular at least 2-fold spacing, in particular at least 2.5-fold spacing, in relation to the diameter of the further pores. At a 1-fold distance, this speaks to the diameter of another pore.
- Lattice structure follows a laser cutting process through the electrospinning process.
- Fig. 3 a scanning electron microscope image of a
- Lattice structure 10 has the maximum cross-sectional diameter, corresponds to the expanded state. In this state, the lattice structure 10 does not exert any radial forces.

Abstract
L'invention concerne un dispositif médical pour introduction dans un organe creux du corps, en particulier un stent, comprenant une structure de grille (10) composée d'éléments de grille (11, 12, 13, 14), pouvant être comprimée et étendue, qui présente au moins un anneau de cellules (34) fermé, lequel comprend au maximum 12, en particulier au maximum 10, plus particulièrement au maximum 8, plus particulièrement encore au maximum 6 cellules (30) directement adjacentes dans la direction circonférentielle de la structure de grille (10). L'invention est caractérisée en ce que la structure de grille (10) est munie au moins par tronçons d'une partie de recouvrement (40) composée d'une trame de fibres électrotissées, qui présente des pores (41) de taille irrégulière, la partie de recouvrement (40) présentant sur une surface de 100000 µm² au moins 10 pores qui présentent une taille d'au moins 15 µm².
