    摘要： A catheter with a self-expanding stent of a permeable mesh of stiff intersecting fibers is provided. A tubular outer catheter shaft holds the stent under tension at its distal end and from which the stent can be released for placement. A displaceable inner catheter inside the tubular outer catheter shaft supports the stent axially at its proximal end. In order to release the stent, the outer catheter shaft is retracted with respect to the inner catheter. A process for producing this catheter is also described. The stent is secured by gripping it at its proximal end in such a way that it forms a permeable mesh cone that expands automatically together with the stent and has a radius that increases gradually to the radius of the relaxed stent. The stent is securely anchored on the inner catheter with the help of the mesh cone.

    摘要： The stent having a flexible self-expandable braided tubular wall having a proximal segment having an outer diameter, and a distal segment having an outer diameter smaller than the outer diameter of the proximal segment. An intermediate segment is formed between the proximal and distal segments, which forms a truncated cone of which the base is forming the proximal end of the intermediate segment and of which the top is forming the distal end of the intermediate segment. A covering layer is arranged within the tubular wall.

    摘要： The endoprosthesis is inserted under tension in a recess of a flexible inner catheter and secured by means of a tube-shaped outer catheter. To release the endoprosthesis into a vessel, the outer catheter is pushed back over the recess. The recess is formed by a connector piece that connects a tip to a piece of tubing of the inner catheter. The inner catheter can be designed with a smaller outer diameter in the region of the recess than was previously the case with at least the same flexibility and resistance to buckling.
