Abstract
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.
