STENT

摘要

For the better anchoring of a stent in its use area within a vessel, in the case of a stent expandable from a radially contracted introduction state into a radially expanded position state and having a body with material areas in the form of ribs and gaps in the form of free spaces between the ribs, in the radially expanded state at least one front end of the stent has a greater radial extension than the remaining main stent body with the material areas of the body being relatively thin and without material crossing points as in knitted and braided structures.
