Abstract:
1. A support prosthesis for vessels or intracorporeal lumens with a tubular casing having an expandable meandering pattern forming one or more support rings and which is formed by a filament having successive bending curves that are bent alternatively in opposite directions and that are to be stretched on expansion of the support prosthesis by reducing the curvature of the bending curves, wherein all of said bending curves have a respective narrowing in which the cross sectional area of the filament is at its minimum, and wherein the cross-sectional area of the filament tapers within each of said bending curves continuously toward each narrowing, and wherein narrowings of each of said bending curves are arranged in a circumferential direction of the support prosthesis with respect to a longitudinal axis of said prosthesis exclusively on the inlet side or exclusively on the outlet side of the bending curves.
