摘要

The invention pertains to a stent to be set inside a body vessel, having a flexible support structure imbedded in a hollow-cylindrical casing made of a plastic that has limited elasticity, at least at body temperature. The support structure consists of two zigzag-shaped wires that run parallel to the longitudinal axis of the casing, mutually offset at the perimeter of the casing. Each wire (1) has at least three segments (2, 3, 4), of which the middle segment (3) forms an acute angle ( alpha , beta ) with each of the two adjoining segments (2, 4). If radial pressure from without is applied to the stent at point B, then point B moves downward in the focal plane in a circular movement as angulation point C moves upward in a countermovement. As a result the two movements counterbalance each other. The stent remains stable over its entire length X.
