Abstract
The present invention refers to a tubular support prostheses (stent) for vessels or intercorporeal lumina comprising at least two adjacently arranged expandable support rings connected to one another on at least one joint, said support rings being formed by a filament wound in a meander-like manner to form several arcs of curvature. The expansion behavior of such a support prosthesis is to be improved. For this purpose at least one arc of curvature of a first support ring and an arc of curvature of an adjacent second support ring overlap laterally, whereby the joint in the overlapping portion is formed.
