A prosthetic device for sustaining a vessel or hollow organ lumen (a stent) having a tubular wire frame ( ) with rows of elongate cells ( ) each having a larger axis and a smaller axis. The cells are arranged with the larger axis in the circumferential direction of the frame ( ) and the smaller axis parallel to the axial direction thereof. Each cell is formed by two U-shaped wire sections, and in a plane perpendicular to the longitudinal axis one of the branches of the U-shaped wire sections in one row form together a closed ring shape ( ) which provides the frame ( ) with large radial stiffness. In the axial direction the frame ( ) has only low stiffness so that it easily conforms to the vascular wall even if this deforms due to external loads. The interconnection between the cells ( ) may be flexible.
