A radially expandable support structure is presented, for keeping open lumina within a body, in particular a blood vessel, having a tube-shaped structure that has at least two partial structures, with a wall surface that extends between a first and a second end, which has several cut out areas, in particular, slits, which are essentially oriented parallel to the longitudinal axis of the tube-shaped structure. At least one of the partial structures ( ) extend without interruption in the axial direction generally from the first end to the second end of the tube-shaped structure. A first partial structure ( ) can be expanded at least in the radial direction and has at least one radial-expansion component. The individual radial expansion components ( ) are arranged as a helix or in a helix shape. A second partial structure ( ) is generally almost rigid in the axial direction. The two partial structures ( ) are arranged in such a way that during the radial expansion of the tube-shaped structure, the second partial structure ( ) receives the longitudinal axial forces that arise.

At least one partial structure (,) extends without interruption in the axial direction generally from the first end to the second end of the tube-shaped body. The first partial structure (,) can be expanded at least in the radial direction and has at least one radial-expansion component. Individual radial expansion components (,) are arranged as rings or in a ring shape, and the second partial structure (,) is almost rigid in the axial direction. The two partial structures (,) are arranged in such a way that during the radial expansion of the tube-shaped body, the second partial body (,) receives the longitudinal axial forces that arise.
