Abstract
The present invention relates to a stent device comprising a sleeve formed with a plurality of compactable spring ring elements arranged along its length, the sleeve having compacted and expanded states. Each said ring element has an undulating profile at the surface of the sleeve so that adjacent ring elements at least partially overlap along the longitudinal extent of the device, the ring elements being compactable against their natural resilience to reduce the outer diameter of the sleeve for allowing housing of the compacted stent device in a frangible sheath, with adjacent ring elements being inter-coupled so as to substantially maintain their axial spacing between the compacted and expanded states.
