1. A stent deployment apparatus comprising:
a body, the body including:
a bore defined therein,
a restriction disposed in the bore,
at least one aperture extending in a longitudinal direction of the restriction;
a window disposed within a side of the body;
a stent device having a proximal end and a distal end defining a stent axis, the stent device disposed within the bore, the stent device including:
a sleeve formed with a plurality of compactable spring ring elements arranged along its length, the sleeve having compacted and expanded states;
wherein each said ring element has an undulating profile at a surface of the sleeve so that adjacent ring elements at least partially overlap along a longitudinal extent of the device,
the ring elements being compactable against their natural resilience to reduce an 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; and
a sheath material disposed over at least a portion of the stent device, wherein the restriction is configured to obstruct travel of the stent device but allow passage of the sheath material, with at least a portion of the sheath material passing through the window within the side of the body thereby exiting the body perpendicularly to the stent axis.
