Abstract
A stent assembly, delivery system and method of manufacture therefor. A stent assembly includes a compact stent. A dissolvable material impregnates the stent in liquid form. In its cured, solid form, the material contains the stent in its compact form. When the stent is positioned in a vessel, the temperature and liquids in the vessel dissolve the material thereby to release the stent for positioning in a final configuration. The expansion of the stent then allows removal of the delivery system.
