A vascular aneurysm-treating stent arrangement (10) having a proximal end (22) and a distal end (24), the stent being formed of a differentially expandable material, wherein the distal end (24) is deformably expandable to a cone shape (50) . A deformable enclosed chamber (50) is arranged on the distal end (24) of the stent (20) and nests within the aneurysm (62) . A different embolic agent is introduced into the aneurysm and into the chamber. |
