Expandable stent for insertion into a body passage having a mesh structure of interconnecting portions ( 6 ) joined together by joining portions ( 5 ). The stent, when inserted into said body passage, is adapted to dissolve into smaller parts, wherein the joining portions dissolve faster than the interconnecting portions. In a preferred embodiment the joining portions are made from a first material and the interconnecting portions are made from a second material different from said first material, wherein the first material dissolves faster than said second material. |
