ENDOVASCULAR DEVICES FOR EXPLOITING INTRAMURAL SPACE

The present invention relates to an apparatus for facilitating treatment via a vascular wall defining a true lumen containing an occlusion therein, the apparatus comprising an orienting device including a distal shaft defining a central lumen and having an outer wall, wherein the orienting device includes an orienting element that is coupled to the distal shaft, the orienting element comprising a first inflatable member and a second inflatable member configured to orient the orienting device upon being inflated, wherein the first inflatable member extends from the distal shaft in a first direction and the second inflatable member extends from the distal shaft in a second direction substantially opposite the first direction, characterised in that the orienting element is configured to assume a folded shape when the first and second inflatable members are deflated.
