摘要:
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.

摘要:
A system and method for treating a blood vessel that is at least partially obstructed by an occlusion which divides the lumen into a proximal lumen segment and a distal lumen segment. The system includes an orienting catheter having an orientation element positionable in an intrawall space of the vessel and an occlusion catheter having an occlusion balloon inflatable in the proximal lumen segment so as to isolate a target volume including the intrawall space. The pressure inside the target volume is reduced to a pressure below the pressure of the distal lumen segment so that the intima presses against the orienting element of the orienting catheter. A distal end of a reentry device may be advanced from the orienting catheter through the intima and into the distal lumen segment.
