摘要：
In some embodiments, an apparatus includes a first catheter movably disposed within a first lumen of a second catheter. The first catheter has a first occlusion member disposed at a distal end portion and the second catheter has a second occlusion member disposed at a distal end portion. A third catheter has a third occlusion member disposed at a distal end portion and is moveably disposable within a second lumen of the second catheter. The second catheter has a side port in fluid communication with the second lumen and the third catheter can be extended out of the second lumen through the side port. The first occlusion member, second occlusion member and third occlusion member can collectively isolate a target region including a portion of a first body lumen (e.g., a main vessel) and a portion of a second body lumen (e.g., a branch of the main vessel).
