A medical device may include a plurality of branch members having moveable distal portions. The medical device also may include a first moveable member movably connected to the distal portion of one of the branch members at a first location along the branch member. The first moveable member may have first and second proximal portions extending from the first location and disposed within one or more lumens of one or more of the other branch members. The moveable distal portions of the plurality of branch members and the first moveable member may form a first snare movable between a collapsed configuration and an expanded configuration.
