OG exemplary drawing
 
1. An assembly for use with a vacuum system comprising:
a handle;
a first segment coupled to the handle;
a second segment connected to the first segment via an articulation pivot pin, the second segment defining a second segment proximal end coupled to the articulation pivot pin and a second segment distal end, the second segment defining a constant length and shape between the second segment distal end and the second segment proximal end;
an articulation drive cable that pivots the second segment about the first segment; and
an introducer including a soft outer tube sized to pass through a mouth or nasal passage into an esophagus, the soft outer tube defining a plurality of radial vacuum holes configured to apply a vacuum to an esophageal wall via the vacuum system.
