Esophageal deviator

A deflectable member of a medical device for displacing an esophagus of a subject during a medical procedure, the deflectable member comprising:

• an elongate shaft, an outermost wall of the elongate shaft defining a lumen, the elongate shaft including a deflectable section, wherein the deflectable section is configured to shift between a neutral position and a deflected position through activation of a first wire via an adjustment knob;
• and
• a second wire having a deflectable extraluminal section where the second wire exits the lumen of the elongate shaft through an opening, the deflectable extraluminal section extending between proximal and distal end portions of the deflectable section,
• wherein the wire tensioner component elongates under a tensile load,
• wherein the deflectable extraluminal section is configured to deflect independently of the deflectable section.

A medical device for displacing an esophagus of a subject during a medical procedure, the medical device comprising:

• a handle assembly including a wire tensioner component and an adjustment knob;
• an elongate shaft coupled to the handle assembly, an outermost wall of the elongate shaft defining a lumen, the elongate shaft including a deflectable section;
• a first wire coupled to the adjustment knob and extending from the adjustment knob through the lumen to at least a distal end portion of the deflectable section;
• and
• a second wire coupled to the wire tensioner component and extending from the wire tensioner component to at least the distal end portion of the deflectable section, the second wire having a deflectable extraluminal section where the second wire exits the lumen of the elongate shaft through an opening, the deflectable extraluminal section configured to deflect independently of the deflectable section, wherein the wire tensioner component elongates under a tensile load, wherein the wire tensioner component includes a spring, and wherein the spring mechanically couples the second wire to the handle assembly.
