## Abstract

Embodiments include medical devices comprising a handle assembly including a wire tensioner component and an adjustment knob, the adjustment knob configured to rotate about a longitudinal axis of the handle assembly; an elongate shaft coupled to the handle assembly, the elongate shaft defining a lumen and 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 configured to deflect independently of the deflectable section.

## Claims

### Claim 1

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 second wire reenters the lumen through a second opening, wherein the opening forms a first seal around the second wire and the second opening forms a second seal around the second wire, wherein the first seal and the second seal are configured to prevent fluid exchange through the opening and the second opening.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein the deflectable section of the elongate shaft includes at least one of the following: an electrode, a radiopaque marker band, a temperature sensor, and a multi-core fiber.

### Claim 3 (depends on 2)

The medical device of claim 2, wherein the adjustment knob configured to rotate about a longitudinal axis of the handle assembly.

### Claim 4 (depends on 2)

The medical device of claim 2, wherein the deflectable section includes at least one rigid section between two compressible joints.

### Claim 5 (depends on 2)

The medical device of claim 2, wherein the first and second wires are in physical contact with each other within the lumen at the distal end portion of the deflectable section.

### Claim 6 (depends on 2)

The medical device of claim 2, wherein the first and second wires are bonded to each other within the lumen at the distal end portion of the deflectable section.

### Claim 7 (depends on 2)

The medical device of claim 2, wherein the wire tensioner component is configured to provide a tension on the second wire in a neutral position, wherein the first wire is non-tensioned in the neutral position.

### Claim 8 (depends on 2)

The medical device of claim 2, wherein rotation of the adjustment knob in a first direction causes the deflectable section of the elongate shaft to deflect.

### Claim 9 (depends on 2)

The medical device of claim 2, wherein the deflectable extraluminal section of the second wire deflects in response to contact with a trailing edge of the esophagus of the subject.

### Claim 10

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.

### Claim 11 (depends on 10)

The deflectable member of claim 10, wherein the deflectable section of the elongate shaft includes at least one the following: an electrode, a radiopaque marker band, and a multi-core fiber.

### Claim 12 (depends on 10)

The deflectable member of claim 10, wherein the deflectable extraluminal section of the second wire includes at least one of the following: an electrode, a radiopaque marker band, a temperature sensor and a multi-core fiber.

### Claim 13 (depends on 10)

The deflectable member of claim 10, wherein the adjustment knob is independent from the wire tensioner component.

### Claim 14 (depends on 12)

The deflectable member of claim 12, wherein the temperature sensor is a thermocouple, a thermistor, or a core of a multi-core fiber.

### Claim 15 (depends on 10)

The deflectable member of claim 10, wherein the deflectable section includes at least one rigid section between two compressible joints.

### Claim 16 (depends on 10)

The deflectable member of claim 10, wherein the first and second wires are in physical contact with each other within the lumen at the distal end portion of the deflectable section, wherein the first and second wires independently carry a tensile and/or compressive load.

### Claim 17 (depends on 10)

The deflectable member of claim 10, wherein the first and second wires are bonded to each other within the lumen at the distal end portion of the deflectable section.

### Claim 18 (depends on 10)

The deflectable member of claim 10, wherein the deflectable extraluminal section of the second wire deflects in response to contact with a trailing edge of the esophagus of the subject.

### Claim 19

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.
