## Abstract

A movable bougie tip device includes a tip section having a tip, a holder, and a recoiled wire and a bougie section having a bougie, a silk thread, and a slide button located at a first end thereof. The slide button adjusts an angle of the tip relative to the bougie. The silk thread is disposed within a body of the bougie and extends through an outer surface of the tip from the body of the bougie through an opening and protrudes out the tip. The holder holds the silk thread at a distal end of the tip section. The tip bends at an angle ranging from 30° to 90° relative to the bougie, and the recoiled wire prevents kinking of the tip.

## Claims

### Claim 1

A movable tip bougie device, comprising:
a tip section and a bougie section;
wherein the bougie section comprises a bougie body, a silk thread, and a slide button located at a first end of the bougie section;
wherein the slide button is configured to mechanically adjust an angle of a tip disposed on a distal end of the tip section relative to the bougie body by action of the slide button through the silk thread; and
wherein a first end of the silk thread is connected to the slide button and a second end of the silk thread is connected to the tip;
the tip section includes the tip, a holder, and a recoiled wire;
wherein the silk thread extends through an outer surface of the tip and through an opening of the bougie body; and
the holder is configured to hold the silk thread at the distal end of the tip section; and
the recoiled wire is helically coiled around the tip; and
the tip section is connected to the bougie section through a hinge and is configured to move backwards toward the bougie section on retraction of the slide button and forward on pushing the slide button forward.

### Claim 2 (depends on 1)

The device of claim 1, wherein the tip is fabricated of polyvinyl chloride (PVC).

### Claim 3 (depends on 1)

The device of claim 1, wherein the slide button has a top surface and a bottom surface and a flat circumferential edge between the top surface and bottom surface, wherein the flat circumferential edge includes a notch to engage with the bougie body.

### Claim 4 (depends on 3)

The device of claim 3, wherein the body of the bougie has at least seven grooves in which the slide button slides into an individual groove to adjust the angle of the tip by at least 10°.

### Claim 5 (depends on 1)

The device of claim 1, wherein the recoiled wire is fabricated of stainless steel.

### Claim 6 (depends on 1)

The device of claim 1, wherein the recoiled wire is spirally wound around an interior of the tip.

### Claim 7 (depends on 1)

The device of claim 1, wherein the tip section further includes a clipper to align the silk thread through the tip.

### Claim 8 (depends on 1)

The device of claim 1, wherein the silk thread is a fiber.

### Claim 9 (depends on 1)

The device of claim 1, wherein a length of a slit is from 5% to 40% of an entire length of the bougie body.

### Claim 10 (depends on 1)

The device of claim 1, wherein the tip is configured to bend from 60° to 90° relative to a longitudinal axis of the bougie body when the slide button slides towards the first end of the bougie section.

### Claim 11 (depends on 1)

The device of claim 1, wherein the tip is configured to bend from 30° to 50° relative to a longitudinal axis of the bougie body when the slide button slides towards the first end of the bougie section.

### Claim 12 (depends on 1)

The device of claim 1, wherein the bougie body is substantially cylindrical and a ratio of a length of the bougie body to a width of the bougie body is from 5:1 to 20:1.

### Claim 13 (depends on 1)

The device of claim 1, wherein the recoiled wire is helically coiled against an interior surface of the tip, so that the recoiled wire runs from a first end of the interior of the tip to a second end of the interior of the tip.

### Claim 14 (depends on 1)

The device of claim 1, wherein the first end of the bougie body is substantially elliptical.

### Claim 15 (depends on 1)

The device of claim 1, wherein the silk thread runs through the bougie body so that a longitudinal axis of the silk thread is underneath and parallel to a longitudinal axis of the slide button.

### Claim 16 (depends on 1)

The device of claim 1, wherein the tip includes one of a coude tip, a reverse coude tip, or a bullet tip.

### Claim 17 (depends on 4)

The device of claim 4, wherein a second groove situated between a first groove and a third groove is equidistant from both the first groove and the third groove.
