## Abstract

A method for use with a balloon catheter device that includes a selectively bendable portion with a balloon disposed thereon, a control device for controlling bending of the selectively bendable portion, and a camera located at an end of a distal portion, includes inserting the distal portion into the nostril while the distal portion is straight; viewing an image provided by the camera; stopping insertion of the distal portion after the ethmoidal bulla is viewed in the image; articulating the distal portion in an upward direction to view the opening to the frontal sinus ostium or a downward direction to view the opening to the maxillary sinus ostium using the control device; inserting the distal portion into the frontal sinus ostium or the maxillary sinus ostium while the distal portion remains in the bent position; and inflating the balloon in the frontal sinus ostium or the maxillary sinus ostium.

## Claims

### Claim 1

A balloon catheter device comprising:
a hub;
an elongated body attached to the hub so as to extend from a distal portion of the hub, the elongated body comprising a selectively bendable portion with a balloon disposed thereon;
a camera located at an end of a distal portion of the balloon catheter device;
wherein the hub comprises:
an articulation control device comprising a slider that is operatively attached to the selectively bendable portion and located at an outer circumferential surface of the hub, the articulation control device being configured to control bending of the selectively bendable portion, wherein the camera moves along with movement of the selectively bendable portion by operating the articulation control device, and
a camera advancement control device comprising a slider that is operatively attached to the camera and located at the outer circumferential surface of the hub, the camera advancement control device being configured to control movement of the camera between a non-extended state and an extended state, wherein the camera is located at the end of the distal portion of the balloon catheter device in the non-extended state, wherein the camera is advanced beyond the end of the distal portion of the balloon catheter device in the extended state.

### Claim 2 (depends on 1)

The balloon catheter device of claim 1, wherein the selectively bendable portion is configured to bend only in a single plane.

### Claim 3 (depends on 2)

The balloon catheter device of claim 2, wherein the selectively bendable portion is configured to bend in a single direction from a non-bent position.

### Claim 4 (depends on 1)

The balloon catheter device of claim 1, wherein the camera is a CCD camera.

### Claim 5 (depends on 1)

The balloon catheter device of claim 1, wherein the camera comprises one of a (i) CMOS image sensor, (ii) an image fiber configured to transmit images via optical fibers, and (iii) an imaging system configured to transmit images via an objective lens and an optical system including a plurality of relay lenses.

### Claim 6 (depends on 1)

The balloon catheter device of claim 1, further comprising a light located at the end of the distal portion of the balloon catheter device.

### Claim 7 (depends on 6)

The balloon catheter device of claim 6, wherein the light is one of (i) an LED light, (ii) a halogen lamp, and (iii) a high-intensity discharge lamp.

### Claim 8 (depends on 1)

The balloon catheter device of claim 1, wherein the hub further comprises an image port configured to connect the camera to a display device.

### Claim 9 (depends on 1)

The balloon catheter device of claim 1, wherein the hub further comprises a pressure supply port configured to connect the balloon to a pressure supply device.

### Claim 10 (depends on 1)

The balloon catheter device of claim 1, further comprising:
a light located at the end of the distal portion of the balloon catheter device;
wherein the hub further comprises a light supply port configured to connect the light to a light power source device.
