Methods for treating sinus ostia using balloon catheter devices having a bendable balloon portion
First Claim
1. A method comprising:
- providing 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,a camera located at an end of a distal portion of the balloon catheter device such that the camera moves along with movement of the selectively bendable portion by operating the control device, anda camera advancement control 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;
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.

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.
