Abstract
A method comprises providing a balloon catheter device; locating a balloon portion within a paranasal sinus ostium while the balloon portion is in the first position such that a distal end of the balloon portion is at a distal end of a paranasal sinus ostium; inflating the balloon portion while the balloon portion is located in the paranasal sinus ostium such that at least a portion of the paranasal sinus ostium is dilated; sliding the balloon portion back to a second position while leaving the distal end of a guide member at the distal end of the paranasal sinus ostium; and viewing an image provided by a camera to determine whether an entirety of the paranasal sinus ostium has been dilated.
Claims33
A method comprising:
- providing a balloon catheter device that comprises a balloon portion that is slidably disposed on a guide member, wherein the balloon portion is slidable from a first position with a distal end of the balloon portion at an extreme distal end of the guide member, to a second position with the distal end of the balloon portion at a predetermined length from the extreme distal end of the guide member, and wherein a camera is disposed at a distal end of the balloon portion such that the camera slides with the balloon portion;
- locating the balloon portion within a paranasal sinus ostium while the balloon portion is in the first position such that the distal end of the balloon portion is at a distal end of the paranasal sinus ostium;
- inflating the balloon portion while the balloon portion is located in the paranasal sinus ostium such that at least a portion of the paranasal sinus ostium is dilated;
- sliding the balloon portion back to the second position while leaving the distal end of the guide member at the distal end of the paranasal sinus ostium;
- and
- viewing an image provided by the camera to determine whether an entirety of the paranasal sinus ostium has been dilated.

A method comprising:
- providing a balloon catheter device that comprises a balloon portion and a camera, wherein the camera is slidably disposed in the balloon catheter device, and wherein the camera is slidable from a first position at an extreme distal end of the balloon portion, to a second position at a predetermined length from the extreme distal end of the balloon portion;
- locating the balloon portion within a paranasal sinus ostium while the camera is in the first position such that the end of the balloon portion and the camera are at a distal end of the paranasal sinus ostium;
- inflating the balloon portion while the balloon portion is located in the paranasal sinus ostium such that at least a portion of the paranasal sinus ostium is dilated;
- sliding the camera back to the second position while leaving the distal end of the balloon portion at the distal end of the paranasal sinus ostium;
- and
- viewing an image provided by the camera to determine whether an entirety of the paranasal sinus ostium has been dilated.
