Methods and devices for ostium measurement
First Claim
1. A method for measuring the size of and treating a paranasal sinus ostium of a patient, said method comprising the steps of:
- advancing a guidewire through a targeted paranasal sinus ostium in a patient;
inserting a paranasal sinus ostium measuring device into the patient over the guidewire, wherein the measuring device comprises;
an elongate, at least partially rigid shaft having a proximal end and a distal end;
an enlarged distal end portion at the distal end of the shaft; and
at least one preformed bend in the shaft;
locating the targeted paranasal sinus ostium with the distal end portion of the paranasal sinus ostium measuring device;
positioning the distal end portion of the paranasal sinus ostium measuring device at least partially within or through the targeted paranasal sinus ostium;
determining a diameter of the targeted paranasal sinus ostium using the paranasal sinus ostium measuring device;
withdrawing the paranasal sinus ostium measuring device from within or through the targeted paranasal sinus ostium;
subsequent to withdrawing the paranasal sinus ostium measuring device, selecting a balloon catheter based upon the diameter of the targeted paranasal sinus ostium such that a balloon of the balloon catheter, when inflated within the ostium, fractures, moves or remodels bony structures that surround or are adjacent to the targeted paranasal sinus ostium; and
intra-operatively treating the targeted paranasal sinus ostium with the selected balloon catheter.

Abstract
Devices and methods for accurately determining the size of an ostium of a patient and in particular sinus ostium. Methods for measuring a target ostium comprise inserting the distal end portion of an ostium measuring device into a patient, locating the target ostium with the measuring device, positioning the distal end portion of the measuring device appropriately adjacent to or into the target ostium and determining the diameter(s) of the target ostium by comparing the length, diameter and/or the circumference of the portion of the distal end portion of the measuring device adjacent to or within the target ostium.
