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.
Claims45
A sinus ostium measurement device, comprising:
- a distal end portion and a proximal end portion, at least a portion of said distal end portion being configurable to a known measurement size for positioning in a sinus ostium for measurement of the ostium.
A method for measuring the size of a sinus ostium of a patient, said method comprising the steps of:
- inserting a distal end portion of a sinus ostium measuring device internally into a patient,
- locating the sinus ostium to be measured with the distal end portion of the sinus ostium measuring device,
- positioning the distal end portion of the sinus ostium measuring device within the patient to enable the target sinus ostium to be measured;
- and
- determining the sinus ostium size of the targeted sinus ostium by the sinus ostium measuring device.
A kit for measuring a target sinus ostium, comprising:
- a plurality of sinus ostium measuring devices, said sinus ostium measuring devices having a distal end portion and a proximal end portion, said distal end portions having an atraumatic tip which is substantially spherical, and
- said substantially spherical tip of each of said plurality of sinus ostium measuring devices has a diameter which is different from the other said plurality of sinus ostium measuring devices.
