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.
1. A method for measuring the size of a paranasal sinus ostium of a patient, the method comprising the steps of: (a) inserting a distal end portion of a paranasal sinus ostium measuring device internally into a patient, locating the paranasal sinus ostium to be measured with the distal end portion o
1. A method for measuring the size of a paranasal sinus ostium of a patient, the method comprising the steps of: (a) inserting a distal end portion of a paranasal sinus ostium measuring device internally into a patient, locating the paranasal sinus ostium to be measured with the distal end portion of the paranasal sinus ostium measuring device;(b) positioning the distal end portion of the paranasal sinus ostium measuring device within the patient to enable the target paranasal sinus ostium to be measured;(c) determining the paranasal sinus ostium size of the targeted paranasal sinus ostium by the paranasal sinus ostium measuring device, wherein the act of determining the paranasal sinus ostium size comprises determining the diameter of the paranasal sinus ostium by identifying a diameter of a portion of the distal end portion of the paranasal sinus ostium measuring device which contacts or closely approximates the walls of the paranasal sinus ostium;(d) withdrawing the paranasal sinus ostium measuring device from the targeted paranasal sinus ostium;(e) subsequent to withdrawing the paranasal sinus ostium measuring device, selecting a dilator device based upon the determined size of the targeted paranasal sinus ostium; and(f) dilating the targeted paranasal sinus ostium with the selected dilator device, wherein the act of dilating comprises remodeling bony structure that surrounds or is adjacent to the targeted paranasal sinus ostium. 2. The method of claim 1, wherein the distal end portion comprises an atraumatic tip. 3. The method of claim 2, wherein the atraumatic tip is substantially spherical. 4. The method of claim 2, wherein the distal end portion comprises a tapered mandrel extending proximally from the atraumatic tip. 5. The method of claim 3, wherein the spherical atraumatic tip is configured to fit within a paranasal ostium. 6. The method of claim 5, wherein the diameter of the spherical tip is in a range of about 0.5 mm to about 6 mm. 7. The method of claim 3, wherein the substantially spherical atraumatic tip comprises a radio-opaque marker. 8. The method of claim 7, further comprising indicia visible on the radio-opaque marker. 9. The method of claim 3, wherein the diameter of the substantially spherical tip ranges from about 0.5 mm to about 6 mm. 10. The device method of claim 1, wherein the distal end portion is flexible and malleable. 11. The device method of claim 1, wherein a proximal end portion of the paranasal sinus ostium measuring device has at least one portion that is flexible and malleable. 12. The method of claim 11, further comprising attaching a handpiece to the proximal end portion. 13. The method of claim 11, further comprising receiving at least the proximal end portion in a guide catheter. 14. The method of claim 1, further comprising a radio-opaque marking on the distal end portion. 15. The method of claim 14, further comprising indicia on the radio-opaque marking. 16. The method of claim 1, further comprising a plurality of radio-opaque markings on the distal end portion. 17. The method of claim 1, wherein the distal end portion comprises a telescoping portion. 18. The method of claim 17, wherein the telescoping portion comprises a central housing and telescoping features extendable transverse to a longitudinal axis of the distal end portion. 19. The method of claim 18, further comprising driving, via a handpiece with an actuator, the telescoping portion to retract and extend the telescoping features. 20. The method of claim 1, wherein the distal end portion has a lumen therethrough. 21. The method of claim 20, further comprising inserting a guidewire within the patient prior to inserting the measuring device, and wherein the distal end portion of the measuring device is inserted along the guidewire. 22. The method of claim 21 wherein the guidewire is an illuminating guidewire. 23. The method of claim 20, wherein the sinus ostium measuring device is preloaded onto a guidewire, the method comprising inserting the guidewire and preloaded paranasal sinus ostium measuring device within the patient. 24. The method of claim 1, wherein a proximal end portion of said paranasal sinus ostium measuring device is configured to connect to a handpiece. 25. The method of claim 1, wherein a proximal end portion of the paranasal sinus ostium measuring device is configured to connect to a guide catheter. 26. A method for measuring the size of a paranasal sinus ostium of a patient, the method comprising the steps of: (a) inserting a distal end portion of a paranasal sinus ostium measuring device internally into a patient, locating the paranasal sinus ostium to be measured with the distal end portion of the paranasal sinus ostium measuring device;(b) positioning the distal end portion of the paranasal sinus ostium measuring device within the patient to enable the target paranasal sinus ostium to be measured;(c) determining the paranasal sinus ostium size of the targeted paranasal sinus ostium by the paranasal sinus ostium measuring device, wherein the act of determining the paranasal sinus ostium size comprises determining the diameter of the paranasal sinus ostium by identifying a diameter of a portion of the distal end portion of the paranasal sinus ostium measuring device which contacts or closely approximates the walls of the paranasal sinus ostium, wherein the portion of the distal end portion of the paranasal sinus ostium measuring device which contacts the walls of the paranasal sinus ostium is a tapered mandrel including a proximal portion and a distal end, the distal end having a tip, the tip being narrower in width than the proximal portion;(d) withdrawing the paranasal sinus ostium measuring device from the targeted paranasal sinus ostium;(e) subsequent to withdrawing the paranasal sinus ostium measuring device, selecting a dilator device based upon the determined size of the targeted paranasal sinus ostium; and(f) dilating the targeted paranasal sinus ostium with the selected dilator device, wherein the act of dilating comprises remodeling bony structure that surrounds or is adjacent to the targeted paranasal sinus ostium. 27.
