1. A method for advancing a flexible device into a paranasal sinus, the method comprising:
- (a) inserting a guide catheter into a head of a patient, wherein the flexible device is either preloaded into the guide catheter or advanced into the guide catheter during or after insertion of the guide catheter into the patient'"'"'s head;
(b) generating a suction force proximally through the guide catheter, around the flexible device, and within the head of the patient, via a suction source attached to the guide catheter, wherein the step of generating the suction force is performed while the guide catheter is being advanced into the head of the patient; and
(c) advancing the flexible device out of a distal end of the guide catheter into the paranasal sinus.

16. A method for advancing a flexible device into a paranasal sinus, wherein the flexible device includes a balloon dilation catheter and a guidewire, the method comprising:
-
(a) inserting a guide catheter into a head of a patient, wherein the flexible device is either preloaded into the guide catheter or advanced into the guide catheter during or after insertion of the guide catheter into the patient'"'"'s head; (b) generating a suction force proximally through the guide catheter, around the flexible device, and within the head of the patient, via a suction source attached to the guide catheter, wherein the step of generating the suction force is performed while the guide catheter is being advanced into the head of the patient; (c) suctioning debris from the head of the patient; (d) advancing the guidewire out of a distal end of the guide catheter into the paranasal sinus before the balloon dilation catheter is advanced; (e) advancing the balloon dilation catheter out of a distal end of the guide catheter into the paranasal sinus; (f) expanding a balloon of the balloon dilation catheter to an expanded state in order to prevent suction via the suction force through the guide catheter and to the head of the patient; and (g) dilating an opening of the paranasal sinus with the balloon dilation catheter. - View Dependent Claims (17, 18, 19)

20. A method for advancing a flexible device into a paranasal sinus, wherein the flexible device includes a balloon dilation catheter, the method comprising:
-
(a) inserting a guide catheter into a head of a patient, wherein the flexible device is either preloaded into the guide catheter or advanced into the guide catheter during or after insertion of the guide catheter into the patient'"'"'s head; (b) generating a suction force proximally through the guide catheter, around the flexible device, and within the head of the patient, via a suction source attached to the guide catheter, wherein the step of generating the suction force is performed while the guide catheter is being advanced into the head of the patient; (c) opening a pathway to a maxillary sinus ostium behind an uncinate process with a distal end of the guide catheter; (d) introducing the guide catheter along the pathway to the maxillary sinus ostium; (e) advancing the flexible device out of a distal end of the guide catheter into the paranasal sinus toward the maxillary sinus ostium; and (f) dilating the maxillary sinus ostium with the balloon dilation catheter.
