Abstract
A guide catheter for use in treating sinuses, the catheter including a catheter shaft configured to provide suction about a balloon catheter and a distal portion shaped for navigating body anatomy. In one embodiment, the guide catheter includes a valve for sealing the balloon catheter and a vent for controlling suction.
Claims21
-34. (canceled)
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 head of the patient;
- (b) moving a distal end of the guide catheter within the head of the patient;
- (c) 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 flexible device is disposed within the guide catheter;
- and
- (d) advancing the flexible device out of the distal end of the guide catheter into the paranasal sinus.
A method for advancing a flexible device into a paranasal sinus, the method comprising:
- (a) inserting a distal end of 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 via an instrument port during or after insertion of the guide catheter into the head of the patient;
- (b) moving the distal end of the guide catheter within the head of the patient to position the distal end of the guide catheter adjacent to the paranasal sinus;
- (c) generating a suction force proximally through the guide catheter, around the flexible device, and within the head of the patient via a suction source coupled to a suction port;
- and
- (d) advancing the flexible device out of the distal end of the guide catheter within the paranasal sinus while the step of generating the suction force is being performed.

- (b) advancing a distal end of the guide catheter within the head of the patient and further positioning the distal end of the guide catheter adjacent to the paranasal sinus;
- (c) 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 distal end of the guide catheter is being advanced or positioned within the head of the patient;
