Method and articles for treating the sinus system

摘要

A method of treating a sinus cavity of a subject includes advancing a distal portion of a light source through a drainage pathway of a sinus cavity and into the sinus cavity and visually observing a transdermal light emitted from the light source. A distal portion of a substantially rigid inner guide member of a balloon dilation catheter is advanced into the drainage pathway, the balloon dilation catheter including a movable shaft including a balloon that is slidably mounted on the substantially rigid inner guide member. The movable shaft and balloon are advanced distally over the substantially rigid inner guide member to place a portion of the balloon in the drainage pathway whereby the balloon is inflated.

主权项

1. A method of treating a sinus cavity of a subject using a balloon dilation catheter, the method comprising:
providing a lighted instrument and illuminating at least a portion of the sinus cavity; providing a balloon dilation catheter that includes
a handle having a stationary inflation port located in a proximal end of the handle,an inner guide member secured to the handle and extending distally from a distal end of the handle a pre-determined distance,a balloon catheter slidably mounted on the inner guide member and including an inflatable balloon coupled to the stationary inflation port with an inflation lumen,a shaft coupled to the balloon, wherein the shaft defines at least a portion of the inflation lumen and a rider lumen, and wherein the inflation lumen is longer than the rider lumen and wherein a proximal portion of the inflation lumen wraps around the inner guide member in a helical shape, anda balloon advancement member disposed in a slot formed in the handle, the balloon advancement member configured to advance the balloon catheter over the inner guide member; advancing the inner guide member to a desired location in a drainage pathway of the sinus cavity; advancing the balloon over the inner guide member with the balloon advancement member, wherein advancing the balloon places the balloon at the desired location; and inflating the balloon with an inflation device coupled to the inflation port.
