Abstract

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.

First claim

What is claimed is:

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, and
a 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.

2. The method of claim 1 , further comprising tracking the movement of the inner guide member into a frontal recess using an image guided surgery system.

3. The method of claim 2 , wherein the image guided surgery system comprises a CT guidance system.

4. The method of claim 1 , wherein the inner guide member includes a lumen and, prior to inflating the balloon, a guide wire is inserted into the lumen and advanced until a distal portion of the guide wire extends from a distal end of the inner guide member.

5. The method of claim 1 , wherein the handle is fixed to the inner guide member.

6. The method of claim 1 , further including adjusting a shape of the inner guide member prior to advancing the inner guide member to the desired location.

7. The method of claim 6 , wherein the shape is adjusted by replacing the inner guide member with a second inner guide member.

8. The method of claim 6 , wherein the shape is adjusted by manually bending the inner guide member.

9. The method of claim 1 , wherein the inner guide member defines a lumen and the method further includes coupling the lumen to an aspiration source and aspirating the sinus cavity.

10. The method of claim 1 , wherein the sinus cavity is a maxillary sinus cavity.

11. The method of claim 1 , wherein the sinus cavity is a sphenoid sinus cavity.

12. The method of claim 1 , wherein a user grasps the handle with a first hand and the lighted instrument with a second hand.

13. The method of claim 1 , wherein the inner guide member includes a lumen and, prior to inflating the balloon, the lighted instrument is advanced distally inside the lumen and illuminates at least a portion of the sinus cavity.
