Method and articles for treating the sinus system
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.
1. A method of treating a sinus cavity of a subject using a balloon dilation catheter, the method comprising:
providing a balloon dilation catheter that includes
a handle,
an inner guide member fixed to the handle,
a balloon catheter comprising a balloon coupled to a shaft and slidably mounted on the inner guide member, and
a balloon advancement member configured to advance the balloon catheter over the inner guide member, wherein the inner guide member is configured such that it cannot rotate relative to the balloon catheter;
advancing the inner guide member to a desired location in a drainage pathway of the sinus cavity;
advancing the shaft over the inner guide member, wherein advancing the shaft places the balloon at the desired location; and
inflating the balloon.
2. The method of claim 1 , further comprising tracking 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 shaft defines at least a portion of an inflation lumen and a rider lumen, and wherein the inflation lumen is longer than the rider lumen.
6. The method of claim 5 , wherein a proximal portion of the inflation lumen wraps around the inner guide member in a helical shape.
7. The method of claim 1 , wherein a support member is secured to the shaft and the balloon advancement member is directly coupled to the support member.
8. The method of claim 1 , wherein the balloon dilation catheter further includes an inflation lumen port that is in fluid communication with an interior portion of the balloon and is static relative to the inner guide member when the shaft and balloon are advanced over the inner guide member.
9. The method of claim 1 , wherein a single hand of a user grasps the handle and is used to both advance the inner guide member to a desired location in a drainage pathway of the sinus cavity and advance the shaft and balloon over the inner guide member.
10. 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.
11. The method of claim 10 , wherein the shape is adjusted by replacing the inner guide member with a second inner guide member.
12. The method of claim 10 , wherein the shape is adjusted by manually bending the inner guide member.
13. 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.
14. The method of claim 1 , wherein the sinus cavity is a maxillary sinus cavity.
15. The method of claim 1 , wherein the sinus cavity is a sphenoid sinus cavity.
16. The method of claim 1 , wherein a user grasps the handle with a first hand and an endoscope with a second hand.
