This Application is a continuation of U.S. patent application Ser. No. 13/644,538, filed on Oct. 4, 2012, now U.S. Pat. No. 8,882,795, which is a continuation of U.S. patent application Ser. No. 13/116,712 filed on May 26, 2011, which is a continuation of U.S. application Ser. No. 12/479,521, filed on Jun. 5, 2009, now U.S. Pat. No. 8,282,667. The above-noted Applications are incorporated by reference as if set forth fully herein.
FIGS. 3A and 3B illustrate, respectively, side and cross-sectional views of the balloon dilation catheter 10 with the advancer knob 32 and thus balloon 36 in the distal position. Thus, unlike the configurations of FIGS. 2A and 2B, the advancer knob 32 is located at or near the distal end 26 of the handle 12. Advancement of the advancer knob 32 also slides the shaft 30 and attached balloon 36 in a distal direction (arrow A in FIG. 3A) along the inner guide member 14. The balloon 36 thus is positioned at or adjacent to the distal end 20 of the inner guide member 14. The balloon dilation catheter 10 may be designed such that the advancer knob 32 may be positioned at either the proximal or distal extremes as illustrated in FIGS. 2A, 2B, 3A, 3B.
Alternatively, the advancer knob 32 may be positioned somewhere in between the two extremes. For example, the optimal position of the balloon 36 may be accomplished by sliding the advancer knob 32 some fraction (e.g., ¾) of the full distance of the slot 42.
1. A method of treating an outflow tract that opens into a nasal passage of a subject using a balloon dilation catheter, the method comprising:
a substantially rigid inner guide member extending longitudinally from the handle,
a movable shaft coupled to a balloon and slidably mounted on the substantially rigid inner guide member, and
a balloon advancement member slidably disposed within the slot and configured to advance the shaft and the balloon in a distal direction over the substantially rigid inner guide member;
advancing the substantially rigid inner guide member into the outflow tract of the subject via the nasal passageway;
advancing the balloon advancement member in the distal direction while keeping the handle static relative to the outflow tract, wherein advancing the balloon advancement member places the balloon at a desired location in the outflow tract; and
5. The method of claim 1, wherein the substantially rigid inner guide member includes a lumen, the lumen being coupled to an aspiration source configured to aspirate the outflow tract.
6. The method of claim 1, wherein, prior to inflation of the balloon, the substantially rigid inner guide member includes a lumen and a guide wire is inserted into the lumen and advanced until a distal portion extends from a distal end of the substantially rigid inner guide member.
7. The method of claim 6, further comprising re-positioning the substantially rigid inner guide member based at least in part on the location of the distal portion of the guide wire.
8. The method of claim 1, wherein the handle comprises a distal stop configured to prevent continued distal advancement of the balloon.
9. The method of claim 1, wherein the handle comprises an inflation port that is attached to a proximal end of the handle.
10. The method of claim 9, wherein the balloon advancement member is advanced from a first proximal position to a second distal position and wherein the first proximal position and the second distal position are both distal with respect to the inflation port.
11. The method of claim 1, wherein the balloon is inflated to a pressure within the range of about 3 atmospheres to about 12 atmospheres.
12. The method of claim 1, wherein the balloon is inflated, deflated, and inflated a plurality of times.
13. The method of claim 1, wherein the outflow tract is an outflow tract of a sinus cavity.
15. The method of claim 13, wherein the sinus cavity is a maxillary sinus cavity.
16. The method of claim 13, wherein the sinus cavity is a frontal sinus cavity.
17. The method of claim 1, further comprising tracking the movement of the substantially rigid inner guide member into the outflow tract using an image guided surgery system.
18. The method of claim 17, wherein the image guided surgery system comprises a CT guidance system.
