Abstract

Devices, kits, and methods of treatment are described. More particularly, methods of treating tissue of a passage wall defining a bodily passage, such as a sinus cavity, airway, or sinus passage are described. An exemplary method utilizes an elongate member having an elongate member proximal end, elongate member distal end, and an elongate member body that defines a curve.

First claim

What is claimed is:

1. A delivery device, comprising:
a housing having a housing proximal end, a housing distal end, and a housing body defining a housing lumen;
a cannula having a cannula proximal end, a cannula distal end, and a cannula body defining a cannula lumen, the cannula attached to the housing such that the housing lumen and the cannula lumen are in communication;
a pusher having a pusher proximal end, a pusher distal end slidably disposed within the housing lumen, and a pusher body that defines a pusher lumen, the pusher moveable between a pusher first configuration and a pusher second configuration; and
a catheter attached to the pusher and having at least a portion disposed within the cannula lumen, the catheter comprising an elongate member and a balloon, the elongate member having an elongate member proximal end, an elongate member distal end, and an elongate member body defining an inflation lumen in communication with the pusher lumen and an elongate member curve, the balloon disposed on the elongate member and having a wall defining a balloon chamber in communication with the inflation lumen, the balloon moveable between a first deflated configuration and a second inflated configuration as fluid is moved into and out of the balloon chamber, the elongate member adapted to move between a first substantially straight configuration in which the portion of the elongate member that defines the elongate member curve is substantially straight when disposed within the cannula lumen and a second curved configuration when the portion of the elongate member that defines the elongate member curve is free of the cannula lumen.

2. The delivery device of claim 1 , wherein the elongate member has an elongate member first axis and an elongate member second axis, the elongate member first axis extending along a portion of the elongate member body disposed proximal to the elongate member curve, the elongate member second axis extending through the elongate member first axis and the elongate member distal end; and
wherein the elongate member second axis is disposed at an angle to the elongate member first axis.

3. The delivery device of claim 2 , wherein the elongate member second axis is disposed at an angle selected from the group consisting of a substantially 45 degree angle, a substantially 90 degree angle, and a substantially 135 degree angle to the elongate member first axis.

4. The delivery device of claim 2 , wherein the elongate member second axis is disposed at a substantially 90 degree angle to the elongate member first axis.

5. The delivery device of claim 2 , wherein the elongate member curve is defined between the elongate member proximal end and the elongate member distal end.

6. The delivery device of claim 2 , wherein the elongate member curve is defined from a location between the elongate member proximal end and the elongate member distal end to the elongate member distal end.

7. The delivery device of claim 6 , wherein the elongate member second axis is disposed at an angle selected from the group consisting of a substantially 45 degree angle, a substantially 90 degree angle, and a substantially 135 degree angle to the elongate member first axis.

8. The delivery device of claim 6 , wherein the elongate member second axis is disposed at a substantially 90 degree angle to the elongate member first axis.

9. The delivery device of claim 2 , wherein the elongate member curve is defined between the balloon and the elongate member distal end.

10. The delivery device of claim 9 , wherein the elongate member second axis is disposed at an angle selected from the group consisting of a substantially 45 degree angle, a substantially 90 degree angle, and a substantially 135 degree angle to the elongate member first axis.

11. The delivery device of claim 10 , wherein the elongate member second axis is disposed at a substantially 90 degree angle to the elongate member first axis.

12. The delivery device of claim 9 , wherein the elongate member second axis is disposed at a substantially 90 degree angle to the elongate member first axis.

13. The delivery device of claim 2 , wherein the balloon has a balloon proximal end and a balloon distal end; and
wherein the elongate member curve is defined between the balloon distal end and the elongate member distal end.

14. The delivery device of claim 13 , wherein the elongate member second axis is disposed at an angle selected from the group consisting of a substantially 45 degree angle, a substantially 90 degree angle, and a substantially 135 degree angle to the elongate member first axis.

15. The delivery device of claim 2 , wherein a portion of the elongate member contacts the cannula body when the elongate member is in the first substantially straight configuration.

16. A delivery device, comprising:
a housing having a housing proximal end, a housing distal end, and a housing body defining a housing lumen;
a cannula having a cannula proximal end, a cannula distal end, and a cannula body defining a cannula lumen, the cannula attached to the housing such that the housing lumen and the cannula lumen are in communication;
a pusher having a pusher proximal end, a pusher distal end slidably disposed within the housing lumen, and a pusher body that defines a pusher lumen, the pusher moveable between a pusher first configuration and a pusher second configuration; and
a catheter attached to the pusher and having at least a portion disposed within the cannula lumen, the catheter comprising an elongate member and a balloon, the elongate member having an elongate member proximal end, an elongate member distal end, and an elongate member body defining an inflation lumen in communication with the pusher lumen and an elongate member curve, the balloon disposed on the elongate member and having a wall defining a balloon chamber in communication with the inflation lumen, the balloon moveable between a first deflated configuration and a second inflated configuration as fluid is moved into and out of the balloon chamber, the elongate member adapted to move between a first substantially straight configuration in which the portion of the elongate member that defines the elongate member curve is substantially straight and a second curved configuration;
wherein the elongate member curve is defined between the balloon and the elongate member distal end; and
wherein the elongate member is biased to the second curved configuration.

17. The delivery device of claim 16 , wherein the elongate member curve is defined between the balloon distal end and the elongate member distal end.

18. The delivery device of claim 16 , wherein the elongate member has an elongate member first axis and an elongate member second axis, the elongate member first axis extending along a portion of the elongate member body disposed proximal to the elongate member curve, the elongate member second axis extending through the elongate member first axis and the elongate member distal end; and
wherein the elongate member second axis is disposed at an angle to the elongate member first axis.

19. The delivery device of claim 16 , wherein the elongate member second axis is disposed at a substantially 90 degree angle to the elongate member first axis.

20. A delivery device, comprising:
a housing having a housing proximal end, a housing distal end, and a housing body defining a housing lumen;
a cannula having a cannula proximal end, a cannula distal end, and a cannula body defining a cannula lumen, the cannula attached to the hou
