Abstract

Medical devices, methods and kits are described. An exemplary medical device comprises a catheter that has a catheter wall and defines a catheter lumen, a bend, and a coil disposed distal to the bend. The catheter defines one or more apertures that extend through the catheter wall and are in communication with the catheter lumen.

First claim

What is claimed is:

1. A medical device for treating a sinus cavity, the medical device comprising:
a cannula defining a lumen;
a catheter disposed within the lumen defined by the cannula, the catheter having a catheter wall defining a plurality of apertures and adapted to move between a first substantially straight configuration when disposed within the lumen defined by the cannula and a second configuration in which the catheter defines a bend and a coil when the catheter is free of the lumen defined by the cannula;
a lubricious coating disposed on the catheter; and
a pusher slidably disposed in the lumen defined by the cannula and adapted to transfer axial movement to the catheter to move the catheter from the first configuration to the second configuration.

2. The medical device of claim 1 , wherein each aperture of the plurality of apertures is disposed on the coil when the catheter is in the second configuration.

3. The medical device of claim 1 , wherein the coil has an outwardly facing side and an inwardly facing side when the catheter is in the second configuration; and
wherein a first set of apertures of the plurality of apertures is disposed on the outwardly facing side of the coil and a second set of apertures of the plurality of apertures is disposed on the inwardly facing side of the coil when the catheter is in the second configuration.

4. The medical device of claim 1 , wherein the catheter further comprises a marker disposed at the bend.

5. A medical device for treating a sinus cavity, the medical device comprising:
a cannula defining a lumen;
a catheter disposed within the lumen defined by the cannula, the catheter adapted to move between a first substantially straight configuration when disposed within the lumen defined by the cannula and a second configuration in which the catheter defines a bend and a coil when the catheter is free of the lumen defined by the cannula;
a coating disposed on the catheter; and
a pusher slidably disposed in the lumen defined by the cannula and adapted to transfer axial movement to the catheter to move the catheter from the first configuration to the second configuration.

6. The medical device of claim 5 , wherein the catheter has a catheter wall defining a plurality of apertures; and
wherein each aperture of the plurality of apertures is disposed on the coil when the catheter is in the second configuration.

7. The medical device of claim 5 , wherein the catheter has a catheter wall defining a plurality of apertures;
wherein the coil has an outwardly facing side and an inwardly feeing side when the catheter is in the second configuration; and
wherein a first set of apertures of the plurality of apertures is disposed on the outwardly facing side of the coil and a second set of apertures of the plurality of apertures is disposed on the inwardly facing side of the coil when the catheter is in the second configuration.

8. The medical device of claim 5 , wherein the catheter further comprises a marker disposed at the bend.

9. A method of deploying a medical device into a sinus cavity, the method composing:
advancing a medical device into a nasal passage such that a portion of the medical device is disposed within the nasal passage, the medical device comprising:
a cannula defining a lumen;
a catheter disposed within the lumen defined by the cannula, the catheter adapted to move between a first substantially straight configuration when disposed within the lumen defined by the cannula and a second configuration in which the catheter defines a bend and a coil when the catheter is free of the lumen defined by the cannula; and
a pusher slidably disposed in the lumen defined by the cannula and adapted to transfer axial movement to the catheter to move the catheter from the first configuration to the second configuration;

navigating the cannula toward a point of treatment;
applying a distal force on the pusher such that the catheter is advanced into said sinus cavity and the catheter moves from the first, substantially straight configuration to the second configuration; and
withdrawing the cannula and pusher from the nasal passage.

10. The method of claim 9 , further comprising withdrawing the catheter from said sinus cavity and the nasal passage.

11. The method of claim 9 , further comprising trimming the catheter.

12. The method of claim 9 , wherein the catheter defines a lumen;
further comprising introducing medication into the lumen defined by the catheter and said sinus cavity.

13. The method of claim 12 , further comprising allowing for an interval of time to pass;
wherein allowing for an interval of time to pass is completed subsequent to introducing medication into the lumen defined by the catheter and said sinus cavity; and
repeating introducing medication into the lumen defined by the catheter and said sinus cavity subsequent to allowing for an interval of time to pass.

14. The method of claim 9 , wherein the catheter defines a catheter lumen;
wherein the catheter has a wall defining a plurality of apertures, each aperture of the plurality of apertures extending through the wall and in communication with the lumen defined by the catheter; and
wherein each aperture of the plurality of apertures is disposed on the coil when the catheter is in the second configuration.

15. The method of claim 9 , wherein the catheter has a catheter wall defining a plurality of apertures;
wherein the coil has an outwardly facing side and an inwardly facing side when the catheter is in the second configuration; and
wherein a first set of apertures of the plurality of apertures is disposed on the outwardly facing side of the coil and a second set of apertures of the plurality of apertures is disposed on the inwardly facing side of the coil when the catheter is in the second configuration.

16. The method of claim 9 , wherein the catheter further comprises a marker disposed at the bend.

17. A kit comprising:
a delivery system comprising a cannula and a pusher, the cannula defining a lumen, the pusher slidably disposed in the lumen defined by the cannula; and
a catheter adapted to move between a first substantially straight configuration when disposed within the lumen defined by the cannula and a second configuration in which the catheter defines a bend and a coil when the catheter is free of the lumen defined by the cannula;
wherein the pusher is adapted to transfer axial movement to the catheter to move the catheter from the first configuration to the second configuration.

18. The kit of claim 17 , wherein the catheter comprises a plurality of catheters, each catheter of the plurality of catheters adapted to move between a first substantially straight configuration when disposed within the lumen defined by the cannula and a second configuration in which the catheter defines a bend and a coil when the catheter is free of the lumen defined by the cannula.

19. The kit of claim 17 , wherein the catheter has a catheter wall defining a plurality of apertures; and
wherein each aperture of the plurality of apertures is disposed on the coil when the catheter is in the second configuration.

20. The kit of claim 17 , wherein the catheter has a catheter wall defining a plurality of apertures;
wherein the coil has an outwardly facing side and an inwardly facing side when the catheter is in the second configuration; and
wherein a first set of apertures of the plurality of apertures is disposed on the outwardly facing side of the coil and a second set of aperture
