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 method of deploying a medical device into a sinus cavity, the method comprising the steps of:
advancing a delivery system into a nasal passage such that a portion of the delivery system is disposed within the nasal passage, the delivery system comprising:
a housing having a housing proximal end, a housing distal end, and defining a first housing opening, a second housing opening, and a housing lumen extending between the first housing opening and the second housing opening;
a cannula having a cannula proximal end, a cannula distal end, and defining a first cannula opening, a second cannula opening, and a cannula lumen extending between the first cannula opening and the second cannula opening, 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, and a pusher distal end slidably disposed in the cannula lumen; and
a catheter having at least a portion disposed in the cannula lumen, the catheter having a catheter proximal end, a catheter distal end, a catheter length extending between the catheter proximal end and the catheter distal end, and defining a first catheter opening, a second catheter opening, a first bend, a coil, and a catheter lumen extending between the first catheter opening and the second catheter opening, the catheter adapted to move between a first configuration in which the portion of the catheter disposed within the cannula lumen is substantially straight when disposed in the cannula lumen and a second configuration in which the catheter defines the first bend and the coil along the catheter length when the catheter is free of the cannula lumen;

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;
withdrawing the delivery device from the nasal passage; and
withdrawing the catheter from said sinus cavity and the nasal passage.

2. The method of claim 1 , further comprising the steps of:
introducing medication into the catheter lumen and said sinus cavity;
allowing for an interval of time to pass, the step of allowing for an interval of time to pass being completed subsequent to the step of introducing medication into the catheter lumen; and
repeating the step of introducing medication into the catheter lumen and said sinus cavity subsequent to the step of allowing for an interval of time to pass.

3. The method of claim 2 , wherein the interval of time comprises one or more days.

4. The method of claim 2 , wherein the medication introduced into the catheter lumen and said sinus cavity comprises one of saline, a steroid, an antibiotic, an anti-inflammatory agent, an anti-fungal, a surfactant, and an antihistamine.

5. The method of claim 1 , further comprising the step of trimming the length of the catheter.

6. The method of claim 1 , wherein the catheter has a catheter wall and defines a plurality of apertures, each aperture of the plurality of apertures extending through the catheter wall and in communication with the catheter lumen.

7. The method of claim 6 , wherein in the second configuration the catheter defines the coil between the first bend and the catheter distal end.

8. The method of claim 7 , wherein in the second configuration the catheter defines each aperture of the plurality of apertures on the coil.

9. The method of claim 1 , wherein in the second configuration the catheter defines a second bend disposed between the first bend and the coil;
wherein in the second configuration the catheter defines the first bend at a first angle; and
wherein in the second configuration the catheter defines the second bend at a second angle that is different than the first angle.

10. A method of deploying a medical device into a sinus cavity, the method comprising the steps of:
advancing a catheter over a wire guide having a wire guide proximal end and a wire guide distal end such that a portion of the catheter is disposed on the wire guide, the catheter having a catheter proximal end, a catheter distal end, a catheter length extending between the catheter proximal end and the catheter distal end, and defining a first catheter opening, a second catheter opening, a first bend, a coil, and a catheter lumen extending between the first catheter opening and the second catheter opening, the catheter adapted to move between a first configuration in which the portion of the catheter disposed on the wire guide is substantially straight when disposed on the wire guide and a second configuration in which the catheter defines the first bend and the coil along the catheter length when the catheter is free of the wire guide;
advancing the wire guide into a nasal passage such that the wire guide distal end and the catheter distal end are disposed within the nasal passage;
navigating the wire guide distal end toward a point of treatment;
applying a distal force on the catheter such that it is advanced over the wire guide and into an opening;
continuing the application of a distal force on the catheter such that the catheter distal end passes through the opening and into said sinus cavity and the catheter moves from the first substantially straight configuration to the second configuration and defines the coil within the sinus cavity;
withdrawing the wire guide from the nasal passage; and
withdrawing the catheter from said sinus cavity and the nasal passage.

11. The method of claim 10 , further comprising the steps of:
introducing medication into the catheter lumen and said sinus cavity;
allowing for an interval of time to pass, the step of allowing for an interval of time to pass being completed subsequent to the step of introducing medication into the catheter lumen; and
repeating the step of introducing medication into the catheter lumen and said sinus cavity subsequent to the step of allowing for an interval of time to pass.

12. The method of claim 11 , wherein the interval of time comprises one or more days.

13. The method of claim 10 , further comprising the step of trimming the length of the catheter.

14. The method of claim 10 , wherein the catheter has a catheter wall and defines a plurality of apertures, each aperture of the plurality of apertures extending through the catheter wall and in communication with the catheter lumen.

15. The method of claim 14 , wherein in the second configuration the catheter defines the coil between the first bend and the catheter distal end.

16. The method of claim 15 , wherein in the second configuration the catheter defines each aperture of the plurality of apertures on the coil.

17. The method of claim 10 , wherein in the second configuration the catheter defines a second bend disposed between the first bend and the coil;
wherein in the second configuration the catheter defines the first bend at a first angle; and
wherein in the second configuration the catheter defines the second bend at a second angle that is different than the first angle.

18. A method of deploying a medical device into a sinus cavity, the method comprising the steps of:
advancing a catheter over a wire guide having a wire guide proximal end and a wire guide distal end such that a portion of the catheter is disposed on the wire guide, the catheter having a catheter proximal end, a catheter distal end, a catheter length extending between the catheter proximal end and the catheter distal end, and defining a first
