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 cannula lumen extending between a first cannula opening and a second cannula opening;
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;
a coating disposed on the catheter; and
a pusher having a pusher proximal end and a pusher distal end slidably disposed in the cannula lumen and adapted to engage with the catheter proximal end to transfer axial movement to the catheter;
wherein the catheter is 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.

2. The medical device of claim 1 , wherein the coating is disposed along the entire catheter length.

3. The medical device of claim 1 , wherein the coating is disposed along a portion of the catheter length.

4. The medical device of claim 1 , wherein the coating is adapted to prevent biofilm formation on the catheter.

5. The medical device of claim 1 , wherein the coating is adapted to prevent or reduce microbial colonization on the catheter.

6. The medical device of claim 5 , wherein the coating is selected from the group consisting of antibiotics, antifungals, and antiseptics.

7. The medical device of claim 5 , wherein the coating comprises one of rifampin, minocycline, and chitosan.

8. The medical device of claim 1 , wherein the coating is a lubricious coating.

9. The medical device of claim 8 , wherein the coating is selected from the group consisting of hydrophilic coatings and polymer coatings.

10. The medical device of claim 8 , wherein the coating comprises polytetrafluoroethylene.

11. The medical device of claim 1 , wherein the catheter has a catheter wall; and
wherein the catheter defines a plurality of apertures along the catheter length, each aperture of the plurality of apertures extending through the catheter wall and in communication with the catheter lumen.

12. The medical device of claim 11 , wherein the plurality of apertures is disposed distal to the bend.

13. The medical device of claim 11 , wherein at least two of the plurality of apertures have different diameters.

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

15. The medical device of claim 1 , wherein the catheter proximal end is flared.

16. The medical device of claim 1 , wherein the catheter distal end is tapered.
