Medical devices, methods, and kits for delivering medication to a bodily passage

1. A medical device delivery system for treating a sinus cavity, the medical device delivery system comprising:

a wire guide having a wire guide proximal end and a wire guide distal end; and

a catheter having at least a portion 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;

wherein the catheter is 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,

wherein in the second configuration the catheter defines a second bend between the first bend and the coil,

wherein in the second configuration the catheter distal end is directed toward the second bend.

2. A medical device delivery system for treating a sinus cavity, the medical device delivery system comprising:

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;

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;

wherein the pusher distal end is adapted to engage with the catheter proximal end to transfer axial movement to the catheter; and

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.

3. The medical device delivery system of claim 2 , wherein in the second configuration the catheter defines the coil between the first bend and the catheter distal end.

4. The medical device delivery system of claim 2 , 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.

5. The medical device delivery system of claim 4 , wherein in the second configuration the coil has an outwardly facing side and an inwardly facing side; and

wherein in the second configuration the catheter defines the plurality of apertures such that 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.

6. The medical device delivery system of claim 2 , wherein in the second configuration the catheter defines a second bend between the first bend and the coil.

7. The medical device delivery system of claim 6 , wherein in the second configuration the catheter distal end is directed toward the second bend.

8. The medical device delivery system of claim 6 , wherein in the second configuration the catheter defines the first bend at a first angle and the second bend at a second angle that is different than the first angle.

9. The medical device delivery system of claim 2 , wherein in the second configuration the catheter defines the first bend at an angle between about 45 degrees and about 135 degrees.

10. A medical device delivery system for treating a sinus cavity, the medical device delivery system comprising:

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;

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 wall, a catheter length extending between the catheter proximal end and the catheter distal end, a marker, and defining a first catheter opening, a second catheter opening, a first bend, a coil, a plurality of apertures, and a catheter lumen extending between the first catheter opening and the second catheter opening, the marker disposed at the first bend, each aperture of the plurality of apertures extending through the catheter wall and in communication with the catheter lumen;

wherein the pusher distal end is adapted to engage with the catheter proximal end to transfer axial movement to the catheter; and

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, the coil defined between the first bend and the catheter distal end.
