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

摘要

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.

主权项

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; anda 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.
