Frontal sinus dilation catheter

摘要

A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

1. A method of treating a sinus cavity of a subject using a balloon dilation catheter, the method comprising:
providing a balloon dilation catheter that includes
a handle,an inner guide member extending longitudinally from the handle,a movable shaft coupled to a balloon and slidably mounted on the inner guide member, anda balloon advancement member configured to advance the shaft and the balloon in a distal direction over the inner guide member; advancing the inner guide member to a desired location in a drainage pathway of the sinus cavity of the subject via a nasal passageway; advancing the shaft and balloon in the distal direction over the inner guide member while keeping the inner guide member static relative to the desired location in the drainage pathway, wherein advancing the shaft and balloon places the balloon at the desired location in the drainage pathway; and inflating the balloon.
