Abstract
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.
Claims22
A method of treating a sinus cavity of a subject comprising:
- providing a balloon dilation catheter that includes
- a handle defining a slot extending along a longitudinal exterior surface of the handle,
- a balloon mounted on a shaft,
- a first lumen extending through the shaft,
- a second lumen in fluidic communication with the balloon,
- an inner guide member extending through the first lumen,
- an inflation port in fluidic communication with a proximal end of the second lumen, and
- a balloon advancement member slidably disposed within the slot wherein the second lumen does not extend through the balloon advancement member;
- advancing the inner guide member through a nostril of the subject while at least a portion of the inner guide member is disposed within the first lumen;
- advancing the inner guide member to a desired location within a drainage pathway of the sinus cavity;
- advancing the balloon advancement member distally to a position along the handle that is distal with respect to the inflation port to place the balloon at the desired location;
- and
- directing a fluid through the inflation port to inflate the balloon at the desired location.
