1. A device for dilating a drainage pathway of a sinus cavity, comprisinga handle;
- an inner guide member secured to the handle and defining a first lumen;
a sleeve member defining a second lumen, wherein the inner guide member is at least partially disposed within the second lumen;
a balloon disposed on the sleeve member;
a rounded tip member disposed at a position that is distal to a distal tip of both the sleeve member and the inner guide member, the rounded tip member secured to a wire that extends proximally through the first lumen of the inner guide member and terminates in a ball;
an end portion forming a proximal end of the sleeve member and disposed inside the handle, the end portion including a chamber and having at least one detent therein that segments the chamber into a proximal chamber portion and distal chamber portion, wherein the ball is located in the chamber; and
a balloon advancement member configured to advance the sleeve member along the inner guide member.

7. A method of treating a sinus cavity of a patient, comprising:
-
providing the balloon dilation catheter comprising; an inner guide member defining a first lumen; a sleeve member defining a second lumen, wherein the inner guide member is at least partially disposed within the second lumen; a balloon disposed on the sleeve member; a rounded tip member disposed at a position that is distal to a distal tip of both the sleeve member and the inner guide member; a balloon advancement member configured to advance the sleeve member along the inner guide member; and
;a means for moving the rounded tip member; directing a distal end of the inner guide member into the head of a patient through a nostril; directing the distal end of the inner guide member to a position near a sinus drainage pathway; advancing the sleeve member off the distal tip of the inner guide member and to a desired position within the sinus drainage pathway, wherein the rounded tip member remains next to the distal end of the sleeve member during the advancement of the sleeve member; and inflating the balloon to dilate the tissue defining the desired position.
