BALLOON DILATION CATHETER FOR USE IN SINUS DRAINAGE PATHWAYS

摘要

The present disclosure provides a balloon dilation catheter that includes a handle (102), a substantially rigid inner guide member (108) coupled to the handle, a shaft (118) arranged over the inner guide member, a balloon (120) coupled to the inner guide member, and a polymer ball tip (122) positioned at a distal end of the balloon. To treat a sinus drainage pathway of a subject using the balloon dilation catheter, the substantially rigid inner guide member is positioned into the drainage pathway of the sinus of the subject via a nasal passageway. The balloon is then inflated to expand or otherwise remodel the drainage pathway.
