Abstract:
1. A system for treating a disease or disorder of the ear, nose or throat of a human or animal subject, said system comprising: a guide catheter that is insertable into the head of the subject, said guide catheter having a substantially rigid shaft, a proximal opening, a distal opening and a lumen extending between the proximal opening and the distal opening; a handle having bore, a portion of the handle being insertable into the proximal opening of the guide catheter such that the bore of the handle is in alignment with the lumen of the guide catheter; a working catheter having a substantially rigid proximal shaft portion and a distal shaft portion that is sufficiently flexible to assume various shapes and a guidewire lumen; a guidewire that is advanceable through the guidewire lumen; a member attached to the guidewire to a) facilitate grasping of the guidewire, b) limit the extent to which the guidewire is advanceable through the guidewire lumen and c) hold the guidewire in a substantially fixed position relative to the working catheter when the guidewire has been fully advanced; and the working catheter being insertable through the bore of the handle and through the lumen of the guide catheter to a position where some of the distal shaft portion but none of the substantially rigid proximal portion extends out of the distal end of the guide catheter and some of the substantially rigid proximal shaft portion but none of the distal shaft portion extends out of the proximal end of the guide catheter.
