Sinusitis treatment system and method of use
A system for manipulating a guide catheter within a patient's nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.
