Abstract
Devices, methods and kits which, when installed or used, access, aspire, dilate, insufflate, drain or deliver fluid medicaments to, or place a patency device within a sinus area, such as a maxillary sinus or a maxillary sinus ostium. The device can include a hollow catheter and probe, and can be configured to permit gradual and incremental probe extension. The device can be constructed to enhance the precision and maneuverability within the nasal and sinus passageways, while also accommodating the natural anatomical geometry of a targeted paranasal treatment site. For example, the present treatment and placement device can accomplish access to the maxillary sinus ostium by utilizing an uncinate process to guide a probe tip into the ostium in a retrograde manner. The probe can be slidably, bi-directionally or co-axially positioned within the catheter. A distal portion of the probe can be biased away from a longitudinal axis of the catheter.
