Abstract
Described here are devices, methods, and kits for treating sinusitis and related respiratory conditions by locally delivering active agents to the osteomeatal complex over a sustained period of time. The devices may be passively fixed within the osteomeatal complex and/or include one or more features that actively fix it within the osteomeatal complex. The devices may optionally include a portion that extends into a sinus ostium, sinus cavity, and/or the nasal passage to deliver an active agent.
