Abstract

Described here are paranasal sinus devices for treating paranasal sinus conditions. The devices include a cavity member, ostial member, and nasal portion. One or more of the cavity member, ostial member, and nasal portion may deliver an active agent for sustained release to treat the paranasal sinus condition. Exemplary paranasal sinus conditions are sinus inflammation due to functional endoscopic sinus surgery (FESS) and rhinosinusitis.
