1. A fully-implantable paranasal sinus device comprising:
- a tube-like ostial member shaped and sized to fit within a paranasal sinus ostium, wherein the ostial member comprises a lumen extending therethrough and a plurality of apertures along the length of the ostial member;
a nasal portion configured to extend into a nasal cavity, the nasal portion comprising a nasal plate connected to the ostial member and sized to fit within the nasal cavity, the nasal plate comprising an aperture in communication with a lumen of the ostial member; and
a cavity member shaped and sized to fit within a paranasal sinus cavity.

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.
