Device and methods for treating paranasal sinus conditions

摘要

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.

1. A method of delivering a paranasal sinus device comprising:
advancing a bioabsorbable expandable device into a paranasal sinus cavity with a delivery device, the expandable device being sized and shaped to fit within a paranasal sinus cavity and being at least partly conformable to the shape thereof, the expandable device comprising a pronged structure comprising a plurality of filaments that expand radially outwardly, each filament having a proximal end and a distal end, wherein only the proximal ends of each filament join together, and wherein the distal end of each filament is a free distal end; and withdrawing the delivery device, wherein the expandable device remains in and at least partially conformed to the paranasal sinus cavity after the delivery device has been completely withdrawn.
