First Claim
Patent Images
1. A method for delivering a biodegradable implant into a paranasal sinus cavity comprising:
- a) loading one or more biodegradable implants into a conduit having a distal portion;
b) creating access to the paranasal sinus cavity with the loaded conduit; and
c) delivering the one or more biodegradable implants through an opening in the distal portion of the conduit into the paranasal sinus cavity,wherein the one or more biodegradable implants comprise a therapeutic amount of an active agent for the reduction of inflammation from a sinus procedure.

Abstract
The invention provides biodegradable implants for treating sinusitis. The biodegradable implants have a size, shape, density, viscosity, and/or mucoadhesiveness that prevents them from being substantially cleared by the mucociliary lining of the sinuses during the intended treatment period. The biodegradable implants include a sustained release therapeutic, e.g., an antibiotic, a steroidal anti-inflammatory agent, or both. The biodegradable implants may take various forms, such as rods, pellets, beads, strips, or microparticles, and may be delivered into a sinus in various pharmaceutically acceptable carriers.

40. A method for delivering a biodegradable implant into a paranasal sinus cavity comprising:
-
a) loading one or more biodegradable implants into a conduit having a lumen, a distal portion, a side wall, a tip, and an opening in the distal portion; b) creating access to the paranasal sinus cavity with the loaded conduit; and c) delivering the one or more biodegradable implants through the opening in the distal portion of the conduit into the paranasal sinus cavity, wherein the one or more biodegradable implants comprise a therapeutic amount of an active agent for the treatment of inflammation from a sinus procedure.
