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.
Claims15
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 sinusitis.
