Clinical Study of Safety and Efficacy for the Relieva Stratus With Elution of Triamcinolone Acetonide

The Spacer is inserted surgically into the ethmoid complex through the use of a sinus access system. Triamcinolone acetonide will be administered into the Spacer for this investigational study. The Spacer will be left in the ethmoid sinus for a period of 28 days. At the end of the implant period, the device is removed with standard instrumentation, during a follow-up office visit.
