Brief Summary:
3NT flexible endoscope is a single-use disposable handheld endoscope that provides a means to visualize the nasal cavity and paranasal sinus space and deliver irrigation to treat the sinus ostia and spaces within the paranasal sinus cavities for diagnostic and therapeutic procedures

Condition or disease Intervention/treatment Phase
Sinusitis Device: 3NT flexible endoscope Not Applicable

Detailed Description:
The rationale behind this feasibility study is to show that access and visualization of the nasal anatomy and paranasal sinuses (Maxillary, Frontal and Sphenoid sinuses) in conjunction with Balloon Sinus Dilation in patients suffering from symptoms attributable to sinusitis is feasible in the office and operating room settings; This is an essential step in the development of a combined dilation and visualization system that will allow visualization, dilation and lavage of the sinuses via their natural ostia during an office visit, and minimize radiation exposure, antibiotic use, multiple office visits, and cost.
