Safety and Effectiveness Evaluation of the Sinusway Device for Endoscopy of the Nasal Cavity and Paranasal Sinuses

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.

The rationale behind this feasibility study is to show that accessing and visualization of the nasal anatomy and paranasal sinuses (Maxillary, Frontal and Sphenoid sinuses) in patients suffering from symptoms attributable to sinusitis is feasible; This is an essential step in the development of a system that will later allow visualization, sampling, and treatment of the sinuses via the natural sinus ostium during the patient's first office visit in a minimally invasive manner while enabling treatment by lavage, and minimizing radiation exposure, antibiotic use, multiple office visits, and cost.

Inclusion Criteria:

• Patient age: adult (>18 years old)
• Patients in general good health in the opinion of the investigator as determined by medical history physical examination
• A patient who is able to understand the requirements of the study, is willing to comply with its instructions and schedules, and agrees to sign the informed consent

Exclusion Criteria:

• A patient with nasal polyposis
• A patient indicated for tumor excision
• Known history of any significant medical disorder, which in the investigator's judgment contraindicates the patient's participation
• Patients with known current or previous bleeding disorder receiving anticoagulants (e.g., chronic Coumadin treatment)
• Pregnancy
