Study to Evaluate the Safety and Initial Effectiveness of the Sinusway™ for Endoscopy of Sinuses in Conjunction With BSD

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.

Inclusion Criteria:

1. Male or female patient indicated for balloon sinus dilation procedure by the ENT
specialist

2. Patient age: adult (>18 years old)

3. Patients in general good health in the opinion of the investigator as determined by
medical history and physical examination

4. 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:

1. Known history of any significant medical disorder, which in the investigator's
judgment contraindicates the patient's participation

2. Patients with known current or previous bleeding disorder receiving anticoagulants
(e.g., chronic Coumadin treatment)
