Primary Outcome Measures:
  • Safety assessed by unanticipated device-related adverse events [ Time Frame: During hospital stay, up to 1 day ]

Secondary Outcome Measures:
  • Performance assessed by anatomical landmarks reached and visualized will be recorded [ Time Frame: During procedure, up to 3 hours ]

Enrollment: 17
Study Start Date: August 2015
Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: April 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 3NT flexible endoscope
Evaluation of 3NT flexible endoscope in terms of access and evaluation of the nasal anatomy
Device: 3NT flexible endoscope
The nasal anatomy will be accessed and viewed with the device during functional endoscopic sinus surgery (FESS) procedure.
Other Name: Sinusway

Detailed Description:
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.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female patient indicated for primary FESS procedure by the ear, nose and throat (ENT) specialist
  • 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
  • Patients with previous FESS surgery
