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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02502084
Recruitment Status : Completed
First Posted : July 20, 2015
Last Update Posted : December 22, 2017
Information provided by (Responsible Party):
3NT Medical Ltd.

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 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.
