Safety and Effectiveness of the Peregrine Drivable ENT Scope for Endoscopy of the Paranasal Sinuses

Nasal endoscopy is a minimally invasive, diagnostic medical procedure and currently the most preferred initial method of evaluating medical problems affecting nose and sinuses such as nasal stuffiness and obstruction, sinusitis, nasal polyposis, nasal tumors, epistaxis, recurrent bouts of sneezing and rhinorrhea. Overall, the procedure is considered very safe and low-risk. Currently, nasal endoscopy can be performed with a flexible or rigid endoscope, typically after a topical decongestant and anesthetic are applied to the nasal mucosa. Reprocessing is an issue of concern, especially for flexible endoscopes where multiple steps were confirmed to be critical for reprocessing to be effective. High-level disinfection has been determined to be the minimum level of disinfection required, which involves multiple steps including manual cleaning, leak testing, cleaning with an enzymatic agent, high-level disinfection, and drying with vertical storage. 3NT Medical Ltd. has developed the Peregrine Drivable Ear Nose and Throat (ENT) Scope, which offers the convenience of a single-use endoscope component coupled with performance characteristics of commercially available state-of-the-art reusable endoscopy systems. The single-use endoscope essentially removes concerns related to burdensome reprocessing techniques of a delicate tool required to achieve high-level of its disinfection. The objective of this study is to assess the safety and performance of the Peregrine endoscope in patients in the office setting in terms of access and visualization of the paranasal sinus anatomy, image quality, and patient tolerability and pain. For this study, up to 30 patients who have had prior endoscopic sinus surgery (ESS) and who are scheduled for nasal endoscopy in the office, as part of a routine post-operative office visit or due to recurrence of symptoms, will be evaluated with Peregrine Endoscope. Access and visualization by an additional standard endoscope will be conducted and compared to Peregrine endoscope. Image quality of the Peregrine endoscope, participant tolerability and pain, and the impact of Peregrine on clinical decision making will be evaluated.
