Summary

The purpose of this study is to assess the safety and effectiveness of the Peregrine endoscope in patients in the office setting in terms of access into and visualization of the paranasal sinus anatomy, image quality, patient tolerability and clinical utility. Up to 30 participants who have had prior endoscopic sinus surgery (ESS) and 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 the Peregrine Endoscope as well as a standard endoscope. This study aims to: * compare visualization success rates of the paranasal sinus anatomy by Peregrine and by a standard endoscope used in the office setting. * examine device related adverse events. * assess the adequacy of the image quality of Peregrine for endoscopy procedures in the office. * evaluate patient tolerability and pain

Detailed description

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.

Interventions

Type	Name	Description
DEVICE	Peregrine Drivable ENT Scope	Peregrine, developed by 3NT Medical, is a single-use disposable handheld endoscope, which is thinner and more flexible than other endoscopes. The endoscope includes a camera at its end and a working channel. The thin endoscope provides a means to visualize the nasal cavity and paranasal sinus space and to deliver irrigation to treat the sinus ostia (drainage openings) and spaces within the paranasal sinus cavities
DEVICE	Standard 30° 4mm Endoscope	The Standard 30° 4mm endoscopic sinus evaluation is the standard procedure that would normally be used to evaluate the condition of each participant.
