Intended Use

This instrument is intended to be used with an Olympus light source, documentation equipment, display monitor and other ancillary equipment for endoscopic diagnosis. This instrument is indicated for use within the nasal and nasopharyngeal lumen.

Device Story

Flexible fiberscope for visualization of nasal and nasopharyngeal anatomy; used in clinical settings by physicians. Device consists of eyepiece, control section for angulation, connector for light source, and insertion tube. Light from external source travels through fiber bundles to distal end; reflected image captured by objective lens and transmitted via image fiber bundles to eyepiece. Physician manually manipulates angulation lever to guide insertion and observation. Provides direct visualization to assist in diagnostic procedures. Benefits include reduced distal end and insertion tube diameters compared to predicate, facilitating navigation within nasal passages.

Clinical Evidence

No clinical or animal studies were performed. Substantial equivalence is supported by bench testing, including electrical safety, thermal safety, mechanical durability, and optical performance testing, alongside biocompatibility and reprocessing validation.

Technological Characteristics

Flexible fiberscope; optical fiber bundles for illumination and imaging. Distal end diameter 3.1mm; insertion tube 3.5mm. Field of view 85°; depth of field 5-50mm. No instrument channel. Compatible with OER-Pro, STERRAD, and V-PRO reprocessing. Electrical safety per ANSI/AAMI ES 60601-1 and IEC 60601-2-18.

Indications for Use

Indicated for endoscopic diagnosis within the nasal and nasopharyngeal lumen.

Regulatory Classification

# 4 Device Description

This instrument is intended to be used with an Olympus light source, documentation equipment, display monitor and other ancillary equipment for endoscopic diagnosis. This instrument is indicated for use within the nasal and nasopharyngeal lumen.

ENF-GP2 is mainly consisted of four functional parts:

- eyepiece section that observes endoscopic images
- control section that operates endoscope such as controlling angulation to guide insertion and observation
- connector section that links with light source -
- insertion section that goes through and contacts with nasal and nasopharyngeal lumen under light guide.

When observing nasal or nasopharyngeal lumen, the light emitted from light source comes into fiberscope via apparatus on connector section and is eventually transmitted and released from examination light outlet in the distal end to supply light by optical fiber bundles. Subsequently the enlighten image reflexed into objective lens is grasped and sent to evepiece section by image fiber bundles, and observer can observe the image in eyepiece section or alter the imaging position by means of operations on control section, such as manipulation by UP/DOWN angulation control lever to adjust the bending section. Each section works collectively to perform observation within nasal and nasopharyngeal lumen.

# 5 Indications for Use
