Like its predicate, the Envisu™ Spectral Domain Ophthalmic Imaging System (SDOIS) is a nearinfrared scanning imaging medical device designed to capture depth-resolved images of ocular tissue microstructure. It is available in "high (HR)" and "very-high (VHR)" resolution based on the SLED light source chosen. Each option includes an optical engine, a scanning head, an interchangeable lens set, a computer and the InVivoVue™ Clinic software for imaging of ocular tissue microstructures. The smaller system footprint and mobile security cart easily accommodate any clinical environment. {4}------------------------------------------------ | Envisu™<br>System | Maximum<br>Detector<br>Bandwidth (nm) | Maximum Image<br>Depth (mm in<br>tissue)1 | Pixel Resolution<br>(µm in tissue, 1024<br>pixels full depth) | Detection Type | |-------------------|---------------------------------------|-------------------------------------------|---------------------------------------------------------------|-----------------------------------| | C2200 | 160 | 1.7 | 1.6 | Transmission | | C2300 | 110 | 2.5 | 2.4 | Spectrometer,<br>Line-scan Camera | The optical engine includes a low power broadband LED light source with bandwidths of 40 - 100 nm operating in the wavelength range between 760 - 930 nm and a spectrometer that detects backscattered radiation. The scanning head is flexibly designed to be used mounted or handheld for the mutual convenience and comfort of patient and ciinician. Handheld use of the light-weight (< 3.5 lbs), compact handheld scanner makes it possible to image pediatric patients, supine patients, or any patient that finds it difficult to sit upright or where it is clinically preferable to image without the constraint of a chin rest. Tabletop, chin-rest mediated imaging is enabled though a mounting accessory. #### NON-CLINICAL PERFORMANCE AND SAFETY DATA IEC-60601-1 electrical, IEC 60601-1-2 electromagnetic compatibility, IEC 60825-1 and ISO 15004-2 Group I optical emission and Class 1 LED safety, image resolution, image comparison and software validation testing have been conducted in accordance with established protocols. All testing has demonstrated compliance with applicable product requirements. #### CLINICAL LITERATURE REVIEW A review of existing peer-reviewed clinical literature publications has been completed. Published clinical data reported that the handheld SDOIS is a safe, noninvasive and effective method for evaluation of the eye for pediatric populations. Clinical testing has not been conducted independently by Bioptigen. #### CONCLUSION New Traditional 510/k) The Envisu™ SDOIS has the same fundamental technology, method of operation and technological characteristics as the predicate SDOIS. It introduces new characteristics of mobility and ergonomic utility, including handheld imaging operation, which impact indications for use. Results of performance and safety testing verify that these modifications present no new issues regarding the Envisu™'s safety or effectiveness, and that the Envisu™ SDOIS remains a Class 1 LED , group 1, nonhazardous device eye safe under all operating conditions. In conclusion, the Envisu™ SDOIS is substantially equivalent to the predicate SDOIS device when used as labeled. ¹ Values are approximate, based on an average refractive index of 1.38 {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the logo for the U.S. Department of Health & Human Services.
