Device uses diode-pumped solid-state (DPSS) laser to produce 561 nm (yellow) light pulses. Yellow wavelength provides high absorption by melanin in retinal pigment epithelium/choroids and hemoglobin; facilitates treatment for retinal/choroidal neovascularization; allows transmission through cloudy media (cataracts/corneal haze). Used by ophthalmologists in clinics or retinal specialist offices. Laser pulses delivered via integrated slit-lamp microscope or optional Laser Indirect Ophthalmoscope (LIO). Physician positions laser using aiming beam; triggers pulses via footswitch. Output affects ocular tissue via photocoagulation to treat specified pathologies. Benefits include improved penetration of hemorrhaging tissue and fluids compared to green/red lasers. ## Clinical Evidence No clinical data provided. Substantial equivalence is based on bench testing and comparison of technological characteristics to legally marketed predicate devices. ## Technological Characteristics True CW Diode-Pumped Solid-State (DPSS) laser; 561 nm wavelength; 50-1500 mW power; 0.01-4.0s pulse duration. Integrated slit-lamp microscope delivery system. Air-cooled with active thermo-electric cooler. Class 4/IV laser. Aiming laser: semiconductor diode, <1 mW, 635 nm. Electrical: 90-240VAC, 50/60Hz. Dimensions: console 140x280x350 mm, 14.5 kg. ## Regulatory Identification An ophthalmic laser is an AC-powered device intended to coagulate or cut tissue of the eye, orbit, or surrounding skin by a laser beam. ## Predicate Devices - Ellex Integre Duo LP1RG ([K052777](/device/K052777.md)) ## Reference Devices - Lumenis Novus Varia ([K022181](/device/K022181.md)) - Nidek MC-7000 ([K974732](/device/K974732.md)) - Nidek MC-300 ([K042785](/device/K042785.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The Integre family are designed for use by ophthalmologists in a clinic or outpatient facility, or in the Retinal Specialist's office. The Integre Duo LP1RG device is capable of producing focused pulses of red or green light with wavelengths of 670 nanometres (nm) and 532 nm respectively. The red and green beams may be used for the same treatments, but the red gives increased penetration of haemorrhaging tissue and fluids, and may also be used to treat ocular melanomas. The Integre LP561 is essentially the same device with a modification to the laser cavity optical components which results in a vellow (561 nm) treatment laser output. The reason for developing the new device is because the yellow wavelength is characterised by high absorption by melanin in the retinal pigment epithelium and choroids that reduces the {1}------------------------------------------------ Image /page/1/Picture/0 description: The image shows a logo for "ellex" inside of a circle.

As with the Integre LP1RG, the laser pulses are accurately positioned on a structure within the patient's eye with the aid of a delivery device. The delivery device is an integrated slit-lamp microscope. An optional Laser Indirect Ophthalmoscope (LIO) can also be used. The Integre Duo is a ophthalmic photocoagulator laser designed to be used by ophthalmologists for treatment of ocular pathology of the eye. It is expected that the user is trained in operation of the instrument. This is the same intended use as previously cleared for Integre Duo laser 510(k) K052777 The Indications for Use statement can be found in Attachment 2 Refer to the following tables for a comparison of the Integre LP561 with the Integre Duo LP1RG and other commercially available predicate devices ### Intended Use: Comparison of Technological Characteristics: {2}------------------------------------------------ | Characteristic compared | Integre LP561 | Integre Duo LP1RG;

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. {7}------------------------------------------------ This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at 240-276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at 240-276-3464. You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
