The device description focuses on the physical components and functionality related to laser and illumination delivery for surgical procedures. There is no mention of AI, ML, image processing, or any software-driven decision-making or analysis.
Yes.
The device is used to perform endo-ocular laser photocoagulation treatments in vitreoretinal surgery, which is a therapeutic intervention.
No.
The device is intended for "endo-ocular laser photocoagulation treatments," which are therapeutic procedures, not diagnostic ones.
No
The device description clearly outlines physical components such as fiber optics, laser adapters, handles, metal tubing, and protective sheaths. It also details material composition (glass, plastic) and physical dimensions. This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "to perform endo-ocular laser photocoagulation treatments" in vitreoretinal surgery. This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a surgical tool (laser probe) used to deliver laser energy and potentially illumination to the surgical site. It is not designed to analyze samples from the human body (like blood, urine, tissue, etc.) to provide diagnostic information.
- IVD Definition: In Vitro Diagnostics are defined as medical devices and accessories used to examine specimens derived from the human body in vitro (outside the body) to provide information for diagnostic, monitoring, or compatibility purposes.
This device clearly falls under the category of a surgical device used for treatment, not a device used for in vitro diagnostic testing.

Device Description
The Katalyst Revolver Laser Probes are cables made out of one fiber optic (Single-Use), one laser adapter(Reusable), and one handle (Reusable) for surgeon manipulation, metal tubing extending from the handle which penetrates into the surgical site and protective sheath over the fiber.
The fiber for laser transmission is made out of glass, and is restricted for use within the wavelength range of 500nm to 900nm.
The fiber for illumination transmission is made out of either glass or plastic.
The illumination fiber (glass or plastic) is between 100 and 750 microns in size (measure based on the core diameter). The laser fiber (glass) is between 150 and 300 microns in size (measure based on the core diameter).
The tubing is provided in four different variations are referred to as straight, Curved, Flex-Curved, Steerable and Articulating. The configuration is chosen based on the surgeon requirements. The total length of the device is 8-10 feet.
In case of laser and illumination functionalities provided by the same probe, the common protective sheath runs for 1-2 feet, while both branches run for the remainder of the 8-10 feet with each branch having its own protective sheath and each branch ending with its own adapter. The same tubing will then hold within its internal diameter the laser fiber and the illumination fiber.
The Revolver Laser Probes can only be used with a medical laser at an operating wavelength range of 500nm to 900nm. The Revolver Illumination Probes can only be used with the light wavelength range of 425nm to 700nm.

SUMMARY OF EQUIVALENCE
The technological characteristics are identical to the predicate device, in terms of the indication for use, target population, optical output, materials, performance, sterility, biocompatibility, anatomical sites, human factors, compatibility with environment and other devices. The electrical, thermal and radiation safety is identical, because it's not applicable to any of the devices.
The Revolver Probes design is similar to the predicate devices. The Revolver Probes comes four different gauges (20g, 23g, 25g, 27g) and four different tip configuration (i.e., straight, curved, flex-curved, and steerable). The tip configuration is straight or curved for the predicate devices. The difference in tip variations of the Katalyst Revolver Probes and the straight or curved tips of the predicate devices does not affect the safety or effectiveness of the Katalyst Revolver Probes when used as indicated. A surgeon may use any variation of the tip, straight. curved, flex-curved and steerable: in an identical manner; (2) to perform an identical surgical procedure; and (3) to achieve the same surgical result.
The predicate devices come in 20g, 23g, and 25ga in laser probes, and 20ga in Illuminated laser probes. Katalyst Revolver Probes come in 20ga, 23ga, and 27ga, for laser, illumination and laser illumination probes. The addition of the various gauge sizes does not affect the safety and effectiveness of the device. All the micron sizes are within the range of the pervious cleared predicate device.

Image /page/8/Figure/1 description: The image is a graph that shows the transmission loss in dB/m as a function of wavelength in nm. The x-axis represents the wavelength, ranging from 400 to 1100 nm, and is divided into three regions: Ultra Violet, Visible Band, and Infra-red. The y-axis represents the transmission loss, ranging from 0.1 to 30.0 dB/m. There are two curves on the graph, labeled "INDUSTRIAL" and "OPTICAL", which show the transmission loss for different materials.
Furthermore, the predicate devices are single-use devices. The revolver probes are assembled with single-use, and reusable components. Revolver probes comprise three components, handle, fiber and an adapter. The handle and adapter are reusable and are provided nonsterile. The replaceable fiber is a single-use component, and is provided sterile. This change from the predicate device does not have any impact on the safety and effectiveness of the device. The predicate devices and The Revolver Probes are intended as accessories to devices used to coagulate or cut tissue of the eye, orbit, or surrounding skin by a laser beam and to provide illumination during vitroretinal surgery. The Revolver Probes are substantially equivalent to the previously cleared devices.
Conclusion
The Katalyst Revolver Probes were shown to be substantially equivalent to previously cleared devices with respect to intended use, indications for use, technological characteristics, performance characteristics, and biocompatibility.
