## Indications For Use:

Laser Probes and Illuminated Laser Probes:

For use in vitreoretinal surgery to perform endo-ocular laser photocoagulation treatments at operating wavelength of 500nm to 900nm.

#### Device Description:

The laser probes are cables made out of one fiberoptic, one laser connector, one handle for surgeon manipulation, stainless steel tubing extending from the handle which penetrates into the surgical site, and protective sheath over the fiber.

The illuminated laser probes (referred to also as "laser/illumination probes") are cables made out of two fiberoptics (one for laser and one for illumination), one laser connector, one illumination connector, one handle for surgeon manipulation, stainless steel tubing extending from the handle, and protective sheath over both fiberoptics.

{1}------------------------------------------------

On one side, the distal side, the fiberoptic is terminated by a connector that attaches to the machine, be it laser or illumination. On the other side, it is terminated by a stainless steel tubing which penetrates into the eye, and may be 20g, 23g, or 25g in size in case of laser probes, or 20g in case of laser/illumination probes.

KIZIJBT

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 is made out of either glass or plastic. The tubing is provided in two shapes, referred to as straight or curved. The configuration is chosen based on the surgeon requirements. The total length of the device is 10 feet.

In case of laser and illumination functionalities provided by the same probe, the common protective sheath runs for 1 foot, while both branches run for 9 feet with each branch having its own protective sheath and each branch ending with its own connector. The same tubing will then hold within its internal diameter the laser fiber and the illumination fiber.

#### Predicate Devices:

The Katalyst Illuminated Laser Probe was shown to be substantially equivalent to the previously cleared devices (K050807 and K021696).

### Substantial Equivalence:

## SUMMARY OF EVALUATION

12/18

Bench testing performed on this device and compared to the predicate indicates that the Katalyst Illuminated Laser Probes and Laser Probes are substantially equivalent to predicate devices. Bench testing of the Katalyst Illuminated Laser Probes and Laser Probes was performed in accordance with FDA Guidance on the Content and Organization for a Medical Laser. Biocompatibility testing was performed in accordance with ISO 10993. Sterilization development, validation, and control were performed in accordance with ISO 11135-1. Product shelf-life was established in accordance with ASTM Standard #F 1980-09 (2011) and packaging integrity was established in accordance with ASTM F 1929-04 and ASTM F88/F88M-09. Optical radiation safety testing was performed in accordance with ISO 15752 and ISO 15004-2.

### SUMMARY OF EQUIVALENCE

Design: The tip configuration is straight for the predicate devices and the tip configuration may be straight or curved for the Katalyst Laser and Illuminated Laser Probes ("Probes"). The difference in design between the curved tips of the Probes and the straight tips of the predicate devices does not affect the safety or effectiveness of the Probes when used as indicated.

The only difference between the straight tip predicate device and the curved tip Probe is that the curved tip Probe may aim the distal end of an optical fiber in a curved direction

{3}------------------------------------------------

K121187

within the inner eye and the straight tip predicate device may aim the distal end of an optical fiber in a straight direction within the inner eye. Compared to the straight tip predicate device, the curved tip Probe: (1) does not allow a surgeon to aim the distal end of an optical fiber at different tissues or types of targets within the inner eye; (2) does not allow a surgeon to perform a different surgical procedure; and (3) does not change the manner that a surgeon may perform a surgical procedure. There is no difference in safety or effectiveness of the straight tip predicate device and the curved tip Probe.

The curved tips of the Probes do not present any inherent safety risk that is not also inherent in a straight tip of the predicate devices. The interface between the device connectors and the illumination or laser machine connectors is identical for Probes with curved tips and predicate devices with straight tips. The optical properties of optical fibers in straight tips of the predicate devices are identical to the optical properties of optical fibers in curved tips of the Probes.

The 510(k) presented the design of the curved tube used for Probes with curved tips and the design of the straight tube used for Probes with straight tips. The straight tubes and the curved tubes are: manufactured from the same material, manufactured with the same inner and outer dimensions, and manufactured at the same overall length. The only between the curved tube and the straight tubes is that the distal end of the curved tubes extends 1.3 inches from the tube proximal end and the distal end of the straight tubes extends 1.4 inches from the tube proximal end. This difference in length is a result of the curved tube being curved, i.e., if a curved tube would be mechanically straightened then the distal end of that straightened tube would extend 1.4 inches from the tube proximal end. This difference does not affect the safety or effectiveness of the Probes.

Energy Used and/or Delivered: The operating range is similar but not identical to the predicate devices. The operating range of the Katalyst Laser and Illuminated Laser Probes ("Probes") is wavelengths of 500 nm to 900 nm. The operating range of the predicate devices is wavelengths of 500 nm to 1100 nm. The difference between the upper limit of operating wavelength of the Probes and the upper limit of operating wavelength of the predicate devices does not affect the safety or effectiveness of the Probes because the upper limit of the wavelength operating range of the Probes falls within the wavelength operating range of the predicate devices.

#### Conclusion

The Katalyst Illuminated Laser Probes and Laser 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.
