Katalyst Cyclophotocoagulation Probe is intended, when used with an infrared laser, for Transscleral Cyclophotocoagulation (TSCPC) of the ciliary process.

Device Description

The Cycloprobe is a single use device sold sterile. The Cycloprobe is made out of one fiberoptic, one laser machine connector, one handle for surgeon manipulation, one clear tip for placement on the eye, and a protective sheath over the fiber. On the distal side, the fiberoptic is terminated by a connector that attaches to the laser machine. On the other side, it is terminated by a fiber that has a ball lens formed onto the end that protrudes slightly from the clear tip. The connector configuration is chosen based on the surgeons' laser machine requirements. The total length of the device is 7 feet.

AI/ML Overview

This document is a 510(k) summary for the Katalyst Cyclophotocoagulation Probe, indicating that it is a medical device application to the FDA, asserting substantial equivalence to a predicate device. It primarily focuses on the regulatory approval process and does not contain information about clinical studies with human readers or AI algorithms for diagnostic purposes. As such, many of the requested fields are not applicable to the content provided.

Here's an analysis based on the provided text:

1. Table of acceptance criteria and the reported device performance

Since this is a 510(k) application asserting substantial equivalence, the "acceptance criteria" are the characteristics of the predicate device, and the "reported device performance" are the characteristics of the applicant device. The document states that the performance is "identical" to the predicate.

Characteristic / Acceptance Criteria (Predicate: Iridex G-Probe)	Reported Device Performance (Katalyst Cycloprobe)
Indications for Use	Identical
Target Population	Identical
Design	Similar
Optical Output	Identical
Materials	Identical
Performance	Identical
Sterility	Identical
Biocompatibility	Identical
Anatomical Sites	Identical
Human Factors	Identical
Energy Used and/or Delivered	Identical

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not applicable. The document states "Clinical Testing was not required to prove substantial equivalence." The evaluation was based on bench testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. No clinical testing with expert assessment of ground truth was conducted.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. No clinical testing with ground truth adjudication was conducted.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is a surgical probe, not an AI diagnostic tool. No MRMC study was conducted.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This device is a surgical probe, not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable. No clinical ground truth was established as clinical testing was not conducted. The "ground truth" for substantial equivalence was the characteristics and performance of the predicate device.

8. The sample size for the training set

Not applicable. This device does not involve AI algorithms that require a training set.

9. How the ground truth for the training set was established

Not applicable. No AI training set was used.

Dear Meryl Koch:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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); medical device reporting (reporting of

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

medical device-related adverse events) (21 CFR 803); 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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Industry and Consumer Education at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address
