Intended Use

The TrabEx Pro Handpiece is a manual ophthalmic surgical instrument with irrigation and aspiration functions.

Device Description

The MicroSurgical Technology TrabEx Pro is a single use, sterile, manual ophthalmic knife. The device can be connected to an ophthalmic Irrigation/Aspiration (I/A) system to provide irrigation and aspiration while the procedure is being performed. TrabEx PRO has an incision sealing sleeve.

AI/ML Overview

The MicroSurgical Technology TrabEx Pro is a manual ophthalmic knife with irrigation and aspiration functions. The device was compared to the Trabectome (K040584) to demonstrate substantial equivalence, specifically for its irrigation and aspiration performance.

Here's an analysis of the acceptance criteria and study:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Predicate: Trabectome K040584)Reported Device Performance (TrabEx Pro)
Irrigation Rate: Minimum 3 ml/min at 40 cm bottle height (0.59 psi)Irrigation Rate: Minimum 3 ml/min at 40 cm bottle height (0.59 psi)
Aspiration Rate: 4 ml/min at no more than 250 mmHg (4.8 psi)Aspiration Rate: 4 ml/min at no more than 250 mmHg (4.8 psi)

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample size used for the performance testing of the TrabEx Pro (bench testing). It mentions that "The TrabEx Pro and the Trabectome were tested using the same test methods," implying a comparative bench test.

The data provenance is from bench testing conducted by MicroSurgical Technology, Inc. It does not involve human subjects or clinical data, thus there is no information on country of origin or retrospective/prospective nature.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. The ground truth for this device's performance (irrigation and aspiration rates) was established through objective physical measurements in a lab setting, not through expert opinions or clinical evaluation. The performance was directly measured against the specified rates of the predicate device.

4. Adjudication Method for the Test Set

Not applicable. Since the "ground truth" was based on objective physical measurements of flow rates, there was no need for adjudication involving human experts.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No. This device is a surgical instrument whose performance was evaluated based on physical operating parameters (irrigation and aspiration rates) in a bench test, not on an imaging-based diagnosis or interpretation that would typically involve a multi-reader study.

6. If a Standalone Study (Algorithm Only Without Human-in-the-Loop Performance) was Done

Yes, in essence. The performance evaluation of the TrabEx Pro for irrigation and aspiration was a standalone assessment of the device's physical capabilities in a controlled bench test environment, without human surgical interaction being part of the primary performance measurement for regulatory submission.

7. The Type of Ground Truth Used

The ground truth used for establishing substantial equivalence was based on objective, quantitative physical measurements of irrigation and aspiration rates, mimicking the performance parameters of the legally marketed predicate device (Trabectome).

8. The Sample Size for the Training Set

Not applicable. This device is a manual surgical instrument, not an AI or machine learning algorithm. Therefore, there is no "training set" in the context of an algorithm.

9. How the Ground Truth for the Training Set was Established

Not applicable for the same reason as point 8.

Dear Ms. Angela Mallery:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

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

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

§ 880.5725 Infusion pump.

(a)
Identification. An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.(b)
Classification. Class II (performance standards).
