Intended Use

The MicroGRASP Monopolar Coagulator is indicated for use in the grasping and coagulation of soft tissue and blood vessels up to 3 mm during open and guidance-assisted surgical procedures.

Device Description

The MicroGRASP Monopolar Coagulator is an instrument designed for grasping and coagulation of soft tissue and blood vessels during surgical procedures. The MicroGRASP Monopolar Coagulator contains materials similar to those used in the predicate device, is of similar design and has the same operating principle as the predicate device.

AI/ML Overview

The provided document describes a premarket notification for the "MicroGRASP Monopolar Coagulator," a device designed for grasping and coagulation of soft tissue and blood vessels during surgical procedures. The document aims to demonstrate substantial equivalence to a predicate device, the "Microsurge Front-End Grasping Devices."

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in a quantitative sense with corresponding performance metrics for the new device. Instead, it focuses on demonstrating substantial equivalence to a predicate device. The primary "acceptance criteria" appear to be meeting applicable standards and not raising new safety/effectiveness issues compared to the predicate.

Acceptance Criteria (Implied)Reported Device Performance
Compliance with applicable standards (e.g., for electrical safety, performance)"The MicroGRASP Monopolar Coagulator has been designed and tested to applicable standards (ANSI/AAMI HF-18/1993)."
No new issues of safety, effectiveness, or performance compared to predicate."The MicroGRASP Monopolar Coagulator does not raise any new issues of safety, effectiveness, or performance of the product."
Similar intended use to predicate.Intended Use for MicroGRASP is "For grasping and coagulation of soft tissue and blood vessels up to 3 mm during open and guidance-assisted surgical procedures," which is analogous to the predicate's "To remove tissue or control bleeding during general surgical endoscopic or laparoscopic procedures."
Similar operating principle to predicate (Monopolar Electrosurgical handpiece).MicroGRASP: "Electrosurgical handpiece for coagulation." Predicate: "Electrosurgical handpiece for coagulation; electro-cautery." Both are Monopolar.
Similar materials and design to predicate."The MicroGRASP Monopolar Coagulator contains materials similar to those used in the predicate device, is of similar design and has the same operating principle as the predicate device." Specific material comparisons are provided in the table.

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

The document does not mention a "test set" in the context of clinical or performance data from a sample of cases or patients. The evaluation appears to be based on bench testing and comparison of technical characteristics. Therefore, information on sample size for a test set, country of origin, or retrospective/prospective nature is not provided.

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

This information is not provided as the submission relies on bench testing and comparison to standards, not human expert evaluation of a test set in the traditional medical device study sense.

4. Adjudication Method for the Test Set

This information is not provided as there is no described test set that would require adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable. The device is a mon-AI surgical instrument (Monopolar Coagulator), not an AI diagnostic or assistance tool. Therefore, an MRMC study related to AI assistance for human readers was not performed or mentioned.

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

This is not applicable. The device is a physical surgical instrument, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the device's acceptable performance appears to be:

  • Compliance with published standards: Specifically, ANSI/AAMI HF-18/1993 for electrosurgical devices.
  • Demonstration of substantial equivalence to a legally marketed predicate device (Microsurge Front-End Grasping Devices) in terms of intended use, operating principle, and technical characteristics.

8. The Sample Size for the Training Set

This is not applicable. The device is a physical surgical instrument, and there is no mention of a "training set" in the context of machine learning or AI development.

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

This is not applicable for the same reason as above.

Dear Dr. Gordon:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
