AI/ML Overview

The provided text describes a 510(k) premarket notification for the Voyant® Electrosurgical Generator and Voyant® 5mm Sealer-Divider System. It outlines the device's indications for use, technological characteristics, and performance testing conducted to demonstrate substantial equivalence to predicate devices. However, the document does not contain a table of acceptance criteria and reported device performance in a way that directly answers the request. It states that testing was performed but does not list specific numerical criteria or outcomes in a clear tabular format for direct comparison.

Therefore, for the information requested in your prompt, I can only extract what is available and highlight what is missing.

Here's an attempt to answer based on the provided text, noting the limitations:

1. A table of acceptance criteria and the reported device performance

The document states its Indications for Use which implicitly sets a performance expectation: "The device can seal and divide vessels up to and including 7mm in diameter and tissue bundles that can be captured in the jaws of the device."

However, specific numerical acceptance criteria (e.g., minimum burst pressure, maximum thermal spread) and the precise reported performance values against these criteria are not explicitly presented in a table. The document generally concludes that the system is "substantially equivalent in performance to the predicate system with respect to vessel sealing performance and local tissue effects."

Acceptance Criteria (Implied from Indications for Use and Testing Goals)	Reported Device Performance (General Statement in Document)
Ability to seal and divide vessels up to 7mm in diameter.	"substantially equivalent in performance to the predicate system with respect to vessel sealing performance"
Ability to seal and divide tissue bundles that can be captured in jaws.	"substantially equivalent in performance to the predicate system with respect to vessel sealing performance"
Acceptable local tissue effects (thermal damage).	"substantially equivalent in performance to the predicate system with respect to... local tissue effects."
Electrical, mechanical, and functional capabilities.	Tested in accordance with IEC 60601-1-2 and IEC 60601-2-2. Basic mechanical and functional capabilities were tested.
System safety and efficacy.	Evaluated in preclinical bench and animal studies; chronic hemostasis evaluated.

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

Test Set Sample Size: The document mentions "preclinical bench (ex vivo porcine vessels/tissue)" and "acute animal study (in vivo canine model)," and "a chronic study (in vivo canine model)." No specific sample sizes (e.g., number of porcine vessels, number of canine subjects) are provided.
Data Provenance:
- Country of Origin: Not specified.
- Retrospective or Prospective: The preclinical and animal studies are prospective in nature, as they involve testing the device under controlled conditions.

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)

This section is not applicable as the studies are device performance studies on animal/ex vivo models, not studies requiring expert interpretation of diagnostic images or clinical outcomes in humans to establish ground truth. The "ground truth" for these types of studies would be objective measurements (e.g., burst pressure measurements, histological assessment of thermal damage) performed by trained technicians or researchers. The document does not specify the number or qualifications of individuals performing these measurements.

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

This section is not applicable for the type of device performance studies described. Adjudication methods are typically used in clinical or diagnostic studies to resolve discrepancies in expert interpretation of data (e.g., radiology reads).

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

This is not applicable. The document describes the performance of an electrosurgical device, not an AI-powered diagnostic or assistive tool for human readers. No MRMC study was conducted 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 an electrosurgical instrument used by a surgeon, not a standalone algorithm. Its performance inherently involves human-in-the-loop operation.

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

The "ground truth" for the performance studies appears to be based on:

Objective physical measurements: Energy output, mechanical strength, durability, electrical safety, burst pressures of sealed vessels.
Histopathological assessment: Evaluation of thermal damage in tissue, and chronic hemostasis in the animal studies.
Comparative performance: Against a legally marketed predicate device to establish "substantial equivalence."

8. The sample size for the training set

This is not applicable. The document describes a physical medical device (electrosurgical generator and sealer-divider), not a machine learning or AI model that requires a "training set."

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

This is not applicable for the reasons stated in point 8.

Intended Use:

The Voyant electrosurgical generator is indicated for use with Voyant devices in open and laparoscopic surgical procedures where the electrosurgical ligation of vessels or tissue bundles is desired.

The device can seal and divide vessels up to and including 7mm in diameter and tissue bundles that can be captured in the jaws of the device.

The device has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.

Summary of Technological Characteristics between Subject and Predicate:

The subject and predicate generators are technologically similar in that both are electrically isolated, microprocessor controlled, tabletop RF power supplies designed for use in electrosurgery. The generators are designed to provide RF energy to connected bipolar instruments with fuse energy modes. Both generators are equipped with a graphical user interface that allows the user to adjust the energy output settings. The generators are dissimilar in that the predicate generator supports electrosurgical cutting and coagulation as well as monopolar and standard bipolar instruments, where the subject device does not.

The subject and predicate instruments are technologically similar in size, configuration, and operation. They are designed to deliver RF energy to vessels up to 7mm and tissue captured between the jaws of the device for tissue fusion. Both instruments feature pistol-grip style handles with a trigger for jaw closure and button on the back of the handle for energy activation. The instruments are equipped with a mechanical, user-actuated blade for the division of sealed tissue. The instruments are dissimilar in that the subject jaws are capable of uninterrupted 360° rotation where the predicate jaws have 159° of rotation.

Discussion of Performance Testing Submitted:

Testing was performed on the subject Voyant® system to demonstrate electrical, mechanical and functional capabilities in accordance with IEC 60601-1-2 and IEC 60601-2-2. The subject system was also tested side-by-side against the predicate system to evaluate substantial equivalence with respect to performance in a laboratory setting as well as an animal model. Side-by-side testing focused on the seal quality evaluation and the local tissue effects of the applied RF energy in and surrounding the seal.

Non-clinical: Basic mechanical and functional capabilities were tested for the subject electrosurgical generator and subject sealer-divider. The following is a summary of components and testing performed:
