AI/ML Overview

The provided text describes the regulatory submission for the CoolSeal System, a set of electrosurgical devices. It focuses on demonstrating substantial equivalence to predicate devices rather than establishing novel safety and efficacy through strict acceptance criteria and a single, overarching study.

Therefore, the concept of a single "acceptance criteria" and a "study that proves the device meets the acceptance criteria" in the way one might evaluate a diagnostic AI system with specific performance metrics is not directly applicable here. Instead, a series of performance data and testing were conducted to show that the new device performs "as well as" or "equivalent to" the predicate devices.

However, I can interpret the request by outlining the types of performance tests conducted and the implied acceptance by demonstrating equivalence to existing, legally marketed devices.

Here's an attempt to structure the information based on your request, understanding that the context is a 510(k) submission for substantial equivalence:

Implied Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Implied by Equivalence to Predicate)	Reported Device Performance
CoolSeal™ Trinity:
Biocompatibility (ISO 10993-1:2018 adherence)	Conducted and in accordance with ISO 10993-1:2018.
Electrical Safety (ANSI/AAMI/ES 60601-1, IEC 60601-2-2)	Complies with relevant clauses of ANSI/AAMI/ES 60601-1:2005/(R)2012 and A1:2012 and IEC 60601-2-2:2017.
Electromagnetic Compatibility (IEC 60601-1-2)	Complies with IEC 60601-1-2:2014.

In-vivo Vessel Burst Pressure (Lymphatics)	Demonstrated equivalent bipolar electrosurgical vessel sealing performance to predicate device (LigaSure™ Maryland jaw Sealer/Divider) using lymphatics in a porcine model.
In-vivo Thermal Spread Comparison	Demonstrated the subject device is as safe and effective as the predicate device by quantifying thermal spread in seals created by both devices in a porcine model (excision and 3D histological assessments).
Chronic Animal Study (Safety & Performance)	All animals (porcine model) survived 28 days post-op without complications. All vessel sealing effects maintained chronic hemostasis and healed as anticipated.
CoolSeal™ Mini:
Biocompatibility	Biocompatibility testing previously submitted for the predicate device (JustRight™ Sealer) is applicable, as design changes did not impact patient-contacting material.
Electrical Safety (ANSI/AAMI/ES 60601-1, IEC 60601-2-2)	Complies with relevant clauses of ANSI/AAMI/ES 60601-1:2005/(R)2012 and A1:2012 and IEC 60601-2-2:2017 (as part of the CoolSeal™ system).
Electromagnetic Compatibility (IEC 60601-1-2)	Complies with IEC 60601-1-2:2014 (as part of the CoolSeal™ system).
Mechanical and Functional Performance	Performed as expected (verified through testing).
Ex-vivo Vessel Burst Pressure	Demonstrated bipolar electrosurgical vessel sealing performance to predicate device (JustRight™ Sealer) using fresh excised porcine blood vessels. (The text doesn't explicitly state "equivalence" for the Mini's ex-vivo but implies it by stating it was to "demonstrate bipolar electrosurgical vessel sealing performance" in the context of substantial equivalence).
CoolSeal™ Generator:
Electrical Safety (ANSI/AAMI/ES 60601-1, IEC 60601-2-2)	Complies with relevant clauses of ANSI/AAMI/ES 60601-1:2005/(R)2012 and A1:2012 and IEC 60601-2-2:2017.
Electromagnetic Compatibility (IEC 60601-1-2)	Complies with IEC 60601-1-2:2014.
Mechanical and Functional Performance	Performed as expected (verified through testing).

Here are the answers to your specific questions based on the provided text, noting that much of this information is designed for software/AI device evaluation and not directly applicable to this hardware electrosurgical device submission:

A table of acceptance criteria and the reported device performance
- See table above. The "acceptance criteria" are implied by demonstrating substantial equivalence to predicate devices, and the "reported device performance" are the results of the various tests summarized in the "Performance Data" section.
Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- The text describes ex-vivo (fresh excised porcine blood vessels) and in-vivo (porcine model) testing.
- Specific sample sizes for these animal studies (e.g., number of vessels tested, number of animals) are not detailed in this summary.
- The provenance is non-human animal studies (porcine model). The country of origin of the data is not specified. All studies appear to be prospective animal studies, as they were conducted specifically for this submission.
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 question is not applicable to this type of device submission. Ground truth for an electrosurgical device's performance often relates to physical measurements (e.g., burst pressure, thermal spread histology) rather than expert interpretation of images. The evaluation likely involved veterinary and surgical experts for performing the animal studies and pathologists for histological assessments, but their numbers or specific qualifications are not mentioned.
Adjudication method (e.g. 2+1, 3+1, none) for the test set
- This is not applicable to this type of device submission. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in human-in-the-loop or diagnostic imaging studies when there are multiple expert opinions. Physical performance tests do not typically involve such adjudication.
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. This is an electrosurgical device, not a diagnostic imaging AI device that would involve human readers. Clinical studies (which might involve such comparative effectiveness) were explicitly stated as "not necessary to support this premarket notification."
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- This is not applicable in the context of an AI algorithm. For this device, "standalone performance" essentially refers to its performance in the ex-vivo and in-vivo tests, as described under "Performance Data." These tests evaluate the device's physical and functional characteristics.
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- For vessel burst pressure, the ground truth is a direct physical measurement.
- For thermal spread, the ground truth was established through histological assessments (pathology) performed on excised samples from the animal model.
- For the chronic animal study, the ground truth relates to observed biological outcomes (survival, presence/absence of complications, maintenance of hemostasis, healing as anticipated).
The sample size for the training set
- This is not applicable. This is a hardware electrosurgical device, not a machine learning model that requires a training set.
How the ground truth for the training set was established
- This is not applicable, as there is no training set for a machine learning model.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES

This premarket notification contains three major components that make up the CoolSeal™ vessel sealing system. The predicates identified in this submission were identified for each major component to better demonstrate substantial equivalence with similar performing components. These are as follows (Subject Device/Predicate Device):

· The CoolSeal™ Generator / The JustRight™ Generator both components are designed to provide lower power bipolar Radio Frequency (RF) energy to bipolar vessel sealing instruments for tissue-sealing applications. Both generators provide multiples signals (lights and tones) to users of the vessel sealing device related to the clinical function (e.g., seal complete, incomplete seal). The main difference between the subject device and the predicate device is the subject device has the ability to operate with multiple bipolar vessel sealing instruments. The subject device will automatically detect the compatible instrument and adjust the energy delivery algorithm accordingly. The predicate generator was only compatible with a single sealer.
· The CoolSeal™ Trinity / Ligasure™ Maryland jaw Sealer/Divider One-Step Sealing, Nano-Coated - both devices rely on the application of radio frequency (RF) energy to target tissue to create seals in the same sized structures (up to and including 7 mm in vasculature, tissue bundles, and lymphatics) interposed between the jaws of the instrument. At a high level, the subject device and predicate device is based on the following same technological elements:
- Jaws used to grasp, dissect, and manipulate tissue including sealing of intended o structures.
- Lever used to open and close the jaws. o
- Activation button allows the user to activate RF energy for sealing applications. O
- Cutting trigger allows the user to divide (cut) sealed structures O
- Shaft multiple shaft sizes available O

The following technological differences exist between the subject and predicate devices:

o Bilateral jaws
o Activation button is thumb activated vs lever activated
o Lower power output level required for sealing of structures
· The CoolSeal™ Mini / JustRight™ Sealer The CoolSeal™ Mini is the JustRight™ Sealer with some minor design modifications to enable its compatibility with the CoolSeal™ Generator. Excluding the following technological differences, the CoolSeal™ Mini is identical to the JustRight™ Sealer
- o Connector (plug) the connector was swapped out from the predicate device to enable compatibility with the CoolSeal™ Generator
- 0 Aesthetics non-patient contacting components were modified to reflect the new CoolSeal™ brand

{6}------------------------------------------------

PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

Biocompatibility Testing

CoolSeal™ Trinity:

The biocompatibility evaluation for the CoolSeal™ Trinity was conducted in accordance with ISO 10993-1:2018, Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process," as recognized by FDA.

CoolSeal™ Mini:

The design changes made to the predicate device to create the CoolSeal™ Mini does not impact any of the patient contacting material. Therefore, the Biocompatibility testing previously submitted for the predicate device is still applicable to the CoolSeal™ Mini.

Electrical Safety and Electromagnetic Compatibility (EMC)

The CoolSeal™ system complies with relevant clauses of the ANSI/AAMI/ES 60601-1:2005/(R)2012 and A1:2012 and IEC 60601-2-2:2017 standards for electrical safety and IEC 60601-1-2:2014 standard for EMC.

Mechanical and Functional Testing

Mechanical, electrical, and functional testing was carried out to verify that the proposed device performed as expected.

Ex-vivo and In-vivo Vessel Burst Pressure

CoolSeal™ Trinity:

Ex-vivo burst pressure testing of excised fresh porcine blood vessels was conducted on the subject device and predicate device to demonstrate equivalent bipolar electrosurgical vessel sealing performance. Additionally, in-vivo burst pressure testing of lymphatics was conducted on the subject device for comparison to the predicate to device to demonstrate equivalent bipolar electrosurgical vessel sealing performance.

CoolSeal™ Mini:

Ex-vivo burst pressure testing of excised fresh porcine blood vessels was conducted on the subject device and predicate device to demonstrate bipolar electrosurgical vessel sealing performance.

In-vivo Thermal Spread Comparison

CoolSeal™ Trinity:

Open laparotomy was performed in a porcine model using the subject device and predicate device. Each device was used to seal vessels and tissue bundles. Samples were excised for threedimensional histological assessments (e.g., length, width, and depth) to quantify thermal spread in seals created by both devices. This study demonstrated that the subject device is as safe and effective as the predicate device.

Chronic Animal Study

CoolSeal™ Trinity:

A chronic study was conducted to assess safety and performance of bipolar vessel sealing with the subject device over the course of 28 days. All animals survived 28 days post-op without any complications. All vessel sealing effects on tissue maintained chronic hemostasis and healed as anticipated.

Clinical Studies

Clinical data was not necessary to support this premarket notification as the indications for use, device technology, and mechanism of action is not significantly different when compared to the predicate devices. Furthermore, nonclinical testing as described above is sufficient to establish substantial equivalence.

CONCLUSIONS

Based on a review of bench top assessments, comparison of the device classification, intended use, operating principles, technological characteristics, sterility, and biocompatibility, the subject devices are safe, as effective, and performs as well as the legally marketed predicate devices.
