## Intended Use

The AtriCure Isolator Synergy Surgical Ablation System is intended to ablate cardiac tissue during surgery.

## Device Story

System comprises Ablation and Sensing Unit (ASU), Switch Matrix (ASB), footswitch, and single-patient use electrosurgical clamp. Clamp features opposing dual electrodes on insulated jaws; various lengths/curvatures available. Operator uses footswitch to trigger ASU, which delivers RF energy to electrodes to create transmural cardiac lesions. Used in surgical settings by clinicians. Device facilitates cardiac tissue ablation; modifications include overmolded end effector design. Benefits include precise, confined lesion creation during cardiac surgery.

## Clinical Evidence

Bench testing only. No clinical data presented. Biocompatibility testing (cytotoxicity, sensitization, irritation, acute systemic toxicity, material-mediated pyrogenicity) performed per ISO 10993-1. Performance testing confirmed transmurality and lesion width specifications remain consistent with the predicate.

## Technological Characteristics

Electrosurgical bipolar RF clamp. Materials: ABS resin (MG37EPX), Santoprene 8000 thermoplastic rubber, Ultem pins. Energy source: RF generator (ASU2/ASB3). Sterilization: Ethylene Oxide (EO) to 10^-6 SAL. Packaging: PETG blister with Tyvek lid. Complies with ISO 10993-1, IEC 60601-2-2, ASTM E1952-11, ISO 11607-2, AAMI TIR 28.

## Regulatory Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

Dear Jon McElwee:

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.

#### lll. Device Description

The AtriCure Isolator Synergy Surgical Ablation System is comprised of the Ablation and Sensing Unit (ASU), AtriCure Switch Matrix (ASB), an AtriCure Isolator Synergy device, and a footswitch. The AtriCure Isolator Synergy device is a single-patient use, electrosurgical instrument designed for use only with the ASU.

The AtriCure Isolator Synergy clamp is used for cardiac tissue ablation. When activated, the ASU delivers radiofrequency (RF) energy to the linear electrodes on the insulated jaws of the AtriCure Isolator Synergy Clamp. The Operator controls the application of this RF energy by pressing the Footswitch.

All AtriCure Isolator Synerqy devices are configured as vascular clamps and feature clamping jaws of various lengths, curvatures and apertures; rounded jaw tips, and cables that plugs into the ASB switch matrix and ASU RF generator.

The AtriCure Isolator Synergy Clamps features two pairs of opposing dual electrodes, an in-line handle with syringetype grip handle/ actuation and button release mechanisms.

There is a Glidepath™ Tape Guide that is a single-patient use, detachable, surgical device the guidance of surgical instruments through soft tissue during general surgical procedures. The Guide is package with ISOLATOR devices that have the Attachment Tip.

The Glidepath Tape Instrument Guide is a single-patient use, surgical device designed to facilitate the guidance of surgical instruments through soft tissue during general surgical procedures.

NOTE: Please refer to the AtriCure ASU2 and ASB3 Instructions for information specific to the ASU2 and ASB3.

### IV. Indications for Use

The AtriCure Isolator Synergy Surgical Ablation System is intended to ablate cardiac tissue during surgery.

### V. Comparison of Technological Characteristics (Isolator Synergy Clamp -K110117)

This submission included modifications to allow for an alternate end effector design change to an overmold configuration. The science and fundamental technology of the Isolator Synergy Clamps (EMR2) in comparison to the predicate Isolator Synergy Clamp (EMR2, EML2), cleared per K110117, remain the same. Performance testing confirmed that the Isolator Synergy Clamps meets the same requirements for safety and efficacy as the predicate Isolator Synergy Clamp.

### VI. Performance Data

A review of the risk analysis concluded there is not overall change to the risk profile of the proposed AtriCure Isolator Synergy clamps versus the previously cleared AtriCure Isolator Synergy clamps as the modifications to the proposed AtriCure Isolator Synergy do not add or remove any features of the device or change the clinical application.

The proposed changes do not include any change to design or performance specifications of the AtriCure Isolator Synergy clamps. Additionally, the proposed changes did not modify the intended use, therefore the previously submitted bench and animal data remain valid for the AtriCure Isolator Synergy clamps.

The following consensus standards were leveraged in this submission:

- ISO 10993-1
- IEC 60601-2-2
- . ASTM E1952-11
- ISO 11607-2
- AAMI TIR 28

### Biocompatibility Testing

The biocompatibility evaluation is in accordance with the International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process" as recognized by FDA. Data collected from the following tests support this change:

- Cytotoxicity
- Sensitization ●
- Irritation ●
- . Acute Systemic Toxicity
- . Material Mediated Pyrogenicity

### VII. Conclusions

AtriCure has demonstrated that the modifications made to the Isolator Synergy Clamp (EMR2, EML2) are substantially equivalent in intended use/indication for use as the previously cleared Isolator Synergy Clamp (EMR2, EML2) per K110117.
