Device Description

The Cynosure TempSure™ System is a radiofrequency generator with a variety of applications both aesthetic and electrosurgical procedures. The intended action is achieved through application of radiofrequency energy to the patient which results in minimization of heat dissipation and cellular alteration. Output of energy is controlled via the guided user interface (GUI) and the foot and/or hand-switch. The TempSure™ system is intended for non-ablative treatment of mild to moderate facial wrinkles and rhytids, heating for the purpose of elevating tissue temperature for selected medical conditions, and hemostasis/coagulation for general surgery applications. The generator is used with a temperature sensitive handpiece for aesthetic procedures that provides real-time temperature feedback. This temperature information is displayed on the user interface that shows the temperature set point and actual tissue temperature along with procedure time, system error, and warning codes. A thermistor protrudes at the end of the temperature-sensitive handpiece at the point of patient contact, which provides a constant information feedback loop as to the tissue temperature throughout a procedure.

1. Table of Acceptance Criteria and Reported Device Performance

Performance MetricAcceptance CriteriaReported Device Performance
Temperature Monitoring AccuracyEquivalent to Fluke Infrared Thermometer (+/- 1.5°C margin for external temperature measurement tools). Ability to maintain desired temperature throughout treatment.Average difference in temperature between the FLIR camera and the Portrait handpiece was +/- 1.5°C, demonstrating equivalence to the Fluke Infrared Thermometer. The device maintained the desired temperature throughout the treatment with no adverse events.
Thermal Effects on Tissue (TAZ)Thermally Affected Zone (TAZ) should be similar to the predicate device (ForceTriad).When comparing the TAZ of the TempSure to the ForceTriad on ex-vivo tissue, two of the three power bars showed overlapping results for each point, indicating similar TAZs. This was deemed substantially equivalent despite differences in maximum output power.
Electrical SafetyCompliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2.The device demonstrated compliance with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2.
Electromagnetic Compatibility (EMC)Compliance with IEC 60601-1-2.The device demonstrated compliance with IEC 60601-1-2.
Safety and EffectivenessGeneral safety and effectiveness equivalent to legally marketed predicate devices.Nonclinical tests demonstrated the TempSure electrosurgical generator is safe and effective and performs as well as or better than the legally marketed predicate devices. The device meets design specifications and performance requirements.

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

  • Temperature Monitoring Test: "three different power settings in various treatment areas on two subjects." The data provenance is not explicitly stated (e.g., country of origin, retrospective/prospective).
  • Thermal Effects on Tissue Test: "performed using both devices in triplicate on three tissue samples (liver, kidney, and muscle), and three power settings." These were ex-vivo tissue samples.

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

The document does not mention the use of experts to establish ground truth for the test set. The validation relies on objective measurements against a reference device (FLIR Thermal Camera) or comparative measurements between devices on physical tissue samples.

4. Adjudication Method for the Test Set

No adjudication method is described, as the evaluation methods relied on direct measurements or comparisons rather than expert interpretation.

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

No, an MRMC comparative effectiveness study was not done. The studies described are technical performance tests and ex-vivo tissue comparisons, not studies involving human readers.

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

This device, "TempSure," is an electrosurgical generator and not an AI or algorithm-driven diagnostic device. Therefore, the concept of a "standalone (algorithm only without human-in-the-loop performance)" study does not apply. The device's performance is tested directly.

7. The Type of Ground Truth Used

  • Temperature Monitoring Test: The ground truth was established by direct physical measurement using a FLIR Thermal Camera, which served as the reference standard for temperature.
  • Thermal Effects on Tissue Test: The ground truth for the thermally affected zone (TAZ) was established by measurements using Image-J on ex-vivo tissue samples, comparing the output of the TempSure to the predicate device (ForceTriad).

8. The Sample Size for the Training Set

The document does not describe any machine learning or AI components for which a "training set" would be applicable. The TempSure is a radiofrequency generator, and its validation relies on traditional engineering and medical device performance testing, not AI model training.

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

As no training set is described or implied, this point is not applicable.

{5}------------------------------------------------

The following non-clinical tests have been included in this 510k submission in determination of substantial equivalence between the test device and the referenced predicates. These tests have been conducted in accordance with the FDA Guidance "Premarket Notification 510k Submissions for electrosurgical Devices for General Surgery' - Section XI. Performance Data. See Section 18 -Performance Testing, Bench. A brief summary is provided below.

Temperature Monitoring Test

The TempSure with Portrait handpieces was used at three different power settings in various treatment areas on two subjects. The FLIR Thermal Camera was used during the treatment to measure the temperature of the subjects' skin in two minute intervals over the 10 minute total treatment time. The temperature measurements of the Portrait handpieces were compared to those of the FLIR. For each treatment, the average difference in temperature between the FLIR and Portrait handpiece was +/-1.5℃. This +/- 1.5°C margin is equivalent to that of the Fluke Infrared Thermometer, which is used as the external temperature measurement tool for the device's predicates. This test proves that the TempSure with Portrait handpieces has the same temperature measurement capabilities of the Surgitron with GlideSafe or PelleFirm handpieces. In addition, this bench test proved that the TempSure with Portrait handpieces can maintain the desired temperature throughout the treatment and there were no adverse events.

Thermal Effects on Tissue Test

Testing was performed on ex-vivo tissue samples to compare the thermally affected zone (TAZ) of the TempSure and predicate device ForceTriad. Testing was performed using both devices in triplicate on three tissue samples (liver, kidney, and muscle), and three power settings. The depth and lateral TAZ measurements were recorded using Image-J. For each tissue and power setting combination, the TAZ created by the ForceTriad and TempSure were compared. Two of the three power bars for overlapping for each point, which shows that the TAZs were similar. This test shows that the TempSure is substantially equivalent to the ForceTriad device, despite the variation in maximum output power.

Electromagnetic Compatibility and Electrical Safety

Electrical safety testing for the Cynosure TempSure was also completed to prove the safe use of the device. These test reports are provided in accordance with FDA Guidance "Premarket Notification 510k Submissions for Electrosurgical Devices for General Surgery' - Section XII - Electrical Safety and Electromagnetic Compatibility". As per the guidance, endoscopic instruments also require compliance with IEC 60601-2-18. The TempSure is not an endoscopic/laparoscopic instrument, and therefore testing to IEC 60601-2-18 is not needed. The following test reports are available in Section 17 -Electromagnetic Compatibility and Electrical Safety.

  • IEC 60601-1, Medical Electrical Equipment Part 1: General requirements for basic safety and . essential performances
  • . IEC 60601-1-2. Medical Electrical Equipment - Part 1 -2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic disturbances - requirements and tests
  • IEC 60601-2-2, Medical electrical equipment Part 2 -2: Particular requirements for the basic . safety and essential performance of high frequency surgical equipment and high frequency surgical accessories

807.92(b)(2) Clinical tests submitted – N/A - No clinical tests submitted

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

807.92(b)(3) Conclusions drawn from clinical and non-clinical tests submitted

The nonclinical tests demonstrate that the TempSure™ electrosurgical generator safe and effective and performs as well as or better than the legally marketed predicate devices. The Temperature Monitoring test demonstrated that the temperature sensing feature worked as intended under clinical conditions at multiple temperature settings and handpiece sizes. The device was able to accurately read the temperature of the skin as similar to the Fluke used with the predicate device. It was also able to maintain the desired temperature throughout a treatment with no adverse events. The Thermal Effects on Tissue test showed that the thermally affected zone created by the TempSure™ device was similar to that created by the predicate device ForceTriad in ex-vivo tissue testing. Despite their difference in maximum output power, the devices created a similar TAZ and therefore the devices can be considered substantially equivalent. In addition, the Electromagnetic Compatibility and Electrical Safety testing shows that the device is safe to use and meets required standards. These non-clinical tests show that the TempSure™ generator can safely deliver RF energy to the patient as intended. The device meets design specifications as well as performance requirements.
