The Venus Legacy CX device is intended for the treatment of the following medical conditions; using the LB2 and LF2 applicators for delivery of non-thermal RF combined with massage and magnetic field pulses:

Relief of minor muscle aches and pain, relief of muscle spasm .
Temporary improvement of local blood circulation .
Temporary reduction in the appearance of cellulite

Device Description

The Venus Legacy CX device consists of a console (main unit) and two applicators (LB2, LF2). The console in the Venus Legacy CX device contains a power supply unit, an RF generator (power module, on main board), a suction module (vacuum), a controller unit (on main board) and a touchscreen user interface and display panel. The Venus Legacy CX device provides RF treatments combined with emitted magnetic fields and vacuum massaging. The Vacuum is mainly used for the massaging of deep tissues by creating mild to deep suction. The vacuum massage contributes to the sub-dermal and adipose tissues shrinkage and improves the contact surface between electrodes and tissue. The RF currents heat the adipose and muscular tissues to trigger tissue level changes leading to temporary reduction in the appearance of cellulite and temporary relief of muscle pain and muscle spasm. The RF heating effect also improves local blood circulation in the sub dermal layers. The PMF assists in achieving treatment effect.

AI/ML Overview

This document, a 510(k) summary for the Venus Legacy CX device, primarily focuses on demonstrating substantial equivalence to a predicate device (Viora Reaction System) rather than proving the device meets specific performance acceptance criteria through clinical studies with human participants. Therefore, many of the requested categories related to clinical study design, sample sizes, expert adjudication, and comparative effectiveness studies are not applicable or cannot be extracted from this document directly.

The document emphasizes performance bench testing to show similarity to the predicate device.

Here's the information that can be extracted, and an explanation for the areas where information is not available:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) summary demonstrating substantial equivalence, explicit "acceptance criteria" for clinical performance (e.g., specific percentages of cellulite reduction in a defined population) are not provided. Instead, the "performance" discussed is related to engineering and bench testing comparisons to the predicate.

Acceptance Criteria (Implied by Substantial Equivalence Goal)	Reported Device Performance (as demonstrated by bench tests)
RF Output Specifications (Similar to predicate)	Equivalent RF output specifications compared to the predicate Viora Reaction device.
Thermal Profile (Similar to predicate in porcine tissue)	Very similar thermal profile to the Viora Reaction predicate across multiple assessments in porcine tissue.
Electrical Safety (Compliance with standards)	Passed AAMI/ANSI ES60601-1, IEC 60601-1-2, and IEC 60601-2-2.
Electromagnetic Compatibility (Compliance with standards)	Passed IEC 60601-1-2.
Software Functionality (Performs as intended)	Software verification and validation testing demonstrated the system performed as intended.
Cleaning and Disinfection Effectiveness (Passing results)	Validation study of cleaning and disinfection instructions for applicators yielded passing results.
Biocompatibility (Safe tissue contact materials)	Established based on prior clearance of Venus Freeze (MP)2 device (K111660) which uses same tissue-contacting materials. Additionally, applicator plastic material tested positive in Cytotoxicity (ISO 10993-5), Intracutaneous (ISO 10993-10), and Guinea Pig Maximization Sensitization (ISO 10993-10) testing.

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

Test Set (Clinical): Not applicable. This document does not describe a clinical test set with human participants.
Test Set (Bench/Pre-clinical):
- Porcine Tissue for Thermal Profile: The document mentions "porcine tissue" but does not specify the sample size (e.g., number of tissue samples or animals).
- Other Bench Tests: No specific sample sizes for components or systems tested are provided, other than "several performance tests" and "validation study."
Data Provenance: Not specified, but generally, bench testing data would be generated in a lab setting, likely in the country of manufacture (e.g., USA or where Venus Concept operates). The testing is prospective for the purpose of this 510(k).

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

Not applicable. No clinical ground truth established by experts is mentioned as this is a 510(k) based on substantial equivalence using bench testing.

4. Adjudication Method for the Test Set

Not applicable. No clinical test set with expert adjudication is described in this document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

No. This document does not mention an MRMC comparative effectiveness study, as it relies on substantial equivalence through bench testing.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable. This device is a physical medical device (electrosurgical unit) and not an AI algorithm. Its performance is inherent to the device's physical operation, not an algorithm's standalone output.

7. The Type of Ground Truth Used

For Bench Testing: The "ground truth" for the bench testing would be established by objective measurements and comparisons against the specifications of the predicate device and relevant international standards (e.g., RF output, thermal profiles, electrical safety standards).
For Biocompatibility: Ground truth involved established ISO standards for cytotoxicity, intracutaneous testing, and sensitization, along with previous clearance of an equivalent device.

8. The Sample Size for the Training Set

Not applicable. This device is not an AI algorithm that requires a training set.

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

Not applicable. This device is not an AI algorithm that requires a training set.

muscle pain and muscle spasm. The RF heating effect also improves local blood circulation in the sub dermal layers. The PMF assists in achieving treatment effect.

Technological Characteristics:

The Venus Legacy CX Device has similar technological characteristics to the Viora Reaction device, as both use RF energy and mechanical manipulation to achieve the same intended use. The design and components of the Venus Legacy CX device, including the console (with power supply, RF generator, suction module, main CPU and display panel) and the applicators (with cable, connector to console, and vacuum pump) are similar to those of the predicate Viora Reaction device. The differences in the design and configuration of the applicators, as well as the additional PMF energy source in the Venus Legacy CX device, do not influence the core technology to achieve the indicated effects. As demonstrated in the bench tests, the performance specifications (including frequency, RF electrical power, and vacuum power) of the Venus Legacy CX device are substantially equivalent to those of the Viora Reaction device. Patient contact materials are also similar. Furthermore, the Venus Legacy CX device underwent performance testing, including RF output and thermal profile testing, software validation testing, electrical safety testing to AAMI/ANSI ES 60601-1, and electromagnetic compatibility testing according to IEC 60601-1-2. These performance tests demonstrated that the minor differences in the technological characteristics between the subject and predicate devices do not raise new types of safety or effectiveness concerns.

. Cleaning and Disinfection Testing: A validation study of the cleaning and disinfection instructions for the Legacy CX applicators was conducted, and all results were passing.
. Biocompatibility: The biocompatibility of the device was established based on the prior clearance of the company's Venus Freeze (MP)2 device (K111670), which has the same tissue contacting materials for the same type of patient contact. In addition, the applicator plastic material was demonstrated to be biocompatible in Cytotoxicity testing (ISO 10993-5); Intracutaneous testing (ISO 10993-10); and Guinea Pig Maximization Sensitization testing (ISO 10993-10).

These performance tests demonstrated that the device meets the system requirements and do not raise new types of safety or effectiveness concerns.

Substantial Equivalence:

The Venus Legacy CX Device has the same intended use and similar indications for use, technological characteristics, and principles of operation as its predicate device. The minor technological differences between the Venus Legacy CX device and its predicate device do not raise any new issues of safety or effectiveness. The Venus Legacy CX device and the Viora Reaction device are based on the same core technology of RF heating and vacuum massaging for the same indications for use. The design and components in the Venus Legacy CX device, including the console and the applicators are similar to the design and components found in the predicate Viora Reaction device. The minor technological differences, including some differences in device design and the addition of the PMF energy source in the Venus Legacy CX device, do not alter device core technology or performance. The performance of the Venus Legacy CX device is substantially equivalent to that of the Viora Reaction device, as demonstrated in testing.

Conclusions:

Therefore, based on the same intended use and similar indications for use, technological characteristics, and principles of operation, the Venus Legacy CX device is substantially equivalent to the Viora Reaction predicate device.
