The Viora V20 system is intended for dermatological procedures.
The V-ST Handpiece is indicated for the temporary relief of minor muscle aches and pain, temporary relief of muscle spasm, and temporary improvement of local blood circulation.
The V-IPL Handpiece with wavelengths 415-1200nm (with 5 different filters) is indicated for the treatment of: Moderate inflammatory acne vulgaris.
Benign pigmented epidermal lesions including dyschromia, hyperpigmentation, melasma, and ephelides (freckles). Cutaneous lesions including warts, scars and striae.
Benign cutaneous vascular lesions including port wine stains, hemangiomas, facial, truncal and leg telangiectasias, rosacea, erythema of rosacea, angiomas, poikiloderma of Civatte and venous malformations. Removal unwanted hair. It is also intended for permanent reduction in unwanted hair. Permanent hair reduction is defined as the long-term stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regimen.
The V-Form Handpiece (with BC and FC applicators) is indicated for delivering non thermal RF combined with massage: relief of minor muscle aches and pain, relief of muscle spasm, temporary improvement of local blood circulation and temporary reduction in the appearance of cellulite.
The Viora V20 system is a RF and IPL multi application platform with three available treatment Handpieces:
V-ST Handpiece - Bi polar radiofrequency (RF) Handpieces
V-IPL Handpiece - Intense Pulsed Light (IPL) Handpiece
V - Form Handpiece (with BC and FC applicators) - mechanical vacuum massage and Bi-polar radiofrequency (RF) Handpiece.
The Main Unit (console) provides the operational and safety function of the system. The operator can modify the treatment parameters to achieve specific tissue effects depending on individual patient's skin condition and anatomical structure. The Foot Switch is used for system activation.
The provided text does not contain acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML-driven medical device.
The document is a 510(k) premarket notification for the Viora V20 System, a multi-application RF and IPL device for dermatological procedures. It focuses on demonstrating substantial equivalence to previously cleared predicate devices, rather than presenting performance data from a new study against defined acceptance criteria.
Here's why the requested information cannot be extracted and what is described instead:
- Acceptance Criteria and Reported Device Performance: This document does not specify quantitative acceptance criteria (e.g., sensitivity, specificity, accuracy targets) or report corresponding performance metrics for a new study. Instead, it argues for substantial equivalence by stating that the current device has "the same technological characteristics and the same performance characteristics" as its predicate devices, or that "no new safety or efficacy issues can be raised."
- Sample Size and Data Provenance: No new study data is presented, so there is no mention of sample size for a test set or data provenance.
- Number and Qualifications of Experts: No experts were used to establish ground truth because no new clinical study data is presented for performance evaluation.
- Adjudication Method: Not applicable, as no new study requiring ground truth establishment is described.
- Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: Not applicable. This is a 510(k) for a physical medical device, not an AI/ML diagnostic or assistive tool that would typically involve human-in-the-loop studies.
- Standalone Performance: Not applicable. The device is a physical system (RF and IPL handpieces) and not an algorithm/software with standalone performance metrics in the typical AI sense.
- Type of Ground Truth: Not applicable, as no new performance study data is presented.
- Sample Size for Training Set: Not applicable. This refers to an AI/ML training set, which is not relevant to this device's submission type.
- How Ground Truth for Training Set was Established: Not applicable.
What the document does state regarding "proof" and "performance":
- Substantial Equivalence: The core argument is substantial equivalence to predicate devices (Viora V20 system K142093 and Viora V10 system K150035). The manufacturer asserts that the V20 system with the V-Form Handpiece is "exactly the same" or has "the same technological characteristics and the same performance characteristics" as the cleared predicate devices, thus raising "no new safety or efficacy issues."
- Bench Testing: "Bench testing demonstrated that the V20 system (with the V- Form Handpiece) is as safe and effective as the cleared predicate devices." However, specific numerical results or acceptance criteria for this bench testing are not provided in this summary.
- No Clinical Studies Required: "Since the technological parameters of the Viora V20 system with the V- Form Handpiece are well within the parameters of the previously cleared V20 and V10 systems, Viora believes that animal and clinical studies are not required to determine the safety and efficacy of the V20 system with the V- Form Handpiece." This explicitly states that no new clinical study (which would typically generate performance data against acceptance criteria) was conducted or deemed necessary for this submission.
- Compliance with Standards: The V20 system complies with several IEC standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2, IEC 60601-2-57), which demonstrate safety and essential performance through adherence to recognized international standards.
§ 878.4810 Laser surgical instrument for use in general and plastic surgery and in dermatology.
(a)
Identification. (1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.
(b)
Classification. (1) Class II.(2) Class I for special laser gas mixtures used as a lasing medium for this class of lasers. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in § 878.9.
