Device Description

The Fotona Dynamis Pro Laser System Family is based on Er:YAG (2940 nm) and Nd:YAG (1064 nm) laser technology. The laser unit and controls are contained in a single console. Electrical power is supplied to the console by the facility's power source. The unit combines two flashlamp-pumped laser sources in one housing, with optical cavities containing the Er: YAG and Nd: YAG crystals. A red diode aiming beam (650 nm) is combined with both therapeutic laser beams. The combined therapeutic and aiming beams are guided through an articulated arm to an optical manual or scanner hand piece (in the case of the Er: YAG laser), or through an optical fiber delivery system to an optical manual or scanner handpiece (in the case of the Nd: Y AG laser). Optionally, the Nd: YAG therapeutic and aiming laser beams can be guided through a fiber having a connector on the proximal end and a bare fiber on the distal end. Fotona's power supply Variable Square Pulse (VSP) Technology, integrated into the laser system, allows control of the laser energy and the laser pulse duration. The user activates laser emission by means of a footswitch.

The Fotona Dynamis Pro Family is designed to operate in single wavelength (Nd:Y AG or Er: Y AG) configurations (models) and dual wavelength (Nd: Y AG and Er: Y AG) configurations (models).

AI/ML Overview

The provided document describes the Fotona Dynamis Pro Family laser system, a medical device for surgical procedures. It seeks to establish substantial equivalence to previously cleared predicate devices rather than present a study with specific acceptance criteria and performance data for a new, AI-driven diagnostic or prognostic device.

Therefore, the requested information for acceptance criteria and a study proving device performance (including sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, and training set details) is not directly available in this document. This document is a 510(k) premarket notification for a laser surgical instrument, which typically relies on demonstrating that the new device has the same intended use and technological characteristics as a legally marketed predicate device, rather than requiring extensive clinical performance studies with acceptance criteria in the way an AI diagnostic tool would.

Here's a breakdown of what can be extracted or inferred based on the document's nature:

1. A table of acceptance criteria and the reported device performance:

This document does not present specific acceptance criteria in the context of diagnostic performance (e.g., sensitivity, specificity, AUC) or a detailed clinical study comparing the device to a gold standard with predefined thresholds. Instead, the "acceptance criteria" are implied by substantial equivalence to predicate devices. The "reported device performance" is largely framed by its technical specifications matching or being similar to those of its predicates for similar intended uses.

Safety and Performance Standards Compliance:The device is designed, tested, and will be manufactured in accordance with listed mandatory and voluntary standards (e.g., IEC 60601-1, IEC 60601-2-22, IEC 60825-1, EN ISO 14971, IEC 62304, ISO 17664, IEC 62366, IEC 60601-1-6).
Functional Equivalence:The device is stated to be "substantially equivalent in terms of indications for use and technology based on technical characteristics" to the listed predicate devices. The risk and benefits are also stated to be "identical to the predicate devices when used for similar clinical applications."

No specific study with acceptance criteria for diagnostic/AI performance is described. The "study" mentioned is laboratory testing to validate and verify that the proposed device meets design specifications and is substantially equivalent to predicate devices. This type of testing focuses on engineering performance and safety, not clinical efficacy in a comparative AI context.

2. Sample size used for the test set and the data provenance:

  • Not applicable. This isn't a diagnostic device using a test set of patient data. The "testing" involved laboratory verification and validation against design specifications and relevant standards.

3. 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):

  • Not applicable. No ground truth for a test set of patient data was established or used as this is a surgical laser device not an AI diagnostic tool.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

  • Not applicable. No test set requiring expert adjudication was used.

5. 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:

  • Not applicable. This device is a laser surgical instrument, not an AI-assisted diagnostic tool. No human reader performance, with or without AI, is relevant to its substantial equivalence determination.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:

  • Not applicable. This device is hardware (a laser system), not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

  • Not applicable. For this type of device, the "ground truth" relates to its adherence to technical specifications, safety standards, and functional equivalence to its predicate devices, rather than a clinical ground truth like pathology or outcomes data in the context of an AI diagnostic study.

8. The sample size for the training set:

  • Not applicable. This is not an AI/machine learning device that requires a training set.

9. How the ground truth for the training set was established:

  • Not applicable. No training set was used.
