Device Description

The Fotona LightWalker Laser System Family is based on Er:YAG (2940 nm) and Nd:YAG (1064 nm) laser technology. It combines two flashlamp-pumped laser sources in one housing, with optical cavities containing the Er:YAG and Nd:YAG crystals. A diode aiming beam is combined with both therapeutic laser beams. The combined therapeutic and aiming beams are guided through an articulated arm to an optical handpiece (in the case of the Er: YAG laser), or, in the case of the Nd:YAG laser, through an optical fiber delivery system to an optical handpiece or to the bare fiber distal end. The Er:YAG laser is intended to be used for incision/excision, cutting, ablation, vaporization and coagulation of soft and hard tissue in dentistry, dermatology and other surgical areas. The Nd:YAG laser is intended to be used for various intra oral treatments in dentistry, and for various surgical and aesthetic applications in dermatology and other surgical areas.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the Fotona LightWalker Laser System Family, which is a medical laser system. The document focuses on establishing substantial equivalence to predicate devices and does not detail specific acceptance criteria or a study that evaluates the device's performance against such criteria in the context of clinical outcomes or diagnostic accuracy. Instead, the "acceptance criteria" discussed are related to regulatory compliance and safety standards, and the "study" is a non-clinical summary of verification and validation tests.

Therefore, the requested information elements related to device performance (e.g., accuracy, sensitivity, specificity), ground truth, sample sizes for test and training sets, expert qualifications, adjudication methods, and MRMC studies are not applicable to this document as it does not present a clinical performance study of this nature.

Here's the information that can be extracted based on the provided text, primarily focusing on the regulatory and technical aspects:

1. Table of Acceptance Criteria and Reported Device Performance

As this document does not present a clinical performance study with acceptance criteria for metric-based performance (e.g., sensitivity, specificity, accuracy), the "acceptance criteria" here refer to compliance with safety and performance standards. The "reported device performance" refers to the device meeting these standards.

Substantial Equivalence to Predicate DevicesThe device's indications for use and technological characteristics do not raise new types of questions regarding safety and efficacy when compared to the predicates.

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

  • Not Applicable. The document describes a substantial equivalence submission based on non-clinical testing and comparison to predicate devices, not a clinical study with a "test set" of patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Not Applicable. No experts were used to establish ground truth for a clinical test set as no such study is described.

4. Adjudication method for the test set:

  • Not Applicable. No test set or related adjudication process is described.

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. No MRMC study or AI component is mentioned. This is a laser device cleared for surgical procedures.

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

  • Not Applicable. This device is a laser system, not an algorithm. Its operation inherently involves a human operator and it does not have "standalone" performance in the context of an algorithm.

7. The type of ground truth used:

  • Not Applicable. The "ground truth" for this regulatory submission is compliance with established safety and performance standards for medical devices and establishing substantial equivalence based on technical characteristics and intended use. No clinical ground truth (e.g., pathology, outcomes data) is presented in this document.

8. The sample size for the training set:

  • Not Applicable. This document does not describe a machine learning algorithm or a training set.

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

  • Not Applicable. This document does not describe a machine learning algorithm or a training set.
