Device Description

The Ceralas D1950 is a diode laser operating at 1950nm with a maximum power output of 50W.

AI/ML Overview

This 510(k) summary describes a medical device, the Biolitec Inc.'s 50W Ceralas Diode 1950nm Laser System (Model D1950), which is a surgical diode laser. The provided document details its intended uses and compares its performance to a predicate device for substantial equivalence.

Here's an analysis based on your request:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in the typical quantitative sense (e.g., a specific numerical threshold for accuracy or a statistical measure). Instead, the acceptance criterion for regulatory clearance appears to be "substantially equivalent performance" to a legally marketed predicate device.

Acceptance Criteria (Implicit)Reported Device Performance
Substantially equivalent vaporization rates to predicate 2010nm laserBench testing demonstrated substantially equivalent performance on potato slices and porcine muscle tissue.
Substantially equivalent cutting rates to predicate 2010nm laserBench testing demonstrated substantially equivalent performance on porcine liver, skin, and muscle tissue.
Substantially equivalent coagulation rates to predicate 2010nm laserBench testing demonstrated substantially equivalent performance on porcine liver, skin, and muscle tissue.
Similar tissue effects to predicate 2010nm laserTesting demonstrated similar tissue effects between the Ceralas D1950 and the 2010nm laser.
Same intended uses and indications as predicate devicesStated in the "Substantial Equivalence" section.
Similar technological characteristics as predicate devicesStated in the "Substantial Equivalence" section.
Similar principles of operation as predicate devicesStated in the "Substantial Equivalence" section.

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

  • Sample Size: The document does not specify a numerical sample size (e.g., number of potato slices, porcine muscle tissue samples, or individual tests). It states "potato slices and porcine muscle tissue" and "porcine liver, skin, and muscle tissue." This suggests an experimental setup but lacks quantification of samples.
  • Data Provenance: The data provenance is generally "bench testing." There is no mention of country of origin for the data or whether it was retrospective or prospective. Given it is bench testing, it would inherently be prospective for the purpose of the 510(k) submission.

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

This type of information is not applicable to the provided document. The study involved bench testing on inanimate and animal tissue to assess physical effects (vaporization, cutting, coagulation), not a clinical assessment requiring expert interpretation of ground truth in the human diagnostic context.

4. Adjudication Method for the Test Set

This information is not applicable. As a bench test comparing physical effects, there is no "adjudication method" in the sense of resolving discrepancies between human readers or experts. The comparison was based on performance and observed tissue effects, presumably by the researchers conducting the bench tests.

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

No. A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This study is an engineering bench test comparing a new laser system to a predicate laser system based on their physical interaction with tissue, not on diagnostic accuracy with human readers or AI.

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

No. This question is not applicable. The device is a surgical laser, not an AI algorithm. The performance evaluation was for the laser's physical capabilities (vaporization, cutting, coagulation) in a standalone manner (without a human in the loop for the performance measurement itself), but it's not an "algorithm" in the typical sense this question implies for AI/diagnostic devices.

7. The Type of Ground Truth Used

The "ground truth" for this study was the directly observed physical effects (vaporization, cutting, coagulation rates, and overall tissue effects) of the laser on standardized biological and non-biological materials (potato slices, porcine muscle, liver, and skin). The predicate device's performance served as the benchmark for "substantially equivalent" ground truth.

8. The Sample Size for the Training Set

Not applicable. This product is a physical laser device, not a machine learning or AI algorithm that requires a "training set."

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

Not applicable. As there is no training set for this type of device, no ground truth was established for a training set.
