AI/ML Overview

The provided text is a 510(k) summary for the DC 7 Diode Laser Therapy System. It describes the device, its intended use, and compares it to predicate devices to establish substantial equivalence.

Based on the document, here's an analysis of the acceptance criteria and study information:

Acceptance Criteria and Device Performance

The DC 7 device is a diode laser therapy system. The acceptance criteria are based on substantial equivalence to predicate devices rather than meeting specific performance metrics in a clinical study. The device meets "acceptance criteria" by demonstrating that its technical and functional characteristics are either identical or sufficiently similar to legally marketed predicate devices, and that any differences do not raise new questions of safety or effectiveness.

Table of Acceptance Criteria (based on comparison to predicate devices) and Reported Device Performance (DC 7):

Study Details

The provided document (510(k) summary) explicitly states:

  • Non clinical Performance Data: None
  • Clinical Performance Data: None

This means that a traditional "study" to prove the device meets acceptance criteria in terms of performance was not performed in the context of this 510(k) submission. Instead, the "study" demonstrating that the device meets criteria is a comparative analysis proving substantial equivalence to predicate devices, which is sufficient for 510(k) clearance for this type of device.

Given the absence of clinical/non-clinical performance data, the following points cannot be addressed as no such studies were conducted or presented in this summary:

  1. Sample size used for the test set and the data provenance: Not applicable, as no test set data from performance studies were provided. The "test set" here would implicitly be the specifications of the predicate devices.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for device performance was not established via expert review in this submission.
  3. Adjudication method for the test set: Not applicable.
  4. 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 surgical laser, not an AI-assisted diagnostic tool.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is a surgical laser.
  6. The type of ground truth used: For the purpose of this 510(k), the "ground truth" for proving substantial equivalence comes from the established safety and effectiveness of the legally marketed predicate devices, against which the DC 7's technical specifications are compared.
  7. The sample size for the training set: Not applicable, as this is not an AI/machine learning device.
  8. How the ground truth for the training set was established: Not applicable.

In summary, the clearance for the DC 7 is based on a demonstration of substantial equivalence to predicate devices through a detailed comparison of technical specifications, rather than new performance studies with specific acceptance criteria that would typically involve test sets, expert ground truth, or statistical analysis of clinical outcomes.

The pulse duration of laser should be shorter than thermal relax time of target tissues so that the thermal diffusion willnot act on the surrounding tissues during the heating process of the target tissues, in this way the surrounding tissuescan be protected. The comparatively short pulse duration of DC7 will not introduce any problems regarding the safetyand effectiveness of the device. In addition, the shorter pulse duration will decrease the injury which the laser beambring to the normal tissue, at the same time the shorter pulse duration will reduce the smoke caused by treatment, thencorrespondingly optimize the vision during the treatment also.
