Intended Use

The LAPEX-2000 is indicated for adjunctive use in the temporary relief of hand and wrist pain associated with Carpal Tunnel Syndrome.

Device Description

The LAPEX-2000 is a low level laser therapy device.

AI/ML Overview

This 510(k) submission (K034009) for the LAPEX-2000 low-level laser therapy device asserts substantial equivalence to predicate devices rather than providing a new clinical study with defined acceptance criteria and performance metrics. Therefore, many of the requested details are not available.

Here's a breakdown based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

This information is not provided in the submission. The submission relies on demonstrating substantial equivalence to predicate devices, implying that if it is equivalent, it meets the inherent safety and effectiveness standards of those previously cleared devices. There are no explicit acceptance criteria or reported performance metrics (like sensitivity, specificity, or improvement effect size) for the LAPEX-2000 itself in this document.

The comparison table provided focuses on technical specifications and intended use to show similarity to predicate devices:

The conclusion states that the device is "as safe and effective as the predicate device" based on "bench, electrical safety, EMC, and user testing data," but the details of this testing (acceptance criteria, performance results) are not elaborated upon.

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

Not applicable/Not provided. This submission does not include a clinical study with a "test set" in the context of device performance metrics. The mention of "user testing" is too vague to determine sample size or data provenance. The focus is on demonstrating technical equivalence and shared intended use with existing devices.

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

Not applicable/Not provided. As there is no clinical study with a test set requiring ground truth establishment, this information is not relevant to this submission type.

4. Adjudication Method for the Test Set

Not applicable/Not provided. No clinical test set requiring adjudication is described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No. An MRMC study was not conducted or reported in this submission. The submission does not discuss human reader performance or AI assistance.

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

No. This device is a therapeutic laser, not an algorithm, so a standalone performance study in the context of AI is not relevant.

7. The Type of Ground Truth Used

Not applicable/Not provided. For a substantial equivalence claim, the "ground truth" is largely established by the regulatory clearance of the predicate devices for their indicated uses and the technical similarity of the new device. No specific ground truth type (like pathology or outcomes data) for a novel clinical study is detailed for the LAPEX-2000.

8. The Sample Size for the Training Set

Not applicable/Not provided. This device is hardware, not an AI/ML algorithm that requires a "training set."

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

Not applicable/Not provided. This information is not relevant for this type of device and submission.

§ 890.5500 Infrared lamp.

(a)
Identification. An infrared lamp is a device intended for medical purposes that emits energy at infrared frequencies (approximately 700 nanometers to 50,000 nanometers) to provide topical heating.(b)
Classification. Class II (special controls). The device, when it is an infrared therapeutic heating lamp, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 890.9.
