Lumenis AcuPulse W CO2 Laser System, Delivery Devices and Accessories is indicated for incision, ablation, vaporization and coagulation of body soft tissues in medical specialties including aesthetic (dermatology and plastic surgery), podiatry, otolaryngology (ENT), gynaecology, neurosurgery, orthopaedics, general and thoracic surgery. The use with the scanning unit is indicated for ablative skin resurfacing.

The AcuPulse W system (recently cleared under K201663) is a scaled-down version of the cleared Lumenis Family of AcuPulse CO2Laser System. Delivery Devices and Accessories under K180597. The modified AcuPulse W, identically to its predicate (K201663) is comprised of the following main functional components:

• A Laser Console with a Free Beam Port to which an articulated arm is attached .
• . A footswitch to activate the laser treatment beam and allow the selected laser energy to be transmitted via the delivery device to the target location.
• . A variety of Free Beam Delivery Device and accessories
  The modified AcuPulse W and the cleared AcuPulse W (K201663) systems have the same proprietary software, which is embedded in the Main Controller, Peripheral Controller units and PC. Importantly, both systems use the same Software version, which was already validated, verified and submitted under K201663. Also, no changes to the Hardware were made to the svstem.
  The AcuPulse W is offered with previously cleared AcuPulse Handpieces/Tips that connect to the articulated arm or/and scanners for controlled delivery of laser energy to the target tissue. Among them, the cleared 90° Side-firing Handpiece (K201663) connects to the AcuScan 120 Microscanner through two adaptors (a Handpiece Adapter and Third Lens Adapter) for delivery of laser energy. The 90° Side-firing Handpiece is comprised of the following components:
• . Handpiece Adapter (cleared under K201663)
• . Tip:
  • Multiuse Standard Focus Tip (cleared under K201663) o
  • Multiuse Fine Focus Tip (cleared under (K201663) о
  • Disposable Standard Focus Tip (subject of this submission) o
  • Disposable Fine Focus Tip ((subject of this submission) o
• . Limiter ring (cleared under K201663)
  In this submission, Lumenis is introducing a disposable configuration of the 90° Side-firing Handpiece Tips in addition to the already cleared multiuse tips to respond to the increased market demand of disposable accessories for reducing the occurrence of treatment acquired infections. These 90° Side-firing Handpiece disposable tips are single use tips, packaged and EO sterilized, similarly to Lumenis devices previously cleared and used with the cleared AcuPulse Family of CO2Lasers (K100384 and K130164).

The provided document describes a 510(k) premarket notification for a medical device, specifically the Lumenis AcuPulse W CO2 Laser System, Delivery Devices, and Accessories. This document is a regulatory submission to the FDA, asserting substantial equivalence to a legally marketed predicate device.

It does not contain information about the performance of an AI/algorithm-driven device, nor does it provide acceptance criteria or study results for such a device. The modifications detailed in this 510(k) are related to the introduction of disposable tips for a laser system, which is a hardware change, not an AI software change.

Therefore, I cannot fulfill your request for:

1. A table of acceptance criteria and reported device performance.
2. Sample sizes or data provenance for a test set.
3. Number and qualifications of experts for ground truth establishment.
4. Adjudication methods.
5. MRMC comparative effectiveness study results.
6. Standalone algorithm performance.
7. Type of ground truth used.
8. Sample size for the training set.
9. How ground truth for the training set was established.

The document discusses design verification processes for the modified laser system and its disposable tips, which include:

• Risk analysis per ISO 14971.
• Electrical safety testing to IEC 60601-1.
• Performance verification and validation to evaluate that the 90° Side-firing Handpiece with the new disposable configuration of Tips performs according to its specifications.
• EO sterilization and Shelf-life validation activities (ISO 11607, ISO 11135-1, ISO 10993).
• Biocompatibility evaluation (ISO 10993).

The key takeaway from the document regarding "performance" is:

"Test results indicated that the AcuPulse W with the 90° Side-firing Handpiece equipped with the new configuration of disposable tips performs in accordance with its requirements and specifications similarly to its predicate device."

This statement confirms that the new disposable tips meet functional and safety requirements comparable to the existing multiuse tips, ensuring substantial equivalence to the predicate device. However, it does not provide specific quantitative acceptance criteria or detailed study results generally associated with AI/ML device performance.
