The UltraLase Flexible CO2Laser Waveguide is indicated for use with CO2 laser systems for general and plastic surgery procedures, neurosurgery, and ophthaimology, oral surgery, oto-rhino-laryngology, podiatry, gynecology and urology procedures. It is used to deliver laser energy for incision, excision, ablation, vaporization, and coagulation of soft tissues.

The UltraLase Flexible CO2Laser Waveguide can be used in open surgical procedures and endoscopic procedures.

The indications for use for which the delivery system is used are dependent upon the cleared indications for use of the laser system and laser system accessories to which it is attached.

The UltraLase Flexible CO2 Laser Waveguide is a laser delivery system for use in surgical procedures where a flexible delivery system would allow easier and more efficient delivery of laser energy to the targeted tissue. The waveguide consists of a flexible silica capillary whose inside wall has been coated with a durable coating that is highly reflective at the intended wavelength of use. A fiber optic connector is attached to the proximal end of the waveguide and the waveguide is covered with a plastic sleeve for protection. The UltraLase Flexible CO2 Laser Waveguide is supplied with a single use handpiece attached or without a handpiece so it can be used with various reusable handpieces such as the TTI Medical ACCU-Beam Fiberoptic Handpieces.

The UltraLase Flexible CO2 Laser Waveguide is designed to operate at 10.6µm and has a broad enough transmission band to accommodate any laser operating in this region.

The laser energy is coupled into the waveguide using the supplied focusing lens and travels down the waveguide by multiple bounces off the inner reflective surface, exiting to the tissue at the distal end.

The UltraLase Flexible CO2 Laser Waveguides come with either a 905 SMA connector or a 953 ST connector and are therefore can be used with any CO2 Laser that is compatible with one of these connectors. The waveguide is supplied in several diameters and lengths as shown in the following chart.

It is recommended that a purge gas system using an inert gas such as helium be used to force an inert gas through the waveguide for cooling and to keep the inner channel of the waveguide free of debris.

The waveguides delivery systems are supplied sterile for single use.

Here's an analysis of the provided text regarding the UltraLase Flexible CO2 Laser Waveguide's acceptance criteria and studies:

1. Table of Acceptance Criteria and Reported Device Performance

Important Note: The provided document is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices. It largely describes the device's technical specifications and intended uses, and then states that it was "bench tested" for transmission bandwidth and percent transmission. It does not present specific numerical acceptance criteria or detailed results from these bench tests beyond confirming they were performed. The "reported device performance" in the table above is thus an inference that the device met internal criteria for its design specifications, rather than a direct report of specific performance values against pre-defined numerical objective criteria.

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

The document does not explicitly state a sample size for a dedicated "test set" in the context of clinical trials or specific performance verification. The performance testing mentioned ("bench tested to establish transmission bandwidth, and percent transmission") refers to laboratory/engineering testing rather than a clinical study with a distinct patient test set.

• Test Set Sample Size: Not specified for clinical or comparative studies. For bench testing, the sample size of waveguides tested is not mentioned.
• Data Provenance: The bench testing is implied to be internal to Laser Engineering (the applicant). There is no mention of country of origin for any data or whether it was retrospective or prospective. Given the nature of a 510(k) submission for this type of device, extensive clinical data from human subjects is often not required if substantial equivalence can be demonstrated through technological characteristics and engineering testing.

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

This information is not applicable or not provided in the document. The submission is a 510(k) for a CO2 laser waveguide, which is a device for energy delivery. The performance testing described is engineering-focused (transmission bandwidth, percent transmission). There is no mention of a "test set" that would require expert-established ground truth in a diagnostic or interpretive context.

4. Adjudication Method for the Test Set

This information is not applicable or not provided. As there's no mention of a clinical "test set" requiring expert interpretation or diagnosis, no adjudication method would be in play.

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

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done or reported in this document. The submission focuses on demonstrating substantial equivalence through technological characteristics and bench testing, not on comparative effectiveness with human readers.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was Done

This question is not applicable. The UltraLase Flexible CO2 Laser Waveguide is a physical medical device (a fiber optic waveguide) used to deliver laser energy, not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.

7. The Type of Ground Truth Used

For the described "bench testing to establish transmission bandwidth, and percent transmission," the "ground truth" would be established by physical measurements and engineering standards/specifications for laser light transmission through a fiber optic waveguide. It is not expert consensus, pathology, or outcomes data, as those are relevant for diagnostic or treatment efficacy studies.

8. The Sample Size for the Training Set

This information is not applicable or not provided. As the device is not an AI/ML algorithm or a diagnostic tool that learns from data, there is no "training set."

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

This information is not applicable or not provided. As there is no "training set," there is no ground truth establishment for one.
