The HOLLYWOOD SPECTRA Laser System contains a Nd: YAG (Neodymium-doped Yttrium Aluminum Garnet) resonator which generates Q-switched and/or pulsed laser sources at the nominal wavelength of 1064 nm and 532 nm using KTP. The outputs of each laser generator and the aiming beam (655 nm) are delivered by articulated arm to a fixed (collimated), or focusing variable (zoom) spot handpiece, or a dual focused dots microbeam handpiece, or a 585nm/650nm dye laser converter handpiece. The dye handpieces convert the KTP 532 nm wavelength beam into a 585 nm or 650 nm wavelengths, correspondingly.
When the beam contacts human tissue, the energy in the beam is absorbed, resulting in a very rapid, highly localized temperature increase to the target chromophores such as melanin and tattoo particles. This increases localized temperature of the chromophores. The instantaneous temperature-increase causes fragmentation of the chromophores to smaller particles. By directing the beam onto specific tissue locations, using different handpieces, and controlling the treatment fluence, the intensity of the temperature of the target can be varied. The physician can optimize the effect for different applications by controlling the energy of the laser pulse and the spot size of the treatment beam.
The user activates laser emission by means of a footswitch. All handpieces are equipped with sensors for automatic detection of a handpiece type and the spot size. The HOLLYWOOD SPECTRA laser system is controlled via a touchscreen guided user interface in the front of the device.
The provided text is a 510(k) summary for the HOLLYWOOD SPECTRA Laser System. This document focuses on demonstrating substantial equivalence to predicate devices based on technical characteristics and indications for use, rather than presenting performance data from clinical studies directly.
Therefore, the document does not contain the information requested in your prompt regarding acceptance criteria and performance data from a study that proves the device meets those criteria.
Specifically:
- 1. A table of acceptance criteria and the reported device performance: This information is not present. The tables provided (Table 1 and Table 2) are "Technical Characteristics Comparison" tables, comparing the proposed device's specifications to those of predicate devices. These are not acceptance criteria tables from a performance study.
- 2. Sample sized used for the test set and the data provenance: Not applicable, as no performance study with a test set is described.
- 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
- 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
- 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: Not applicable. This device is a laser system, not an AI-assisted diagnostic tool for human readers.
- 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
- 7. The type of ground truth used: Not applicable.
- 8. The sample size for the training set: Not applicable.
- 9. How the ground truth for the training set was established: Not applicable.
The "PERFORMANCE DATA" section (Page 13) of the summary lists various types of engineering and safety testing performed (Biocompatibility, Sterilization and Shelf-Life, Electrical Safety and EMC, Software Verification and Validation, Performance Bench Testing). However, these are bench tests and safety compliance tests, not clinical performance studies with acceptance criteria for specific medical outcomes or diagnostic accuracy. The purpose of these tests is to show that the device is safe and functions according to its design specifications, and is substantially equivalent to existing devices, not to demonstrate clinical efficacy against pre-defined acceptance criteria in a patient population.
