Device Description

The New Star Model 2500 is a compact, portable, self-contained system that produces a bearn of infrared radiation at 2,100 nm wavelength for treatment, and a visible laser diode beam at 532 nm for aiming. The system emits a pulsed laser beam which is delivered to the treatment site using a fiber-optic delivery system. The system consists of a laser console, a fiber-optic delivery system, and a footswitch. The system provides safety features that are designed to protect the user and patient from high voltages and laser emissions. The console consists of a control panel, a laser head assembly, a power supply, and a cooling system. It also contains an ON/OFF key switch, Emergency Off switch, External Power Meter connector, Fiber-Optic receptacle, Interlock Jumper plug/receptacle, and a footswitch receptacle. The fiber-optic delivery system includes a linear flash lamp pumped holmium laser cavity and resonator, a 3 milliwatt laser diode, two optical detector assemblies, lenses and cables. The footswitch is used to initiate delivery of laser energy according to preset parameters.

Study That Proves the Device Meets Acceptance Criteria:

The device's compliance is established through non-clinical testing and comparison to a predicate device to demonstrate substantial equivalence.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
No human test set or data provenance (country of origin, retrospective/prospective) is mentioned in the provided text. The evaluation is based on non-clinical engineering and performance tests against established standards and comparison to a predicate device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
Not applicable. The submission does not detail the use of human experts to establish ground truth for a test set, as the evaluation is based on technical specifications and substantial equivalence to a predicate device, not on diagnostic or interpretive performance.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. There is no mention of a human test set requiring adjudication in this submission.

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 submission is for a laser surgical instrument, not an AI-assisted diagnostic or interpretive device. Therefore, no MRMC study or AI assistance evaluation is relevant.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is not an AI algorithm; it's a physical medical device. The "standalone" performance refers to the device's operational characteristics as detailed in the non-clinical tests.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for the device's performance is based on established engineering specifications, national and international standards for such devices (e.g., IEC 60601-1-2; EN 61000-3-3), and the known performance characteristics of the legally marketed predicate device (Allmed Systems, Inc. Sphinx30). This is primarily a technical and comparative ground truth rather than a clinical one derived from patient outcomes or expert consensus on clinical data.

8. The sample size for the training set:
Not applicable. This is a medical device, not a machine learning algorithm, so there is no "training set."

9. How the ground truth for the training set was established:
Not applicable. As there is no training set for a machine learning algorithm, there is no ground truth established for one.

IV. Device Description

{1}------------------------------------------------

The system provides safety features that are designed to protect the user and patient from high voltages and laser emissions.

The console consists of a control panel, a laser head assembly, a power supply, and a cooling system. It also contains an ON/OFF key switch, Emergency Off switch, External Power Meter connector, Fiber-Optic receptacle, Interlock Jumper plug/receptacle, and a footswitch receptacle. The fiber-optic delivery system includes a linear flash lamp pumped holmium laser cavity and resonator, a 3 milliwatt laser diode, two optical detector assemblies, lenses and cables. The footswitch is used to initiate delivery of laser energy according to preset parameters.

Summary of Non Clinical Tests V.

New Star utilized IEC 60601-1-2; EN 61000-3-3 test standards to establish a basis for the determination of equivalence. The NS2500 Holmium Laser System performance characteristics were established by referencing the known performance characteristics of the predicate device. Specifications for the NS500 Laser System were established to assure that the predicate system and the NS2500 Laser System performed in an equivalent manner. Performance specifications were set utilizing national and international standards for such devices with respect to output, indications for use, safety features and electromagnetic interference where it was established as suitable for the environment of use. All testing was conducted and established that the NS2500 Holmium Laser System met or exceeded its design specifications and performed equally or better than the stated performance of the predicate.

Conclusions drawn from these non-clinical tests demonstrate that the device is as safe, as effective and performs at least as safely and as effectively as the legally marketed device identified in this Summary.
