Asclepion QuadroStarPRO

QuadroStarPRO is a compact vascular laser from Asclepion Laser Technologies in Jena, Germany. The FDA cleared it under K133297 in June 2014 in two versions. QuadroStarPRO YELLOW emits 577 nm and is cleared for benign vascular and pigmented lesions. QuadroStarPRO GREEN emits 532 nm and is cleared for vaporization and photocoagulation of benign vascular and pigmented lesions in soft tissue. The filing calls it a class IV solid state diode laser, with up to 8 W delivered through a transfer fiber and handpiece, an optional scanner, and pulses from milliseconds up to continuous emission.

The predicates explain its background. One was Asclepion's YellowStar, a copper bromide laser emitting 511 and 578 nm, and the other was the QuadroStar 532. The filing notes that newer multi-color diodes made 577 nm practical without copper vapor or copper bromide sources. Asclepion now offers only the YELLOW. Its brochure describes the source as a high-power optically pumped semiconductor laser at 577 nm, rated at 5 W maximum, with pulse durations from 1 ms to 95 seconds or continuous wave.

The current YELLOW runs at 0.5 to 100 Hz and offers Basic, Expert, Scan, Burst, Varix and CW modes, with Scan switching on automatically when the scanner is connected. The standard handpiece has a 1 mm spot, with 0.5, 1.5 and 2.8 mm optics as options. The optional scanner uses a 1 mm spot over an area up to 15 by 15 mm, has integrated skin cooling and adjusts scan density from 60 to 100 percent. The unit weighs under 15 kg, measures 42 by 38 by 19 cm and has a 5.7 inch display. A wheeled transport case is available.

The wavelength on the label tells GREEN from YELLOW, so photograph it. List each handpiece optic and whether the scanner and transport case are included. A buyer will check the transfer fiber for damage, the handpiece lens, and that the scanner's cooling works.
