Abstract
On April 2010, Vbeam®, flashlamp pumped long-pulsed dye laser system (Candela Co., Wayland, MA, USA), was approved for the use of the treatment of cutaneous vascular lesions (capillary malformations, infantile hemangiomas and telangiectasias) in Japan. This system can emit the 595 nm laser beam, and the pulse duration is adjustable from 0.45 msec to 40 msec changing the sub-pulse sequences. And cryogen spray cooling system is equipped on the output-handpiece, and cryogen spurts before laser irradiation can protect the epidermal heat damage. The longer wavelength allows the deeper penetration into the skin and the longer pulse duration with high fluence is considered to be optimal for damaging lager diameter microvessels with less adverse effects.
We report the characteristics of this new approved laser device from the point of mechanical specifications in this article.
