Device Story

Spectrum Veinlase is a surgical laser system utilizing flashlamp-pumped Nd:YAG technology; delivers 532nm (frequency-doubled) and 1064nm wavelengths. Operates in continuous or 'Captured Pulse' modes for high-energy, short-duration delivery. Used by physicians in clinical/surgical settings for photocoagulation, vaporization, and cutting of soft tissues. System includes cooling, interlocks, and display controls. Output is laser energy delivered via fiber-optic delivery devices to target tissue; enables precise tissue management, hemostasis, and lesion removal. Clinical benefit derived from controlled thermal tissue interaction.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

# Description of Submitted Device:

The Combination Nd:YAG and Solid State, (Frequency Doubled Nd:YAG) Surgical Laser System is an instrument used in the application of photocoagulation of soft tissue using a 532nm wavelength. The system has the ability to use a 1064nm wavelength for applications including; Coagulation, Vaporization, and Cutting. The system can run both wavelengths in "Captured Pulse" which delivers high energy at very short pulse durations. The laser light is "pumped" by flashlamp technology.

### Technological Characteristics and Substantial Equivalence:

The Coherent, VersaPulse uses O-switched frequency doubled, Q-switched Nd:YAG, and Q-switched Alexandrite: YAG laser energy to deliver 532nm, 1064nm and 755nm wavelengths. The VersaPulse delivers the same wavelength, similar average power, pulses of equivalent duration, and treatment spots of equivalent diameter. The indications for use are also similar.

TheThermolase Softlight Laser uses the identical wavelength. A Nd: YAG Rod, the output of which is 1064nm. The Softlight laser uses a carbon-based cream to aid in the removal of unwanted body hair and for skin resurfacing.Similar average power, pulses of equivalent duration, and treatment spots of equivalent diameter.

The Laserscope Orion Series Laser System offers the same 532/1064 capability and is capable of the pulsed power technology that we are offering.It is indicated in the treatment of dark ink tatoos. The laser delivers similar strength, similar average power, pulses of equivalent duration, and treatment spots of equivalent diameter. The "Starpulse" allows it to deliver high energy at short pulse durations.

The Cynosure PhotoGenica LPIR Laser uses a 755nm wavelength, obtained from a Flashlamp-Excited Solid State Pulsed Laser is indicated in the treatment of leg veins that are between 0.6 mm to 3.0 mm in size. The LPIR uses a HENE (CW) 543nm green aiming beam. Other areas of the PhotoGenica LPIR including; pulse duration, and treatment spots are equally similar.
