Ellipse MultiFlex Nd:YAG handpiece

Ellipse Nd:YAG laser technology  

Purpose-built for vascular treatments such as leg veins and onychomycosis

The Nd:YAG laser module employed in the MultiFlex+ system features a number of innovations that make it ideal for treatment of leg veins and a range of other vascular lesions as well as onychomycosis.
Because Ellipse MultiFlex+ employs a new, patented focused air cooling system for pre, parallel and post cooling patients experience less discomfort with the Ellipse Nd:YAG than with many alternative cooling systems. While some systems rely on expensive cryogen spray or additional operators for external coolers Ellipse MultiFlex+ produces its own stream of cooled air fully integrated in the hand-piece at no additional costs.

The Nd:YAG hand-piece furthermore offers superb ergonomics with smooth adjustability of working light, aiming beam and spot size.

Ellipse's Nd:YAG laser comes with 3 interchangeable tips: A standard circular tip for treatment of most vessels. A semi-circular tip for use close to the nose or eye. And a Sapphire window tip to treat underlying feeder vessels.

What does Nd:YAG mean?

Nd:YAG (neodymium-doped yttrium aluminium garnet; Nd:Y3Al5 O12) is a crystal that is used as a lasing medium for solid-state lasers.

How does an Nd:YAG laser work?

A laser is an electronic-optical device that emits coherent, monochromatic light. The Ellipse Nd:YAG laser, with a wavelength of 1064 nm, is optically pumped using a flash lamp.
This permits the Ellipse Nd:YAG to draw on our established knowledge of controlling the pulse shape.

For treatment of vascular lesions long 35 ms long pulses are used whereas treatment of onychomycosis is based on the use of short 0.3 ms pulses.

How does an Nd:YAG laser work on vascular lesions?

To clear leg veins and other vascular lesions, the vessels must be constricted. A 1064 nm wavelength Nd:YAG laser sends energy into the blood and vessel walls, where it is absorbed by blood. Red blood cells are heated, causing met-haemoglobin formation and greater absorption. This causes microclotting and heating of the vessel wall, leading to complete or partial collapse. The constricted vessel then degenerates, and the visible leg veins disappear from the surface of the skin.

Treating vascular conditions in general is based on the principle of selective photothermolysis performed with a single long pulse.
A condition of good results is that the Pulse Time is chosen noting the thermal relaxation time for the actual vessel thickness.
The ideal immediate response to treatment with vascular laser is coagulation of the vessel with no other apparent effect. This effect can be observed in the form of bluish or greyish discolouration visible on the skin surface. In leg veins, blanching or disappearance of the vessel may occur.

Why is the Nd:YAG laser better than I²PL for treatment of certain vascular lesions such as leg veins?

Leg veins and reticular vessels are normally deep, which is why Nd:YAG in most cases respond better than IPL.
I²PL is good for treatment of very superficial small vessels or blanching after sclerotherapy. Note that lasers or light can only be used 1 month post sclerotherapy.

How does an Nd:YAG laser work on onychomycosis (nail fungus)?

The exact mechanism of onychomycosis (nail fungus) treatment is not totally known. Heating the fungus is one major factor, but introducing a sub-millisecond pulse adds a “photo-acoustic” effect to the treatment, weakening the cell structure of the fungus.

A series of flashes of infrared light is aimed across the whole nail, including the nail folds (the skin immediately surrounding the sides and base of the nail). This heats up and destroys the fungus that is present. To ensure complete coverage, the whole series of pulses is repeated four times, and the individual flashes overlap each other.
