USER-FRIENDLY INTERFACE TMA has a graphic user interface with just
two treatment parameters. It is simple to use, with a quick
learning curve so that treatment can be easily and safely
delegated.
MEDICAL-GRADE TITANIUM TIP A medical-grade titanium tip is located
in the handpiece and is reusable and easy to clean. This in situ
pre-heated tip is also sterile upon operation. As the tip moves
forward and makes very brief contact with the skin, thermal energy
is transferred. There is no emitted radiation, smoke, fumes or
bleeding. Furthermore, goggles are not required as the system is
eye safe.
TWO LIGHT HANDPIECES Customize patient treatment precisely: TMA’s 2
handpieces – facial and periorbital – can be used for large (1 cm2)
and small (0.3 cm2) treatment areas. The periorbital handpiece is
ideal for around the eyes, on narrow treatment areas around the
nose, on deep wrinkles on upper lips, and stretch marks.
ABOUT TMA THERMO-MECHANICAL ACTION TECHNOLOGY
TMA is a technology, that’s forward in thinking and in its action.
It uniquely combines motion and heat with the forward movement of a
medical-grade titanium tip. This proprietary non-laser fractional
technology transfers thermal energy to skin very quickly and
safely: energy is emitted through a matrix of tiny pyramid-shaped
pins made of biocompatible materials covering a treatment area of
1cm². The pins are heated to a temperature of 400°C and are
self-sterilized.
The tip consists of 81 tiny pyramids (9 x 9) which are heated to a
temperature of 400°C . As the tip moves, it makes brief contact
with the skin at the apex of the pyramids without protruding the
skin. This creates a matrix of discrete nonablative hemispherical
coagulation zones (depth of up to 250μ, width of up to 500μ).
THE THERMAL EFFECT
During treatment, the pins are introduced to the surface of the
skin at a precisely-controlled speed and create brief contact with
the skin lasting only a few milliseconds. This enables the thermal
energy stored in the pins to be transferred to the skin. The
thermal transfer results in an array of tiny non-ablative
coagulation sites. Because the tiny tip pyramids hold a limited
amount of energy, burns and tissue charring are prevented.
WHY IS THE PAIN RELATIVELY LOW?
The reason why pain is relatively low during treatment with TMA
compared to the ablative CO2laser is primarily due to the transfer
of a relatively lower amount of energy to the skin by TMA. This is
made possible by utilization of a more efficient energy transfer
method (conduction vs. radiation) and the longer pulse duration
(e.g. 10ms vs. 1ms) of TMA as compared to the CO2 laser. The pain
nociceptors in skin are located in the epidermis and dermis. These
pain receptors are sensitive to the rate at which the temperature
changes over time. For example, a CO2 laser generates heat quickly:
CO2laser heating to 400°C takes about 200ns whereas the TMA heating
effect is slower by at least 1 magnitude of order resulting in
milder pain.
ENHANCED SKIN PERMEABILITY
Research shows that TMA creates superficial channels in the stratum
corneum, allowing enhanced permeability to topically applied
hydrophilic substances, that are applied after treatment. TMA’s
intended use does not currently include tissue permeability
