LET Health LLC is an official representative of Research Laboratory of Medical Electronics “LET Medical” (Russia) in North America.

We are a young company with a mandate to bring you the latest R&D in electronic energy healing in order to end your pain for good.

LET Medical Research Laboratory in Taganrog, Russia, led by Dr. Alexander Karasev, the original SCENAR, COSMODIC, and ENS inventor, pioneered and over almost three decades supported the cutting-edge research in the area of adaptive electrical stimulation as the most effective, universal, natural, and drug-free method of pain management.

By forming LET Medical in 1990, Dr. Karasev continued independently his work that started within the Soviet Space Program and resulted in the development of SCENAR – a hand-held portable device designated for cosmonauts to keep them healthy while in space. Later the SCENAR was dubbed a “Star Trek healing device” by the Western press, and in the last 30+ years, there were many situations where it turned out to be not such an overstatement after all.

SCENAR became possible because Dr. Alexander’s “outside the box” thinking merged medicine and physics (Alexander Karasev is both an MD and an electronic engineer), Eastern and Western health paradigms (conventional and holistic medicine), and even science and religion. SCENAR was designed as a simplified, but still, a feedback-based analog of a living system – self-controlling and self-regulating electronic “mirror” constantly adapting to the body and its needs and gently guiding and supporting it in its healing efforts.

LET Medical and Dr. Karasev spearheaded the SCENAR evolution into the 21st century, and in the wake of it the COSMODIC technology was born as “the second generation SCENAR”. COSMODIC came as a natural progression of SCENAR on the next quality level: subtler, more profound, more regenerative electrotherapy that used micro-resonances in order to tune into, amplify, and harmonize the body’s healing reactions.

Since 1990 LET Medical has developed and produced 7 series of SCENAR and COSMODIC devices, with 5-9 models in each series. Now people in more than 30 countries all over the world use these devices as their Personal Health Assistants.

LET Medical SCENARs became an origin of other SCENAR-type devices (adaptive electrical stimulators) developed and manufactured worldwide. COSMODIC devices, however, remain the exclusive product of LET Medical. There are no other COSMODIC manufacturers anywhere, and there are no known COSMODIC copycats. The technology is too sophisticated to be reverse engineered without an original know-how.

Currently, LET Medical is working on the next (the third) SCENAR generation – ENS. ENS devices have been already released to the world with very encouraging results, but the ENS technology still remains quite an enigma. LET Medical is not rushing to reveal its secrets, and it may take a while until we understand how it is possible for ENS to enhance and optimize the flow of bioenergy, reach the core body programming, trigger regeneration, and give everyone using it the Zen “inner smile”, among other things.

LET Medical is the owner of many patents, trademarks, and service marks in Russia and abroad, including “COSMODIC®”, “КОСМОДИК®”, “SCENAR®”, “СКЭНАР®”, “ENS®”, “ЭНС®”.
