Neurodiagnostic and neuromonitoring solutions since 1979

John Cadwell, BSEE, MD, saw a need for innovative and reliable neurophysiology instruments during his residency at the University of Washington School of Medicine in Seattle, Washington, USA. John used his experience in electrical engineering and medicine to design the world’s first microprocessor-controlled EMG instrument. John partnered with his brother, Carl Cadwell, DDS, and together they formed Cadwell in 1979. Throughout the years, Cadwell has grown its neurodiagnostic offerings into EEG, IONM and PSG.

Today, Cadwell employs more than 110 people at headquarters in research, hardware design, software design, assembly, marketing, distribution, sales support, and customer support. A network of sales and support representatives serve the U.S.A., and international managers in China, Singapore, the Netherlands, and Dubai serve our international distributors.

43 Years in Business (as of 2022)

Atys Medical are committed to combine sustainable growth with innovation and creativity to provide high-quality solutions, expertly made in France, and used all over the world.

They have been specialising in the design, manufacture and sales of transcranial Doppler devices and vascular physiologic diagnostic systems for 30 years. 

The state-of-the-art equipment are dedicated to angiology, phlebology, diabetic patient monitoring, neurology, anesthesia,  resuscitation and intensive care.

Atys offers solutions for clinical use as well as for research. They have more than 30 years of experience and unique competence in ultrasound, Doppler, infrared photoplethysmography as well as arterial pressure measurement making Atys medical a leader in assessing peripheral and intracranial blood flow.

During the last 30 years they have kept setting significant milestones.

In 1985, with the introduction of the world’s first device that can simultaneously monitor blood flow velocity in the middle cerebral artery and cardiac output.

In 2004, they marketed  the first portable high resolution ultrasound scanner for skin imaging (melanoma assessment), the DERMCUP.

In 2009, Atys launched the SYSTOE on the market. SYSTOE is the first automated and affordable device that measures reliably toe systolic pressure. SYSTOE allows improving the early diagnosis of peripheral arterial disease especially among patients at higher risks as elderly patients and diabetics.

In 2012, thanks to a fruitful cooperation with Dr Rune Aaslid, Atys were able to market the first transcranial Doppler Holter. This portable, light and autonomous device, TCD-X, can record transcranial Doppler signal on patients “in action”. The innovation was double as the TCD-X was also fitted with one of the first two robotic transcranial probes available on the market.

From 2016, all of Atys’ desktop transcranial Doppler devices can be fitted with one or two robotic probes.

Their main target is to made medical examinations easier and more affordable.

Atys Medical is based out its Global Headquarters in Soucieu en Jarrest, France.
