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

Where it all started

Sophysa started operations in 1976 in France, and set a significant milestone in 1985 with the introduction of the world’s first programmable valve Sophy®. This represented a major advance in the treatment of hydrocephalus. The development of the Sophy® valve has contributed to the improvement of surgical management by allowing neurosurgeons to modify the operating pressure of the valve through the skin, and adapt it to the precise clinical needs of each patient. This reduces the number of surgical reoperations and allows patients a greater chance of full recovery without the need for invasive, secondary surgery.

In 1989, Sophysa joined TOKIBO group. The company quickly expanded in France, and gained global recognition for its innovative products and expertise in the field of neurosurgery. To consolidate its lead, Sophysa perfected the concept of the adjustable valve in 2004 with the Polaris®. This was the first MRI-Stable valve (magnetic resonance imaging (MRI) systems up to 3T and daily life magnetic fields), thanks to a security lock designed to avoid dysadjustments. The company innovated again in 2005 with Pressio®, an intracranial pressure monitoring system based on micro-sensors used in neurosurgical intensive care units and in neurotraumatology. In 2007, the next generation Pressio® Catheters was launched, offering a unique solution for the joint continuous measurements of intracranial pressure and temperature.
