Pulsar® Monopressure Membrane Valve

Founded in 1976, SOPHYSA was the pioneer in the development of adjustable neurosurgical valves to treat hydrocephalus. Introduced in 1984, the Sophy® valve was the first adjustable valve in the World allowing non-invasive adjustment of operating pressures, to match an individual patient's changing clinical needs. Acquired in 1989 by the Japanese tkb Group, SOPHYSA expanded quickly in France, and abroad, gaining global recognition in the field of Neurosurgery. In 2004, SOPHYSA launched the Polaris® valve, the first adjustable valve with a lock, specifically designed to resist unintentional changes in operating pressure – a milestone in adjustable valve safety. Polaris® offers the patient an unequalled security against the clinical risks associated with those dysadjustments. In 2005, SOPHYSA introduced Pressio®,a user-friendly Intra-Cranial Pressure monitoring system for neurosurgery and neurotrauma, bringing the continuous intracranial pressure monitoring to a new level of performance and ease of use. As a neurosurgery specialist, SOPHYSA manufactures and markets a wide range of neurosurgical implants for the treatment of hydrocephalus, including various types of valves, catheters, reservoirs and accessories, a range of ICP sensors and external drainage systems, as well as subcutaneous spinal access ports. Our research and Development activities and production are based in Besançon, the French capital for micro-mechanics, in a state-of-the-art manufacturing facility, inaugurated in 2007. SOPHYSA also has branch offices in Belgium, in Braine l'Alleud, and in the U.S., in Crown Point, Indiana.
