The France-based company Sophysa announced it will begin to use Eviva polysulfone resin from Solvay Specialty Polymers in its implantable brain shunt valves and access ports. The announcement was made at the EuroSpine Annual Meeting in Lyon, France.
According to a company press release, Sophysa offers implantable brain shunts for the treatment of hydrocephalus that feature adjustable and mono-pressure valves made of Eviva polysulfone (PSU). The valves are designed to control the drainage of the cerebrospinal fluid from the brain ventricles. The company also offers Soph-A-Port range of implantable access ports for chemotherapy and morphine therapy. The ports are also made with Eviva PSU and can be used for arterial, venous, peritoneal and spinal accesses. Both products have received the CE Mark.
According to company officials, the material maintains its dimensional tolerance out of the mold and requires no machining.
