Dear Doctor, Please find the attached video of Codman Hakim Programmable Valve Product Detailing Video. The Codman Hakim Programmable Valve offers the ability to optimize the opening pressure of a shunt system before and after implantation. a shunted patient’s condition will often change over the course of their treatment making pressure changes necessary. The programmable valve allows a surgeon to non-invasively change the opening pressure between 30 mm H2o and 200 mm H2o in 18 steps; negating the need for revision surgery to alter the valve pressure. Thanks,
