Codman Neuro has developed a new MRI-resistant programmable valve for the treatment of hydrocephalus with eight different pressure settings, including a "virtual off" setting.
The new Codman Certas Plus programmable valve enables neurosurgeons to preoperatively choose from eight low- to high-pressure settings to control the rate of drainage of cerebrospinal fluid (CSF) from the brain. The valve pressure can be read and adjusted noninvasively or even turned "virtually off" (valve pressure consistently above 400 mm H2O) anytime after implantation using the Codman Certas toolkit, which uses magnetic force to change settings.
The Codman Certas Plus valve is resistant to unintended changes in the valve setting in a 3-tesla MRI scanner and may be integrated with Codman Neuro's Bactiseal antimicrobial catheter and/or Siphonguard antisiphon device, depending on the surgeon's preference.
