The OSV II® Smart ValveT System is the intelligent choice for meeting the complex demands of hydrocephalus shunting.
Introduced in 1987, the Orbis-Sigma® valve was the first valve to manage hydrocephalus through flow-regulation rather than conventional differential-pressure regulation. The valve operates a unique, 3-stage, variable resistance mechanism that regulates flow through the valve (stage III) at a rate close to that of CSF secretion, therefore minimizing the risks of under or overdrainage. The same clinically-proven design is the mechanism used in the new OSV II valve, with the addit
