Flow Regulated Valves OSV II™
Limits uncertainty by automatically adjusting to the patient’s changing need.
OSV II™ valves simplify:
Your shunt choice:
- Only 2 drainage rates for the whole population.
- No further setting adjustment needed as it automatically adjusts to the patient’s needs to maintain a physiological flow rate.
- No need to add accessories such as anti-siphon devices.
- No need to find the right programmer in emergency cases.
Your patient management:
- Better overall shunt survival rate 62% at 5 years 1 compared to 53.1% for programmable shunts.2
- Limit overdrainages as flow regulated shunts manage both postural & vasogenic events.1,3,6
- Reduce slitlike ventricles 10.8% for DP, 10.5% for Delta & 3.6% for Flow Regulated.5
- No significant image distortion in MRI thanks to constitutive materials.4

Indications
The OSV II Valve System is an implantable system used in the treatment of patients with hydrocephalus, to shunt CSF from the ventricles to the peritoneal cavity or other appropriate drainage site such as the heart’s right atrium.
The OSV II Lumbar Valve System is an implantable system used in the treatment of patients with communicating hydrocephalus to shunt CSF from the lumbar subarachnoid region to the peritoneal cavity.
Contraindications
This valve system should not be implanted when an infection along the shunt pathway (e.g. meningitis, ventriculitis, peritonitis) is suspected. It is advisable to postpone valve implantation if an infection is present anywhere in the body (septicemia, bacteremia). Atrial shunting is not advised for patients with congenital heart disease or other serious cardiopulmonary abnormalities.
The OSV II Valve System should not be used for drainage of extraventricular fluid collections such as hygromas or cysts; such conditions are typically treated with very low differential pressure valves.
The OSV II Valve System and Lumbar Valve System should not be implanted in patients with untreated choroid plexus tumors. Such tumors produce CSF at rates in excess of the specification of the flow regulation Stage II, and the OSV II Valve System and Lumbar Valve System would underdrain under these conditions. The OSV II Lumbar Valve System should not be used in patients with non-communicating hydrocephalus.
