Enhanced Patient Care Active people spend about 2/3 of the day walking, standing or sitting upright. Consequently, hydrocephalus patients with a shunt often risk overdrainage. The new proSA is the result of continuous evolution of the proven and accepted gravitational technology. The proSA allows individual adjustment, which can be necessitated by body growth or increased peritoneal pressure. The introduction of the gravitational technology for hydrocephalus treatment brought new options to avoid the symptoms and long-term complications caused by overdrainage. “ The analysis of our material...

Gravity approved The Miethke valves proGAV, GAV and paediGAV based on this technology offer effective solutions for pediatric and adult hydrocephalus [1,2,3,4,5]. MRI approved Like the proGAV, the proSA features an “Active Lock” mechanism. This mechanism protects the valve against inadvertent adjustment by external magnetic fields and is MR-conditional* up to 3 Tesla [6,7,8,9]. Approved instruments The patented adjustment and verification instruments allow easy, fast and uncomplicated treatment at any location, without having to expose the patient to X-ray [1,9]. * According to the new ASTM...

Enhanced Treatment Options proSA offers extended options and possibilities for all fields of hydrocephalus treatment, beyond the limitations of conventional adjustable shunt systems. The pressure setting range of 0 to 40 cmH2O allows individual adjustment for each patient. The proSA valve can be combined with any differential pressure valve. One valve fits all patients Wide range of pressure levels for adjustment between 0 to 40 cmH2O Automatic adaption of pressure depending on bodyposition within adjusted pressure range Titanium shell ensures reliable function, independent of external and...

Initial Valve Adjustment [cmH2O] The proSA valve should be implanted in combination with a differential pressure unit. The less mobile the patient, the lower the opening pressure to be set. Individual characteristics of the patient, e.g. the Body Mass Index, adiposity, pregnancy, growth of pediatric patients, etc. can be easily adapted for, by adjusting the gravitational unit in the course of the therapy. * These guide values are not binding. Other settings may be preferable depending on the individual patient and anamnesis proSA in X-ray view unused range

The Function – Supine Function The proSA is an adjustable gravitational valve whose opening pressure automatically adapts to the patient’s body position. In the supine position, the opening pressure of the proSA is 0 cmH2O. In this mode, the shunt opening pressure is completely defined by the differential pressure unit. Optional differential pressure unit Adjustable gravitational unit Valve opening pressure* (cmH2O) * The graph only represents the opening pressure of the proSA. For the opening pressure of the shunt system as a whole, the opening pressure of the differential pressure unit...

The Function – Upright Function When the patient is in an upright body position, the gravitational unit and the differential pressure unit work together, i.e. the opening pressure of the shunt system as a whole is the sum of the differential pressure level and the pressure level set at the gravitational unit. Optional differential pressure unit Adjustable gravitational unit Adjustment range proSA body position

Adjustment Select the appropriate opening pressure on the adjustment instrument. Position the instrument according to instruction for use on the valve. Unlock the mechanical coupling “Active-Lock” by applying mild pressure on the trigger button and set the intended opening pressure of the adjustable valve. Any adjustment can easily be confirmed using the verification instrument.
