Polaris® Valve Adjustment

The Polaris® Adjustment Kit :

  • allows easy, precise and fast procedure
  • permits a painless adjustment
  • offers a direct pressure reading with the Compass
  • is provided in a shielded case
  • includes a Polaris® demo valve



1 - Operating pressure range visible on Locator MUST match valve range.


2 - Valve location should determine optimum patient position for adjustment.
Having valve horizontal is recommended.


3 - Position Locator parallel to valve, with valve seated in center cut-out, and green arrow pointing in direction of CSF flow path, aligning Locator with valve axis.


4 - Place Compass within Locator.


5 - Adjust Locator orientation, in same horizontal plane as valve, so that Compass needle centers within white target circle, and aligns with current operating pressure setting. Note the valve's current operating pressure setting.


6 - Without moving Locator, remove Compass, then insert Magnet, with center line of Magnet aligned with current operating pressure setting.


7 - Without moving Locator, quickly slide Magnet, with back and forth motion, along the current operating pressure setting axis. With Magnet again centered inside Locator, turn magnet slowly, just beyond the highest or lowest operating pressure setting, whichever is furthest from the initial operating pressure setting.

Without moving Locator, remove Magnet vertically, and place Magnet 0.5 meters away from valve, then insert Compass into Locator. If Locator orientation is accurate, Compass needle aligns exactly with the highest or lowest operating pressure setting, providing a reference point for calibration of the Locator along the valve's axis. If the Compass needle does not align exactly with the highest or lowest operating pressure setting, re-calibrate Locator, by turning it slightly, in same plane as valve, until the Compass needle does align exactly with the highest or lowest operating pressure setting.


8 - Without moving Locator, remove Compass, then re-insert Magnet, with center line of Magnet aligned with current (highest or lowest) operating pressure setting. Without moving Locator, quickly slide Magnet, with back and forth motion, along the current operating pressure setting axis, and, with Magnet once again centered inside Locator, turn Magnet slowly to new operating pressure setting.


9 - Without moving Locator, remove Magnet vertically, and place Magnet 0.5 meters away from valve.


10 - Without moving Locator, re-insert Compass, confirming that needle is again centered within white target circle, and aligns with new operating pressure setting.
