Programmable Shunt

COMPONENTS

ACCURACY WITH THE ADJUSTMENT MECHANISM

During the adjustment, the rotor movement changes the distance between the rotor axis and the Sphera mechanism (spring, sphera and conical ruby seat), increasing or decreasing the valve pressure. The precise rotor radius dimensional control allows the accurate definition of the 08 different levels of opening and closing pressures, providing a real intracranial pressure control when the pressure adjustment is performed.

SECURITY AGAINST DEPROGRAMMING

With a unique design, the valve rotor has two mechanical safety locks that moves in opposite directions, and may have double or single locking against non-intentional deprogramming. Each lock is located on a magnet and is pushed against a pressure position by the action of a spring.

When the magnetic fields from the environment, or an unilateral one (generated by MRI), are able to move one of the magnets and release one of the latches, the other is forced by the same fields to remain in the locking position, avoiding deprogramming of the valve.

ANTIGRAVITY DEVICE

Hiperdrainage control

The antigravity device Sphera Grav provides overdrainage control by performing automatic compensation for the system’s opening pressure as the patient postural changes.

When the patient is in the supine position, no resistance will be built by Sphera Grav, only the Sphera Pro valve will be active.

However, when the patient is in the orthostatic position, the maximum resistance of Sphera Grav will act along with the Sphera Pro adjustment pressure, making the shunt system more physiological and maintaining the intraventricular pressure more constant and with less risks of overdrainage.

Sphera Grav has 06 resistance options (10, 15, 20, 25, 30 or 35 cmH2O) to meet the different needs of pressure control for each patient. The device consists of tungsten and ruby spheres, polysulphone body, titanium connectors and silicone coating.

EASY PRESSURE ADJUSTMENT

The programming device allows an easy pressure adjustment as it provides easy valve location, painless to the patient and immediate confirmation of the adjusted pressure, eliminating the necessity of image exams.

Since the correct programming device centralization upon the valve is essential to the unlocking and pressure adjustment, the reader has an indication aligment system that confirms the right position.

STEP 01

Set whether to reduce or increase the pressure by turning the top of the programmer counterclockwise or clockwise, until the indicator pin is in the "-" or "+" position.

STEP 02

With the compass placed on the positioner, locate the valve.
Align the positioner flow indication arrow with the peritoneal catheter path.
By moving the positioner around the valve, align the center of the pointer with the center of the compass.
While moving the compass, in both directions, the pointer must remain still.
Perform the reading.

the incorrect position

Centered pointer:

the correct position

STEP 03

Keep the positioner on the same site and insert the programmer on the place of the compass. Turn counterclockwise to increase the pressure and clockwise to decrease the pressure.

STEP 04

Replace the programmer for the compass. Perform the reading of the new pressure, keeping the pointer center aligned with the center of the compass.
