SiphonX® is an anti-siphon device featuring a ball-in-cone mechanism.
It is placed downstream of a CSF shunting valve for the treatment of hydrocephalus, giving it additional resistance depending on the position of the patient. This makes it possible to limit the siphon effect during CSF drainage when the patient stands up.
Arrow
Shows the direction of CSF flow through the device. This helps to orientate the SiphonX® correctly during implantation.
Rigid body
The device is not affected by the pressure exerted by the sub-cutaneous tissues.
Tantalum weight ball
Calibrated to add 200 mmH20 in the vertical position. Radiopaque for easy location of the device.
