Abstract
Cerebrospinal fluid is drained from a ventricle of the brain of a fetus and into the amniotic cavity in an antenatal procedure that does not require a hysterotomy, such being carried out by a shunt and introducer system. The introducer portion of the system includes a plurality of components that are slidably assembled and that provide a guiding sheath through which the shunt is passed with the aid of a pushing tool and a stylet that passes through the pushing tool and into the shunt. The hydrocephalus valve within the shunt is radially offset from the longitudinal axis of the shunt in order to permit stylet passage therethrough.
