It has been hypothesized, and generally accepted, that the final outcome of the treatment of hydrocephalus is to a great extent related to the earliness of intervention and treatment. However, there is special concern regarding the higher risk of infection and shunt malfunctions in neonates as compared with older infants. Therefore, two new shunt systems have been designed specifically to tip the balance in favor of early shunting. The first shunt is made for premature neonates and the second for neonates in general. The general characteristics of these two shunts are: (1) the entire shunt is a low-pressure valve, with double distal slit valves; (2) the shunts are made of soft silicon material; (3) they are of very small configuration, without any compressing elements which may lead to skin necrosis over the shunt; (4) no metal has been used in them, so they are MRI compatible.
据推测且普遍认为，脑积水治疗的最终结果在很大程度上与干预和治疗的及时性有关。然而，与大龄婴儿相比，新生儿感染和分流器故障的风险更高，这引发了特别关注。因此，专门设计了两种新的分流系统，以促使天平向早期分流倾斜。第一种分流器是为早产新生儿设计的，第二种是为一般新生儿设计的。这两种分流器的总体特点是：（1）整个分流器是低压阀，带有双远端裂隙阀；（2）分流器由柔软的硅材料制成；（3）它们的结构非常小，没有任何可能导致分流器上方皮肤坏死的压缩元件；（4）其中未使用金属，因此它们与磁共振成像兼容。
