Abstract
An implantable shunt that includes one or more catheters configured so that the implantable shunt has a resistance to flow greater than about 3 mm Hg/mL/minute. An implantable shunt system that includes one or more catheters and a fluid control device that utilizes the properties of the catheters to improve the expected function of the shunt by providing a higher or lower resistance to the flow through the shunt and reduces the effect of pulsations of cerebrospinal fluid on the shunt system.
