Abstract
In one aspect, an implantable shunt system is disclosed that, in one example implementation, includes a resilient member and a connected fluid regulating device. The fluid regulating device selectively permits fluid flow through an opening valve of an implantable shunt according to an adjustable opening pressure. The opening pressure is proportional to an amount of tension on the resilient member. One or more tension sensors that are connected to the resilient member measure an amount of tension on the resilient member. The tension sensors generate tension data that corresponds to the measured amount of tension. The system further includes a communication unit with a transmitting unit that transmits the measured data over a communication link. The system also includes a reading unit that receives the transmitted tension data over the communication link. The reading unit includes a connector that electrically connects the reading unit to the transmission unit.
