1. A method of determining pressure and cam position of an implantable shunt, comprising:
measuring, by a programmable controller, an amount of tension on a resilient member of the implantable shunt, by at least one tension sensor connected to the resilient member that generates tension data corresponding to the measured amount of tension;
transmitting the generated tension data over a communication link, by a transmitting unit;
receiving, by a reading unit the transmitted tension data over the communication link; and
computing both a pressure associated with the implanted shunt and a position of a cam connected to the resilient member, based on the received tension data.
