1. A system for controlling pressure in a body part, comprising:

  • an implantable tube, having a first open end and a second open end, the first open end disposed in a body part;

    an implantable valve coupled with the tube and having at least one open state and a closed state;

    a first implantable sensor configured to obtain at least one measurement of pressure within the body part; and

    an implantable control device coupled with the valve and the sensor, and configured to receive the at least one measurement and to switch the valve between the at least one open state and the closed state based on the at least one measurement,wherein the tube drains fluids from the body part when the valve is in the at least one open state, due to a difference of pressure between the first and the second open end of the tube, this difference created by the native differences in pressure of the body parts or through the use of an implantable pump in the device.
