Claim Text:
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 configured to be disposed in a body part; an implantable valve coupled to the second open end of the tube and having at least one open state and a closed state wherein the valve further comprises an implantable sleeve having first and second ends and having an orifice extending through a wall of the sleeve, and a blade positioned inside said sleeve, and formed at least in part from a material that is reactive to magnetic force, the blade configured to slide from a first position relative to the sleeve where the blade does not block the orifice and the valve is in the at least one open state, to a second position relative to the sleeve where the blade blocks the orifice and the valve is in at least one closed state, such that a position of the blade relative to the sleeve determines whether the valve is in the at least one open state or the closed state; a first implantable sensor for actively obtaining at least one measurement of pressure within the body part; and an implantable control device electrically coupled with the valve and the sensor, for receiving the at least one measurement and switching the valve between the at least one open state and the closed state based on the at least one measurement, wherein the tube is configured to drain 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, the difference created by native differences in pressure of the body part to another body part.
