Claims9
An implantable fluid valve comprising:
- a plurality of valve parts including an inlet adapted to receive cerebrospinal fluid, an outlet adapted to discharge cerebrospinal fluid, adjustable components disposed in a pathway between said inlet and said outlet for adjusting fluid flow through said pathway, an extremely actuatable pushbutton mechanism, and an unlocking mechanism which interacts with said pushbutton mechanism, and which has a subcutaneously actuatable unlocking element, actuated by externally applied pressure, which must be simultaneously actuated together with actuation of said pushbutton mechanism to allow said pushbutton mechanism to adjust said adjustable components;
- and
