FLUID CONTROL SYSTEM FOR IMPLANTABLE EXPANDABLE DEVICES

An implantable fluid operated device may include a fluid reservoir configured to contain a fluid, an expandable member, and a pump assembly configured to transfer the fluid between the fluid reservoir and the expandable member. The pump assembly may include one or more fluid pumps and one or more valves. The one or more valves may be normally open valves, normally closed valves, or a combination thereof. One or more sensing devices may be positioned within the fluid channel of the fluid operated device. The electronic control system may control operation of the pump assembly based on fluid pressure measurements and/or fluid flow measurements received from the one or more sensing devices. A variable voltage may be applied to control of the pump and/or valve based on varying atmospheric conditions and fluid pressure and/or flow measurements processed by the electronic control system. 本发明涉及一种可植入的流体操作装置，其可以包括被配置为容纳流体的流体储存器、可膨胀构件和被配置为在流体储存器和可膨胀构件之间转移流体的泵组件。泵组件可以包括一个或更多个流体泵和一个或更多个阀。一个或更多个阀可以是常开阀、常闭阀或其组合。一个或更多个感测装置可
