<p>The present invention refers to an implantable system for use in a gastric band system comprising: a housing having a fluid inlet/outlet; a flexible reservoir positioned within the housing and coupled to an inflatable portion of a gastric band via the fluid inlet/outlet, the flexible reservoir containing a fluid and having an expanded configuration and a contracted configuration; a movable wall; a driving mechanism; and a motor, coupled to the driving mechanism, the motor capable of actuating the driving mechanism characterized by the movable wall being slidably positioned around the flexible reservoir forming a cylinder, the movable wall being movable to change a diameter of the cylinder, and the driving mechanism positioned around the movable wall, the driving mechanism configured to change the diameter of the cylinder to compress the flexible reservoir from the expanded configuration to the contracted configuration, thereby causing a portion of the fluid in the flexible reservoir to move to the inflatable portion of the gastric band.</p> |
