Abstract: An implantable delivery device for delivering a fluid in a controlled manner, including a body having a chamber, a tube having an inlet and an outlet, at least a portion of the tube passing through the chamber, a drive pinion operatively connected to a motor for rotation, a wheel engaging with the drive pinion, and a ring operatively attached to the wheel, wherein the ring presses against the tube in a pressing zone and is driven by a rotation of the wheel relative to the body such that the pressing zone moves along the tube resulting from the rotation of the wheel to generate a movement of fluid present in the tube from the inlet to the outlet.

Abstract: Apparatus and methods are provided comprising an implantable non-hydraulic ring that encircles and provides a controllable degree of constriction to an organ or duct and an external control that powers and controls operation of the ring. The ring includes a rigid dorsal periphery that maintains a constant exterior diameter, and a compliant constriction system that reduces intolerance phenomena. A high precision, energy efficient mechanical actuator is employed that is telemetrically powered and controlled, and maintains the ring at a selected diameter when the device is unpowered, even for extended periods. The actuator provides a reversible degree of constriction of the organ or duct, which is readily ascertainable without the need for radiographic imaging. Methods of use and implantation also are provided.

Abstract: In one embodiment, a surgically implantable adjustable ring comprises a ring body, which includes a closure system having first and second end parts. The ring body is designed to be closed around a tubular organ by the closure system, constricting the tubular organ by forming a loop.

Abstract: The present invention concerns a surgical ring, configured to be implanted around a biological organ having a pouch or a duct shape. A surgical ring according to the present invention forms a closed loop around the organ, altering its diameter. Variations in ring diameter are reversibly controlled by a system that, in one embodiment, includes a flexible filiform element slidably disposed within the body of the ring and coupled to a first extremity of the ring and also to an actuator disposed near a second extremity of the ring.
