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.

Abstract: The invention involves a surgical ring, designed to be implanted around biological organs comprising a pouch or a duct, so as, on the one hand, to form a closed loop between these two extremities (1, 2), thus forming a first (1) and a second (2) extremity and, on the other hand, to reduce the diameter of the opening of said organ when it is tightened by the ring, said ring comprising a system for reversibly controlling the variation in its diameter, characterized in that said system comprises a flexible fillform element (4), inserted longitudinally with possibility of sliding into the material constituting the body of the ring between the first (1) and second (2) extremities, so as to define a fixed portion (5) connected to the first extremity (1) and a free portion (7) associated with an actuator (8) mounted on the ring near the second extremity (2).

Abstract: The invention involves a surgical ring (1) designed to be implanted around (a) biological organ(s) comprising a pouch or a duct, so as to modify the cross-sectional area of the passage of said organ when it is tightened by the ring, said ring (1) being formed by a flexible band (2) comprising a first and second extremity (3, 4), said flexible band (2) being designed to be closed near its two extremities (3, 4) by a closure system so as to form a closed loop featuring an internal contact surface (2A) with the biological organ and an opposite external surface (2B), characterized in that the closure system features a means of encircling (5) that is integral with the first extremity (3) and arranged to evolve between: a de-latching configuration, where the means of encircling (5) forms an open collar freeing the second extremity (4), and a latching configuration where the means of encircling (5) forms a closed collar designed to surround the second extremity (4) so as to unite it with the first extremity (3),

Abstract: A device for transluminal implantation of a substantially tubular, radially expansible stent. The device includes a central tube surrounded by an outer tube axially displaceable relative to the central tube, with the radial dimensions of the tubes being such as to form an annular space therebetween capable of accommodating the stent in an unexpanded state. The outer tube is axially displaceable relative to the central tube. In one embodiment of the device, the central tube, at a distal end thereof, is provided with a section of reduced diameter at the proximal end of which there is an undercut groove forming a circumferential flange within which a proximal end of the stent rests until release of the stent by rearward displacement of the outer tube.
