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. The first end part is shaped like a sleeve having a first and second end portions, and is designed to receive the second end part of the ring. The sleeve is substantially perpendicular to the main direction of the first end part of the ring, and the second end part of the ring includes a locking protrusion adapted to hold the sleeve in position, securing the ring in a closed position by engaging the locking protrusion in an opening disposed on the sleeve.

Closure system for tubular organs

The implantable drug delivery device comprises at least an implantable pump, a reservoir and a delivery chamber.

Implantable drug delivery device

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.

Surgical ring featuring a reversible diameter remote control system

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.

Telemetrically controlled band for regulating functioning of a body organ or duct, and methods of making, implantation and use

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 (), thus forming a first () and a second () extremity and, on the other hand, to reduce the diameter of the opening of the organ when it is tightened by the ring, the ring including a system for reversibly controlling the variation in its diameter. The system also includes a flexible filiform element (), inserted longitudinally with possibility of sliding into the material constituting the body of the ring between the first () and second () extremities, so as to define a fixed portion () connected to the first extremity () and a free portion () associated with an actuator () mounted on the ring near the second extremity ().

A surgical ring () designed to be implanted around (a) biological organ(s), the ring () being formed by a flexible band () including a first and second extremity (), the flexible band () being designed to be closed near its two extremities () by a closure system so as to form a closed loop featuring an internal contact surface (A) external 10 surface (B). The closure system includes a means of encircling () that is integral with the first extremity () and arranged to evolve between a de-latching configuration, where the means of encircling () forms an open collar freeing the second extremity (), and a latching configuration where the means of encircling () forms a closed collar designed to surround the second extremity () so as to unite it with the first extremity (), the closed collar having opposite front () and rear () faces, between which an encircling opening extends that is designed to accept the second extremity ().
