Surgical ring featuring a reversible diameter remote control system
First Claim
1. Apparatus for regulating the functioning of a patient'"'"'s organ or duct, comprising:
- an elongated member having first end and second ends, the elongated member having a substantially smooth, atraumatic ventral surface;
a clip disposed on the first end of the elongated member, the clip configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct;
a flexible element slidably disposed within the elongated member, the flexible element defining a helical screw thread; and
a telemetrically-controlled actuator disposed on the second end of the elongated member, the actuator having a nut that engages the helical screw thread, operation of the actuator causing the nut to draw the helical screw thread therethrough, whereby the flexible element constricts the loop against the patient'"'"'s body organ or duct.

Abstract
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 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 (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).

19. Apparatus for gastric banding of a patient'"'"'s stomach, comprising:
-
an elongated member having first end and second ends, the elongated member having a compressible ventral surface and a substantially rigid dorsal periphery and configured to be formed into a loop around a portion of a patient'"'"'s stomach; an electric motor disposed on the second end of the elongated member; a nut actuator coupled to the electric motor; a flexible element slidably disposed within the elongated member, the flexible element defining a helical screw thread, the flexible element having a fixed end coupled to the first end of the elongated member and a free end that engages and extends through the nut actuator, wherein operation of the nut actuator draws the helical screw thread through the nut actuator and causes the flexible element to vary a diameter of the loop. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
