1. An 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, wherein a dorsal periphery of the elongated member is reinforced to prevent a diametral variation of the dorsal periphery.

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.

2. An 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; and
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, and wherein the elongated member is reinforced on the dorsal periphery to prevent diametral expansion of the dorsal periphery of the elongated member.
