Telemetrically controlled band for regulating functioning of a body organ or duct, and methods of making, implantation and use
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 compressible ventral surface and a substantially rigid dorsal periphery;
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 tension element slidably disposed within the elongated member, the tension element including a compliant portion that permits elastic extension of the tension element; and
a telemetrically-controlled actuator disposed on the second end of the elongated member, the actuator engaging the tension element, operation of the actuator causing the tension element to constrict the loop against a patient'"'"'s body organ or duct, wherein the rigid dorsal periphery of the elongated element and the compliant portion of the tension element cooperate to permit straightening of the elongated element to facilitate passage into a patient'"'"'s abdomen laparoscopically.

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.

41. 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;
a housing disposed on the second end of the elongated member;
an electric motor disposed within the housing;
an actuator disposed within the housing and coupled to the electric motor;
a tension element slidably disposed within the elongated member, the tension element including a compliant portion and a portion defining a helical screw thread, the tension element having a fixed end coupled to the first end of the elongated member and a free end that engages and extends through the actuator, wherein operation of the actuator causes the tension element to vary a diameter of the loop. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)
