FLOW CONTROL METHOD AND DEVICE
First Claim
1. A laparoscopically implanted adjustable gastric banding device for encircling a stomach of a patient for the treatment of obesity, comprising:
- an elongated member having a first end and a second end, the elongated member configured to make atraumatic contact with the stomach of the patient when encircling the stomach;
a clip disposed on the first end of the elongated member, the clip having a slot and a tab; and
a flange disposed on the second end of the elongated member, the flange configured to engage the slot so that the elongated member encircles an upper part of the stomach of the patient to form a stoma;
wherein the elongated member for encircling the stomach is configured to have an adjustable interior diameter facing the stomach and an exterior diameter facing away from the stomach, the exterior diameter configured to resist changing when the interior diameter is adjusted.

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.

5. A method of laparoscopically implanting a gastric banding device within an abdominal cavity and around a stomach of a patient, the method comprising:
-
providing a gastric banding device having an elongated member, the elongated member having a first end and a second end, the first end having a slot, the second end having a flange configured to engage the slot so that the elongated member encircles the stomach of the patient, wherein the elongated member encircling the stomach has an adjustable interior diameter facing the stomach and an exterior diameter facing away from the stomach, the exterior diameter configured to resist changing when the interior diameter is adjusted; creating a plurality of incisions into the abdominal cavity of the patient; establishing a pneumoperitoneum by insufflating the abdominal cavity of the patient; inserting a tool into at least one of the plurality of incisions to create a path for the elongated member around the stomach; inserting the elongated member into the abdominal cavity; positioning the elongated member around the stomach of the patient; and engaging the flange on the second end of the elongated member with the slot on the first end of the elongated member for wrapping the elongated member around an upper part of the stomach to form a stoma. - View Dependent Claims (6, 7, 8, 9, 10)

11. A laparoscopically implanted adjustable gastric banding device for encircling a stomach of a patient for the treatment of obesity, comprising:
-
an elongated member having a first end and a second end, the elongated member configured to make atraumatic contact with the stomach of the patient along an interior diameter of the elongated member when encircling the stomach; a clip disposed on the first end of the elongated member, the clip having a slot; a flange disposed on the second end of the elongated member, the flange configured to engage the slot so that the elongated member encircles an upper part of the stomach of the patient to form a stoma; and an antenna coupled to the elongated member for enabling telemetric control of the interior diameter of the elongated member; wherein the elongated member for encircling the stomach is configured to have an exterior diameter facing away from the stomach that resists changes in size during adjustment of the interior diameter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
