1. A system for constricting a stomach of a patient for treating obesity, the system comprising:
- a gastric band having a first end, a second end, a distal region and a proximal region and a connector configured to couple the first end with the second end such that the gastric band is formable into a loop to circumscribe the stomach;
a membrane disposed between the first end and the second end of the gastric band;
at least one cushion segment coupled to the membrane and disposed on the proximal region of the gastric band; and
a mechanism for enabling adjustment of an inner circumference of the loop, the mechanism comprising an interface connected to the gastric band, and a control capable of communicating with the interface to regulate constriction of the gastric band about the stomach;
wherein the membrane includes at least one support wedge secured to the at least one cushion segment.

Abstract
A system for regulating the functioning of an organ or duct generally includes an implantable band structured to at least partially circumscribe an organ or duct and an actuating mechanism operable to effect constriction of the band. The system further includes a plurality of incompressible cushion segments defining a substantially star-shaped inner circumference of the band, the star-shape effective to prevent pinching and necrosis of tissue during adjustment.

16. A system for constricting a stomach of a patient for treating obesity, the system comprising:
-
a gastric band having a first end, a second end, a distal region and a proximal region and a connector configured to couple the first end with the second end such that the gastric band is formable into a loop to circumscribe the stomach; a contact region disposed between the first end and the second end of the gastric band, an inner circumference of the loop having a generally star-shape defined by the contact region; and a mechanism for enabling adjustment of the inner circumference of the loop; wherein the contact region includes a membrane and at least one cushion segment, the membrane disposed between the first end and the second end of the gastric band, and the at least one cushion segment coupled to the membrane and disposed on the proximal region of the gastric band, the membrane including at least one support wedge secured to the at least one cushion segment. - View Dependent Claims (17, 18, 19)
