Abstract
A bladder assembly is provided in order to maintain the pressure in the balloon portion of a gastric band in a range corresponding to a so-called Green Zone. Multiple bladders are connected by flexible tubing which is connected at a distal end to the balloon portion of a gastric band. The elastically expandable bladders provide fluid pressure on the balloon portion of the gastric band in order to maintain the intra-luminal pressure within a desired range over a prescribed fill volume. A flow restrictor is positioned between the balloon portion and the bladders to restrict fluid flow from the balloon to the bladders during patient swallowing.

59. A method for treating a patient having a gastric band assembly, comprising:
-
providing a gastric band assembly having a gastric band and a balloon, the balloon encircling stomach tissue to form a stoma; further providing one or more bladders in fluid communication with a flow restrictor, the flow restrictor being in fluid communication with the balloon; and the flow restrictor blocking fluid flow from the balloon to the one or more bladders in response to high pressure fluid surges in the balloon. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

70. A method for treating a patient having a gastric band assembly, comprising:
-
providing a gastric band assembly having a gastric band and a balloon, the balloon encircling stomach tissue to form a stoma; further providing one or more bladders in fluid communication with a flow restrictor, the flow restrictor being in fluid communication with the balloon; and the flow restrictor impeding fluid flow from the balloon to the one or more bladders in response to high pressure fluid surges in the balloon. - View Dependent Claims (71, 72, 73, 74, 75, 76, 77, 78, 79, 80)

81. A method for treating a patient having a gastric band assembly, comprising:
-
providing a gastric band assembly having a gastric band and a balloon, the balloon encircling stomach tissue to form a stoma; further providing one or more bladders in fluid communication with a flow restrictor, the flow restrictor being in fluid communication with the balloon; and generating high pressure fluid surges in the balloon due to patient swallowing so that the flow restrictor blocks fluid flow from the balloon to the one or more bladders in response to the high pressure fluid surges in the balloon. - View Dependent Claims (82, 83, 84, 85, 86, 87, 88, 89, 90, 91)

92. A method for treating a patient having a gastric band assembly, comprising:
-
providing a gastric band assembly having a gastric band and a balloon, the balloon encircling stomach tissue to form a stoma; further providing one or more bladders in fluid communication with a flow restrictor, the flow restrictor being in fluid communication with the balloon; and the flow restrictor blocking fluid flow through a main flow channel from the balloon to the one or more bladders in response to high pressure fluid surges in the balloon while allowing fluid flow through a bypass channel. - View Dependent Claims (93, 94, 95, 96, 97, 98, 99, 100, 101, 102)

103. A method for treating a patient having a gastric band assembly, comprising:
-
providing a gastric band assembly having a gastric band and a balloon, the balloon encircling stomach tissue to form a stoma; further providing one or more bladders in fluid communication with a flow restrictor, the flow restrictor being in fluid communication with the balloon; and generating high intra-band pressure fluid surges in the balloon due to food being stuck in area above the band during patient swallowing so that the flow restrictor blocks fluid flow through a main flow channel from the balloon to the one or more bladders in response to the high pressure fluid surges in the balloon while allowing fluid flow through a bypass channel in the flow restrictor to flow from the balloon to the one or more bladders so that the stoma diameter increases and the food can pass. - View Dependent Claims (104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116)
