Abstract
Methods, devices, tools, instruments and systems for treating a patient to induce weight loss. In one method embodiment, a device, including an expandable member in a collapsed configuration, is passed through an opening in the skin of the patient, and into the abdominal cavity of the patient. At least a portion of the expandable member is anchored relative to at least one structure in the abdominal cavity, without piercing the stomach. The expandable member is expanded to an expanded configuration in a space in the abdominal cavity to perform at least one of: prevention of expansion of the stomach of the patient into the space; and compression of a portion of the stomach.

35. A method of treating a patient, said method comprising:
-
passing a device including an expandable member in a collapsed configuration through an opening in the skin of the patient, and into the abdominal cavity of the patient; anchoring at least one attachment tab extending from the expandable member, relative to at least one structure in the abdominal cavity, without piercing the stomach; and expanding the expandable member to an expanded configuration in a space in the abdominal cavity to perform at least one of;
prevention of expansion of the stomach of the patient into the space; and
compression of a portion of the stomach;wherein the expandable member comprises an elongated tube, said anchoring at least a portion of the expandable member comprises anchoring a distal end portion of the tube, said method further comprising incrementally advancing an additional portion of the tube and placing the additional portion into a desired location;
anchoring the additional portion; and
repeating the incrementally advancing, placing and anchoring the additional portion steps until all of the elongated tube has been placed and anchored in the abdominal cavity.

36. A method of treating a patient, said method comprising:
-
passing a device including an expandable member in a collapsed configuration through an opening in the skin of the patient, and into the abdominal cavity of the patient; anchoring at least one attachment tab extending from the expandable member, relative to at least one structure in the abdominal cavity, without piercing the stomach; and expanding the expandable member to an expanded configuration in a space in the abdominal cavity to perform at least one of;
prevention of expansion of the stomach of the patient into the space; and
compression of a portion of the stomach;wherein the device is passed in a compact configuration, the device being provided with looped tabs, the compact configuration being achieved by rolling the device to align opposite sets of the looped tabs, and inserting a rod or wire through the aligned sets of looped tabs.
