Abstract

Methods, devices, tools and assemblies for treating a patient to effect weight loss. One method embodiment involves passing a device including an expandable member in a collapsed configuration and a buoyancy member through an opening in the skin of a patient and into the abdominal cavity of the patient, and anchoring at least a portion of the expandable member, relative to at least one structure in the abdominal cavity. Devices including at least one expandable member and at least one buoyancy member are provided.

Claims

1-95. -95. (canceled)

96. A method of treating a patient, said method comprising:

passing a device into the abdominal cavity of the patient;

anchoring at least a portion of the device, relative to at least one structure in the abdominal cavity; and

occupying a space in the abdominal cavity with the device to substantially restrict expansion of the fundus of the stomach, and restraining the stomach to a shape resembling a tube, but wherein at least a portion of the antrum is left unrestrained.

97. The method of claim 96, wherein a small pouch is also left unrestrained at a superior end portion of the stomach.

98. A method of treating a patient, said method comprising:

passing a device into the abdominal cavity of the patient;

anchoring at least a portion of the device, relative to at least one structure in the abdominal cavity; and

occupying a space in the abdominal cavity with the device to substantially restrict expansion of the fundus of the stomach, and restraining the stomach to a shape resembling a tube, but wherein a small pouch is left unrestrained at a superior end portion of the stomach.
