Abstract
In some embodiments, an extragastric balloon is described in which the balloon is contoured to fit a portion of the stomach but not circumscribe the stomach. In some embodiments, the extragastric balloon comprises multiple material components. In some embodiments, the extragastric balloon comprises multiple inflateable compartments. In some embodiments, the extragastric balloon is filled with one or more of a gas, liquid, solid, or foams to create portions of the balloon with differing densities or buoyancies. In some embodiments, multiple anchors contact the stomach each of which are inflateable with a fluid such as a liquid, gas, or gel.
Claims16
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 a portion of 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.
A method of treating a patient, said method comprising the steps of:
- passing an anchoring frame into the abdominal cavity of the patient;
- delivering anchoring members, attached to the anchoring frame, through at least one structure in the abdominal cavity that the anchoring frame is to be anchored to, through the skin and out of the patient;
- fixing the anchoring members externally of the abdominal cavity to anchor the anchoring frame to the at least one structure in the abdominal cavity;
- passing a device into the abdominal cavity;
- and attaching the device to the anchoring frame.
In combination, an implantable device engaged with an anchoring frame;
- said implantable device comprising an expandable member having at least one key extending therefrom or groove formed therein;
- said anchoring frame comprising an elongated main body having proximal and distal ends, and at least one channel or rail running substantially over a length of said main body;
- wherein said rail is receivable in said groove and said at least one key is receivable in said channel to mechanically connect said device with said anchoring frame.
An implantable device for treatment of a patient to assist weight loss, said device comprising:
- an expandable member configured to be positioned in an abdominal cavity of the patient, said expandable member configured to be expanded from a contracted configuration to an expanded configuration after placement of said device in the abdominal cavity, and to substantially maintain a size and shape of said expanded configuration, wherein said expandable member comprises a first material and a first region;
- a second member comprising a second material and a second region.
A method of implanting a weight-loss treatment device by connecting the device to an anchoring frame, said method comprising:
- passing the anchoring frame into the abdominal cavity of the patient;
- passing the device, including an expandable member in a collapsed configuration, into the abdominal cavity of the patient;
- and passing the device over the anchoring frame to mechanically lock the device to the anchoring frame and to anchor the anchoring frame to at leas one structure in the abdominal cavity, without piercing the stomach.
A method of implanting a weight-loss treatment device by connecting the device to an anchoring frame, said method comprising:
- passing the anchoring frame into the abdominal cavity of the patient;
- anchoring the anchoring frame to at least one structure in the abdominal cavity, without piercing the stomach;
- passing the device, including an expandable member in a compressed configuration, into the abdominal cavity of the patient;
- and passing the device over the anchoring frame to anchor the device to the anchoring frame.
