Devices and methods for treatment of obesity

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.

1 - 117 . (canceled)  
   
   
       118 . 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.    
   
   
       119 . The combination of  claim 118 , wherein each of said device and said anchoring frame are configured to be individually implanted in a patient.  
   
   
       120 . The combination of  claim 119 , wherein each of said device and said anchoring frame are configured to be delivered individually over a guidewire.  
   
   
       121 . The combination of  claim 118 , wherein said anchoring frame further comprises a contact surface adapted to contact an internal structure in a patient's body; 
 anchors positioned in said anchoring frame for being driven through said contact surface and into the internal structure; and    a deployment driver slidable under the anchors to drive said anchors through said contact surface, thereby anchoring the anchoring frame to the internal structure.    
   
   
       122 . An anchoring frame for anchoring a device to an internal structure in a patient's body, said frame comprising: 
 an elongated main body having proximal and distal ends;    at least one channel running substantially over a length of said main body;    a contact surface adapted to contact the internal structure in the patient's body;
