Patent ID: 8657885

Claim:
A device for insertion within a stomach of a patient, comprising: an elongated bridging member detachable from a delivery device and having a proximal end and a distal end; a proximal occlusion member coupled to a proximal end of the bridging member and sized to have a first diameter for anchoring within the stomach without passage through a pyloric valve, wherein the proximal occlusion member having a first portion thereof that is reconfigurable from a low-profile delivery configuration to an expanded deployment configuration having the first diameter; and a distal occlusion member coupled to the bridging member at a distance from the proximal occlusion member such that the distal occlusion member is positioned within the intestinal tract, the distal occlusion member having a non-expandable configuration with a second diameter which is smaller than the first diameter such that the distal occlusion member is non-expandable after deployment, wherein the proximal occlusion member having the first portion surrounding forms a non-inflated or solid structure, more rigid than said first portion, which defines a hollow portion within in its deployment configuration and which is larger than the distal occlusion member, and where the bridging member comprises a flexible length sufficient to extend through the pyloric valve of the patient such that the proximal occlusion member is proximally translatable relative to the pyloric valve and a passage between the bridging member and the pyloric valve is opened intermittently while the distal occlusion member is flexibly maintained within the intestinal tract.
