Patent ID: 8663338

Claim:
An intestinal insertion device, comprising: an elongated connecting member detachable from a delivery device and having a proximal end and a distal end, wherein the connecting member has a length which is configured to be placed within and follow a portion of an intestinal tract and where the connecting member also has a diameter which is sized to freely slide through a pyloric valve; a proximal occlusion member coupled to the proximal end and having a first portion thereof that reconfigurable from a low-profile delivery shape to an expanded deployment shape which is sized for anchoring within the stomach, wherein the proximal occlusion member comprises a support portion proximal to a tissue contact portion which is positioned adjacent to the connecting member, the support portion being relatively stiffer than the tissue contact portion such that a shape of the support portion is maintained when in a deployed configuration; a distal occlusion member coupled to a distal end of the connecting member and having a size which is smaller than the expanded deployment shape of the proximal occlusion member such that the distal occlusion member is non-expandable after deployment, where the distal occlusion member is sized to be slidably positionable relative to the intestinal tract, wherein the proximal occlusion member having the first portion surrounding 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 one or more releasable bioactive materials incorporated along the device.
