Support device for gastrointestinal implant
First Claim
1. A support device for a gastrointestinal implant, the support device comprising:
- a lumen configured to extend through a submucosal tunnel;
a mouth located at a proximal end of the lumen and in fluid communication with the lumen, wherein the mouth is configured to face proximally within a gastrointestinal tract to receive GI contents, and wherein the mouth is configured to direct the GI contents into the lumen;
a support structure, wherein the lumen extends through the support structure, and wherein the support structure is configured to apply an outward radial force on an inner wall of the gastrointestinal tract; and
an artificial tunnel extending distally from the support structure and forming at least a portion of the lumen, wherein the artificial tunnel is configured to extend through the submucosal tunnel.

Abstract
The present disclosure provides a support device for a gastrointestinal implant. The support device may include a lumen configured to extend through a submucosal tunnel and a mouth located at a proximal end of the lumen and in fluid communication with the lumen. The mouth may be configured to face proximally within a gastrointestinal tract to receive GI contents, and the mouth may be configured to direct the GI contents into the lumen. The support device may further include a support structure, where the lumen extends through the support structure, and where the support structure is configured to apply an outward radial force on an inner wall of the gastrointestinal tract. An artificial tunnel may extend distally from the support structure, may form at least a portion of the lumen, and may be configured to extend through the submucosal tunnel.

15. A method for forming a bypass of a portion of a gastrointestinal tract, the method comprising:
-
injecting a fluid beneath a first layer to separate the first layer from a second layer, thereby forming a fluid-filled pocket; forming a first incision at a proximal end portion of the fluid-filled pocket; and forming a second incision in a distal end portion of the fluid-filled pocket, wherein the first incision, second incision, and pocket define a tunnel. - View Dependent Claims (16, 17, 18, 19, 20)
