Abstract
Devices and methods of endolumenal formation of gastric sleeves are described. Some embodiments allow templating of a gastric sleeve by a gastric bougie, exposing a selected amount of tissue for suturing access, while maintaining sufficient internal working space for suturing within the template lumen.
Claims25
A bougie for shaping a stomach portion to receive sutures, comprising:
- a body comprising a bendable portion and a lumen;
- a plurality of fenestrations to said lumen within said bendable portion of said body;
- a blocker coupled to said body and moveable with respect to said body and said plurality of fenestrations within said body, and comprising a portion positionable with respect to said body to:
- divide said plurality of fenestrations, each into two portions;
- and
- be moved to merge said two portions, after suturing, thereby allowing release of said bougie from sutures crossing between said fenestration portions and crossing said blocker inside said lumen.

- a plurality of fenestrations to said lumen within said body, and
- a blocker coupled to said body and moveable with respect to said body and said plurality of fenestrations;
- wherein said blocker comprises a portion positionable with respect to said body to:
- divide said plurality of fenestrations, each into two respective portions, and
- be moved to merge said two respective portions;
- drawing vacuum through said bougie, such that stomach tissue is drawn to said body, wrapped around said body, and partially intruded into said plurality of fenestrations;
- and
- moving said blocker to gradually one or more of:
