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.
Claims28
A bougie for shaping a wall of a body cavity to receive longitudinally extending suturing from within the bougie, and configured for release of the sutured portion after suturing, comprising:
- (a) a lumenal wall;
- (b) a wall opening open to the exterior of the bougie, configured to receive suction from within the bougie, and extending longitudinally along the lumenal wall;
- (c) at least one longitudinally extended construction bendable with a bending radius of 1-2 mm or less passing laterally between two regions of the bougie to act as a blocker, the bendable blocker occupying a blocking position dividing the wall opening into a plurality of longitudinally separated fenestrations;
- and
- (d) a release mechanism operable to release the blocker from the blocking position to allow release of the longitudinally extending suturing extending across the blocker from the bougie including from the blocker.

A bougie for shaping a body cavity portion to receive longitudinally extending suturing from within the bougie, and configured for release of the sutured portion after suturing, comprising:
- a plurality of fenestrations along a wall of the bougie, the fenestrations being configured for receiving gastric wall tissue for suturing upon the application of suction from within the bougie wall;
- and
- at least one longitudinally extended construction bendable with a bending radius of 1-2 mm or less, positioned to act as a blocker defining a separation between a pair of the fenestrations.
24-25. (canceled)
A method of intralumenally suturing a gastric sleeve, comprising:
- inserting into a stomach a bougie having a wall comprising a plurality of fenestrations longitudinally divided from one another by a longitudinally extended construction bendable with a bending radius of 1-2 mm or less and acting as a transverse blocker;
- suturing tissue from opposing sides of the stomach to each other through the fenestrations, wherein the suture crosses at least one transverse blocker where the suture extends within the bougie;
- and
- opening a gap between a pair of the plurality of fenestrations where the suture crosses the transverse blocker, wherein opening the gap comprises releasing the transverse blocker from at least one attachment to the bougie.
