Abstract: The present disclosure relates generally to apparatuses, devices, and methods for performing endoscopic tissue resectioning in the gastrointestinal tract. In some embodiments, a tissue resectioning device may include first and second scaffolds each arranged in a tubular configuration. The tissue resectioning device may further include a hook tool engageable with the first scaffold and/or the second scaffold to bias the scaffolds to engage a target section of tissue between the first scaffold and the second scaffold. The hook tool may also engage the section of tissue to pull the section of tissue into the path of a cutting edge of each of the first and second scaffolds. In some embodiments, the tissue resectioning device is provided over a scope, which extends within a lumen of an overtube.
