Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an elongate body having a cavity at a distal end and a tissue retractor extendable distally from the distal end of the elongate body. The tissue retractor may include an expansion mechanism. The expansion mechanism may include a plurality of arms each having a first end coupled around a distal cap and expandable radially outward from the distal cap such that an anchoring mechanism on a second end of the arms is engageable with selected tissue for resection of the body lumen. The tissue resection device may further include a tissue resecting device.

Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include a body extending along an axis and a distal cap positioned distally of the body and coupled to a shaft extending along the axis. The body and the distal cap may be movable relative to each other. An anchoring mechanism may be capable of engaging the body and the distal cap proximate a selected tissue for resection in the body lumen. A tissue capture device may be deployable from the tissue resection device such that a selected tissue for resection is securable by the tissue capture device. The tissue resection device may further include a tissue resecting device for resecting the selected tissue for resection.

Abstract: A medical device may comprise a handie, a first shaft extending from a distal end of the handle, and a second shaft extending a lumen of the first shaft. The handle may further include a first actuator and a second actuator. The first shaft may include (1) a plurality of lumens extending therethrough, (2) a distal face, and (3) a longitudinal axis. Actuation of the first actuator may articulate a distal portion of the first shaft. The second shaft may be axially movable relative to the first shaft such that the second shaft extends out of a distal opening of the first lumen and distally of the distal face. Actuation of the second actuator may articulate a distal portion of the second shaft.
