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 endoscope and a backstop delivery device extendable through the endoscope. The backstop delivery device may deliver a backstop to a location of selected tissue for resection. A backstop may include a covering being deployable in a patient. The covering may have one or more anchoring mechanisms disposed on an edge of the covering. A tissue resecting device may be extendable through the endoscope for resecting the selected tissue for resection. The covering may be deployable to an outer surface of the body lumen, such that the anchoring mechanism may secure the covering to the outer surface of the body lumen and the covering may expand to cover the selected tissue for resection.

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: This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes a scaffold including a central member and a plurality of extension members extending away from the central member. The central member includes a plurality of discrete attachment locations corresponding to each of the plurality of extension members and each of the plurality of extension members is pivotably coupled to the central member at a corresponding discrete attachment location. The medical device also includes a covering substantially surrounding the scaffold and an electrode located at a distal end of each of the plurality of extension members. Each electrode extends through at least a portion of the covering.

Abstract: Methods and devices for locating and dilating a stricture are disclosed herein. In some embodiments, a device for locating strictures comprises an elongate member having a proximal end and a distal end. In at least some additional embodiments, a stopper is attached to the distal end of the elongate member. Additionally, in at least some examples, distance markings are disposed on the elongate member.
