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: According to one aspect, a medical device including a needle configured for use in suturing tissue. The needle may include a cylindrical body having a longitudinal axis extending between first and second ends of the cylindrical body. The needle may also include a lumen extending through the cylindrical body transverse to the longitudinal axis. The needle may further include a first end portion at the first end of the cylindrical body. The first end portion may include a sharp point configured to pierce tissue. An outer surface of the cylindrical body may define a first recess in communication with an opening of the lumen and configured to receive an end of a suture.

Abstract: According to one aspect, a medical device including a shaft having a proximal and a distal end. The medical device may also include a handle coupled to the proximal end of the shaft. The medical device may further include a body at the distal end of the shaft. The body may have a wall defining a lumen within the body, and the lumen may have a longitudinal axis. The wall may include a protrusion at the distal end of the body, and the protrusion may be defined by a gap in the wall and may have a sharp portion configured to grasp tissue. The gap may extend proximally from the distal end of the body, and edges of the wall defining the gap may be transverse to the longitudinal axis.

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.
