Abstract: The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to devices, systems, and methods for securing tissue, such as a tissue defect or wound resulting from an endoscopic procedure, e.g., an endoscopic mucosal resection or submucosal dissection procedure. In one example, a device for securing tissue may include a loop portion configured to be disposed about a distal end of a delivery device in a delivery configuration and configured to be secured about the tissue in a deployed configuration. A locking member may be disposed on the loop portion. A tether portion having a proximal end extendable proximally within the delivery device and a distal portion extending from the loop portion slidably through the locking member.

Abstract: A delivery device may be configured to deliver an agent to a target tissue through a channel of a medical device, the delivery device may include a body including (a) a coupling region configured to removably attach to a handle of the medical device, and (b) a coupler including an exit port for aligning with a port of the channel, wherein the coupler is configured to mate with the port of the channel; a source of an agent; and a source of pressurized fluid. The body, the source of agent, and the source of pressurized fluid may be arranged to deliver agent and pressurized fluid to the exit port for delivery through the channel.

Abstract: In one aspect of the present disclosure, an apparatus for delivering a powdered agent into a subject's body may include a powder chamber housing the powdered agent. The apparatus also may include a chassis in fluid connection with the powder chamber. The chassis may include a first passage for receiving a pressurized gas, a second passage for receiving the powdered agent from the powder chamber, and a junction in fluid communication with the first passage and the second passage. At least a first portion of the pressurized gas is introduced into the powdered agent at the junction to fluidize the powdered agent.

Abstract: A tissue-manipulating system including a tissue-manipulating device having shaft and a tissue grasper assembly. The tissue grasper assembly has at least one grasper arm resiliently expandable from a closed configuration, within and extending along the longitudinal axis of a shaft, to an open configuration outside the shaft with the grasper arm expanded in a direction transverse to the longitudinal axis of the shaft. In the open configuration, the at least one grasper arm may be engaged with tissue wall to manipulate or move the tissue wall, such as to move a distal tissue wall closer to a proximal tissue wall. The tissue grasper assembly may be deployable (such as by being separated from the shaft), such as to remain in place holding two tissue walls in apposition.

Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.

Abstract: Systems and methods of delivering a patch to a target site of a patient are described herein. The patch may comprise a biomaterial such as chitosan or extracellular matrix and may be biocompatible and/or bioresorbable. The system may include an endoscope, a patch, and one of an instrument or a cap, the patch being coupled to the respective instrument or cap and detachable therefrom. Methods of delivering the patch to the target site may include introducing an endoscope into a gastrointestinal tract of a patient, e.g., the patch being in a folded or crimped configuration, navigating a distal end of the endoscope proximate a target site; and applying the patch to the target site while releasing the patch from the endoscope.

Abstract: This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.
