Abstract: Methods of forming a gel and related methods of treating subjects with such gels are described. The method may include preparing a composition by combining a macromer comprising a first polyethylene glycol (PEG)-based polymer, a poly(ethylenimine)-based polymer, or a poly(1,2-glycerol) carbonate-based polymer, the macromer including at least one first functional moiety, a crosslinking agent comprising a second PEG-based polymer that includes at least one second functional moiety, and a photoinitiator, and activating the photoinitiator via a light source to form the gel.

Abstract: The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to devices, systems, and methods for closing a wound, such as a tissue defect resulting from an endoscopic mucosal resection or endoscopic submucosal dissection procedure. In one example, a device for closing a wound may include a closure element having a delivery configuration and a deployed configuration, the closure element configured to be disposed about an endcap of an endoscope in a delivery configuration. A release filament may have a distal end releasably coupled to the closure element and a proximal end extendable within the endcap. The closure element may be configured to substantially close about the wound in the deployed configuration.

Abstract: A medical dispensing device which includes a catheter, an applicator tip at a distal end of the catheter, the catheter and the applicator tip defining a lumen having a longitudinal axis and a distal opening, a plunger in the lumen and movable along the longitudinal axis, and a plurality of elements in the lumen proximal to the distal opening and distal to the plunger, the plurality of elements stacked along the longitudinal axis for dispersement of one element at a time through the distal opening via a force applied by the plunger.
