Abstract: In some examples, a catheter includes an elongated body and an expandable member at a distal portion of the elongated body and defining at least part of a distal tip of the catheter. The expandable member is formed from materials that enable a distal tip of the catheter to be radiopaque without the addition of a separate radiopaque marker (e.g., a solid metal ring of radiopaque material separate from and connected to the elongated body) at the distal tip of the catheter.

Abstract: Compositions and methods for treating vascular defects are provided. In some embodiments, a hydrogel composition for treating a vascular defect includes a plurality of silicate nanoparticles, where each silicate nanoparticle includes a cationic portion and an anionic portion, and where the silicate nanoparticles are non-covalently crosslinked with each other via electrostatic interactions between the cationic portions and the anionic portions of the silicate nanoparticles; and a synthetic polymer comprising an anionic functional group, where the synthetic polymer is non-covalently crosslinked with the plurality of silicate nanoparticles via electrostatic interactions between the anionic functional group of the synthetic polymer and the cationic portions of the silicate nanoparticles.

Abstract: A catheter includes an elongated body including a distal body portion and defining a body inner lumen. The catheter includes an expandable member coupled to and extending from the distal body portion. The expandable member includes an expandable support member and a polymer jacket. The expandable member defines an expandable member inner lumen. The expandable member inner lumen is in fluid communication with the body inner lumen. The expandable support member includes a tubular body and is configured to self-expand to expand the expandable member inner lumen radially outward. The polymer jacket at least partially overlays the expandable support member. The polymer jacket includes polymer loaded with a radiographic material, and the radiographic material configured to be visible via medical imaging.

Abstract: Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.

Abstract: Medical articles include a substrate with a layer of a siloxane-based gel adhesive composition. The gel adhesive composition includes a crosslinked polymeric siloxane matrix, and an extractable polymeric fluid with a weight average molecular weight greater than 275,000 grams/mole. The extractable polymeric fluid is 26-80 weight % of the gel adhesive composition. The gel adhesive composition may also include a siloxane tackifying resin.

Abstract: Polymeric materials are disclosed herein that include a Polymer A, a Polymer B, and an oxalate ester or reaction product thereof. Polymer A contains electrophilic reactive groups, and Polymer B contains nucleophilic groups. In certain embodiments, the polymeric materials are free-flowing liquids at 100% solids that can be used, for example, as topical skin adhesives.
