Abstract: In some aspects, the present disclosure pertains to a kit for forming a cross-linked hydrogel, the kit comprising a reactive high molecular weight multi-arm polymer comprising a core, a plurality of polymer segments having a first end that is covalently attached to the core and a second end comprising a moiety that comprises a reactive group, wherein the reactive high molecular weight radiopaque multi-arm polymer has a molecular weight of greater than 10,000 Daltons; and a multifunctional compound that comprises functional groups that are reactive with the reactive group of the reactive high molecular weight multi-arm polymer.

Abstract: In some aspects, the present disclosure provides kits for delivering and hydrolyzing crosslinked polysaccharide hydrogels, the kits comprising (a) a hydrogel delivery system configured to deliver a crosslinked polysaccharide hydrogel to a subject, the crosslinked polysaccharide hydrogel comprising polysaccharide molecules that are crosslinked by crosslinks that comprise hydrolysable ester bonds and (b) a hydrogel hydrolysis system configured to deliver a hydrolysis-accelerating catalytic composition to the subject, the hydrolysis-accelerating catalytic composition adapted to accelerate hydrolysis of the hydrolysable ester bonds in the crosslinked polysaccharide hydrogel. In other aspects, the present disclosure provides methods of using the same.

Abstract: In some aspects, the present disclosure pertains to systems for forming hydrogel compositions, the systems comprising a first reservoir containing an iodinated polymer composition that comprise an iodinated polymer having multiple cyclic imide ester groups, a second reservoir containing a buffered diluent solution having a first pH that comprises water, a first buffering agent and a polyamine compound, and a third reservoir containing a buffered accelerant solution having a second pH that is higher than the first pH and comprises water and a second buffering agent. Other aspects of the present disclosure pertain to methods of using such systems for forming hydrogel compositions.

Abstract: Systems for hydrogel hydrolysis as well as methods for hydrogel hydrolysis are disclosed. An example system may include a syringe barrel having a needle connector disposed thereon. A hydrogel hydrolysis material may be disposed in the syringe barrel. The hydrogel hydrolysis material may be configured to be injected into a hydrogel formed in the body of a patient in order to accelerate the hydrolysis of the hydrogel.

Abstract: In one aspect, the invention is directed to a sharpener for sharpening a snowice travel member such as a skate blade, a ski or a snowboard, which includes a sharpening surface that is movable lengthwise along an edge face of the item to be sharpened. The sharpening surface may be movable lengthwise by means of a motor and a reciprocating mechanism, or may be manually moved by a user.
