The present disclosure pertains to therapeutic hydrogels that comprise an anionic polysaccharide crosslinked by a branched polyamine, wherein the branched polyamine comprises at least two primary amine groups, more typically at least three primary amine groups. The present disclosure also pertains to medical compositions that comprise such therapeutic hydrogels and to methods of medical treatment in which such therapeutic hydrogels are delivered to a patient in need of medical treatment.

A sealant syringe assembly includes a first syringe including a plurality of chambers and discharging a first solution which is a mixture of a buffer solution and compound powder; a reaction solution syringe including at least one chamber and discharging a reaction solution capable of reacting with the first solution; and a connector for connecting the first syringe and the reaction solution syringe to mix and discharge the first solution and the reaction solution. The first syringe includes three packing members provided inside the first syringe; a passage provided in the inner circumferential surface of the first syringe; and a plunger for providing a pressure to one of the packing members.

The invention features adhesive devices for holding objects (e.g., bone fragments) fixed with respect to each other.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

The hemostatic material composition contains a polysaccharide having a reactive group that reacts with a protein to form a crosslinking structure, a hydrophobic solvent, and a crosslinked particle containing one or more compounds selected from the group consisting of a crosslinked protein and a crosslinked polysaccharide.

The invention relates to compositions comprised of albumin and clottable proteins including fibrinogen and to use thereof e.g., for treating bleeding. In particular, the compositions are comprised of albumin and one or more clottable proteins, wherein the albumin and the one or more clottable proteins are present at a total concentration of at least 90% by total protein weight, wherein the clottable protein fibronectin is present at an amount of less than about 0.5% by total protein weight or is absent, and wherein the weight ratio of the albumin to the clottable protein fibrinogen is at least 1:15, respectively.

A pasty two-component polymethacrylate bone cement comprising a pasty component A, containing AI at least one distillable methacrylate monomer for radical polymerisation; AII at least one polymer soluble in AI; AIII at least one particulate polymer with a particle size of no more than 500 μm that is not soluble in AI; AIV at least one radical stabiliser; and AV at least one aromatic amine accelerator; and a pasty component B, containing BI dibenzoyl peroxide; BII at least one substance that is not subject to radical polymerisation and is liquid at room temperature, whereby the solubility of dibenzoyl peroxide in this substance at room temperature is less than 5.0% by weight and, whereby the weight fraction of liquid substance BII in the self-curing cement dough is less than 2.0% by weight. Also disclosed is a method for producing a self-curing bone cement dough using the pasty two-component polymethacrylate bone cement.

A biocompatible controlled release form of complexed iodine is achieved by a complexation of polyvinyl alcohol based foam and characterized by a residual starch component to optimize iodine release profiles. The resulting iodine complexed polyvinyl alcohol foam may be utilized locally as an antimicrobial agent that releases controlled amounts of iodine sufficient to kill microbes for extended durations without excessive bulk and rigidity.
