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.

Systems, methods and kits for treating hemorrhages within cavities are provided. The methods utilize the application of a rapid spike of pressure to the closed cavity, followed by a steady state pressure or pressures.

The present disclosure relates to methods and compositions for the treatment of degenerate bone in a patient. In some embodiments, the methods and compositions disclosed herein are useful in the treatment, prevention, or in delaying the progression of a bone disease linked to bone degeneration, such as osteoarthritis (“OA”), rheumatoid arthritis, and avascular necrosis.

The present invention relates generally to agents and devices for promoting hemostasis and, more particularly, to bioresorbable hemostatic pads or patches releasably supported on non-resorbable scaffolds for ease of delivery in the field. A sealant and/or hemostat delivery device comprises a resorbable hemostatic pad having a wound facing side and an opposite back side, with a hemostatic and/or wound sealing agent disposed on the wound facing side; a non-resorbable scaffold having an attachment zone on said scaffold; wherein said hemostatic pad is releasably attached with the back side to the attachment zone. The bond between the scaffold and the resorbable hemostatic pad or wound dressing is either (i) severed prior to removal of the scaffold or (ii) is weakened due to the adhesive bonding them together being moisture-deactivated, or (iii) is released by mechanical disentanglement.

The present chitosan-based superfine fiber invention relates to compositions, formulations, and processes that result in numerous significant advantages for the production and use of superfine fiber bioactive matrices in biomedical applications. The present invention relates to superfine, chitosan-based fibers, wherein the chitosan-based fibers have a percentage chitosan content of at least about 20% w/w, and highly conformable and compliant matrices comprising such fibers, processes for their production, and related formulations. The superfine chitosan-based fibers of the invention preferably include microfibers with diameter less than or equal to about 10 microns and micron and submicron fibers that are about 2 microns and less.

The present disclosure belongs to the technical field of hemostatic materials, and specifically relates to a degradable hemostatic sponge and a preparation method and use thereof, and a degradable drug-loaded hemostatic sponge. The degradable hemostatic sponge provided by the present disclosure is prepared from raw materials including a crosslinking-modified starch and a cellulose through freeze-drying, where a mass ratio of the crosslinking-modified starch to the cellulose is (0.2-5):1. The degradable hemostatic sponge provided by the present disclosure has a high water-absorbing rate and a large water-absorbing capacity, shows a high support strength and a long support time after water absorption, and is made from plant-derived raw materials and thus may be completely biodegraded. The degradable drug-loaded starch hemostatic sponge provided by the present disclosure has a drug-loaded coating attached to a surface of the sponge, where the drug is slowly released while a support is maintained.

The invention relates to porous absorbent Composite Material, which may be used e.g. in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides a hydrophilic Self-Dispersive, fragmentable and Bio-Absorbable Porous Composite foams, suitable for packing antrum or other cavities of the body, comprising of composite of polymers, which polymer preferably comprises —C(O)—O—; NH2/3+; —OH; —CH2OCH2C(O)O— groups as functional or —CH—O— (e.g. C2H4O; C6H10O5; C6H8O6); —CH—N—O— (e.g. C8H13NO5); O—C—C— (e.g. O—CH2-CH2); —C(O)N— groups in the backbone of the polymers e.g. gelatin, chitosan, collagen, alginate, polyvinyl alcohol, polyethylene glycol, keratin, cellulose.

Disclosed is abase plate 1 for an ostomy collection device, comprising a cover layer 2 whereon an adhesive layer 3 is at least partly disposed. Immediately surrounding a through-going hole 6, the base plate has an inner area wherein the cover layer extends beyond the adhesive layer in a radial direction toward the through-going hole, thereby providing an overlap 7 protecting the adhesive material from contact with stomal output.

Systems and methods for preparing synthetic osteoinductive bone grafts are provided in which a porous ceramic granule, which may be incorporated within a biocompatible matrix material, is loaded with an osteoinductive agent. Loading of granules is facilitated in some cases by the use of low-pH buffers and pre-treatments.

A medical adhesive and the preparation method, and application thereof. The medical adhesive is in the form of a gel, which contains a giant salamander skin mucus and an aqueous solution; the ratio parts by weight of the giant salamander skin dried powder and the aqueous solution is 1:1 to 1:6, and the weight content of the giant salamander skin mucus freeze-dried powder in the medical adhesive ranges from 14.2% to 50%. The present invention also provides the preparation method for preparing the aforementioned medical adhesive, and at the same time, the aforementioned medical adhesive is applied for the wound.
