The present disclosure provides a method for preventing blood coagulation, comprising administering an effective amount of ginsenoside compound K (CK) to a subject in need thereof. The present disclosure also provides a use of ginsenoside compound K (CK) in the manufacture of a medicament for preventing blood coagulation. The present disclosure further provides a drug-eluting percutaneous coronary intervention (PCI) device comprising a vascular implant, the surface of which is coated with a first layer comprising ginsenoside compound K (CK) and a first bioabsorbable polymer, the first bioabsorbable polymer comprising poly-L-lactic acid (PLLA) and poly(L-lactide-co-ε-caprolactone) (PLCL) in a mass ratio of 60%-80%:20%-40%.

An adhesive tissue covering may include a base membrane and a biodegradable and biocompatible adhesive configured to bond to tissue. The adhesive may be located along one or more edges of the base membrane. In some aspects, an adhesive tissue strip may include a base membrane formed of at least one of a tissue-based material or a resorbable polymer, and a biodegradable and biocompatible adhesive configured to bond to tissue. The adhesive may be located on one side of the base membrane of the adhesive tissue strip.

The present invention is directed to the pharmaceutical sector and describes methods for administering vitamin D parenterally using resorbable polymers in the form of in situ forming implants; compression-formed implants, extrusion-formed implants, and liquid preparations. For long-acting vitamin D delivery system formulations, 0.5% to 99% by weight of resorbable polymers and 0.5% to 60% of organic solvents are used. Additionally, plasticisers in the concentration range of 0.1% to 50% may be used to assist in the extrusion process. The vitamin D dosage ranges from 2,000 to 2,000,000 IU, delivering 400 to 2,000 IU daily, without an initial peak release, thus reducing the risk of hypercalciuria.

The invention relates to an electrospun hybrid scaffold for medical applications comprising at least one synthetic polymer selected from poly(caprolactone), polylactide, poly(trimethylene carbonate), poly(lactide-co-caprolactone), poly(lactide-co-trimethylene carbonate), polylactide-b-polyethylene glycol, their copolymers or mixtures thereof and collagen-like protein. The invention also relates to methods of dispersing collagen-like protein into synthetic resorbable polymers and forming compositions suitable for electrospinning.

A non-tubular material for nerve regeneration induction, which can be used for the regeneration of a damaged part in a nerve, and which comprises: (A) a crosslinked form produced by crosslinking a low-endotoxin bioabsorbable polysaccharide having a carboxyl group in the molecule with at least one crosslinkable reagent selected from a compound represented by general formula (I) and a salt thereof via covalent bonds; and (B) a bioabsorbable polymer. R1HN—(CH2)n—NHR2 (I), wherein R1 and R2 independently represent a hydrogen atom or a group represented by formula: —COCH(NH2)—(CH2)4—NH2, and n represents an integer of 2 to 18. Thus, a medical material that can induce the regeneration of a damaged part in a nerve is provided.

A method of manufacturing a bioresorbable polymeric intravascular tubular device using a 3D printer and a bioresorbable polymeric intravascular tubular device are provided. The method comprises patterning a linear micropattern design comprising different periodicities ranging from 3 μm to 32 μm and a given depth onto a surface of a steel rod; dispensing, while the steel rod is rotating, a polymer-based ink on the generated linear micropattern using a nozzle of a 3D printer; and obtaining a bioresorbable intravascular device with an inner biomimetic topography through solidification of the polymer-based ink.

A composition for the treatment of wounds includes demineralized bone fibers (DBF) derived from allogeneic or xenogenic cortical bone and / or polymeric fibers made from resorbable and / or non-resorbable polymer, and the composition may also include an oxygen-generating material and / or an oxygen carrier.

A two-dimensional material for the medical wound area treatment is disclosed. A non-woven fabric consists of resorbable polymer filaments and collagen particles which have a particle size I>80 μm and are disposed on and / or in the non-woven fabric.
