Bronislava G. Belenkaya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9603970
    Abstract: A biodegradable material with shape retention ability may be prepared using a process that includes (a) dissolving a polymer that in a first solvent to obtain a first solution; (b) dissolving a poly-N-vinyl lactam (e.g., polyvinyl pyrrolidone (PVP)) in a second solvent to obtain a second solution; (c) mixing the first solution with the second solution to obtain a liquid mixture; and (d) preparing the biodegradable material using the liquid mixture in an electrospinning process. The polymer may include a copolymer of lactide and caprolactone, where the lactide preferably includes L-lactide. The first solution may be an aprotic solvent, preferably ethyl acetate.

  • Patent number: 8183427
    Abstract: A biodegradable microfiber absorbent comprises a substantially homogeneous mixture of at least one hydrophilic polymer and at least one biodegradable polymer. The absorbent can be prepared by an electro hydrodynamic spinning of a substantially homogeneous polymer mixture. Medical dressings for burns and wounds, cavity dressings, drug delivery patches, face masks, implants, drug carriers that comprises at least one microfiber electrospun from a polymer mixture are provided. The dressings can have variable water vapor penetration characteristics and variable biodegradation times.

  • Publication number: 20100125330
    Abstract: A biocompatible small-diameter vascular graft, blood vessels conduit, or cell growth stimulator carrier composition which includes a completely biodegradable, hydrophilic non-gel material that has a controllable blood absorption or other biological liquid absorption ability, a controllable fiber architecture and pore sizes, and other biologically active properties, such as cell adhesion, proliferation and spreading, haemostatic and vascular tissue growth acceleration. The material retains its contour and shape when wet, and does not exhibit any swelling.
