Protein biomaterial and biocoacervate vessel graft systems and methods of making and using thereof
The present invention relates to protein biocoacervates and biomaterials vessel graft systems used in cardiovascular applications and other medical applications, the components utilized in the vessel graft systems and the methods of making and using such systems. More specifically the present invention relates to protein biocoacervates and biomaterials vessel graft systems used in various medical applications and/or the devices used in such vessel graft systems including, but not limited to, vessel grafts as drug delivery devices for the controlled release of pharmacologically active agents, tubular grafts, vascular grafts, protein biomaterial sutures and biomeshes, protein biomaterial adhesives and glues, and other biocompatible biocoacervate or biomaterial devices used in the vessel graft systems of the present invention.
Method and apparatus to control the heterogeneous flow of bone cement and improve osseointegration of cemented implant
The present invention provides processes for combined applications of making grooves on an implant surface, applying MgO nanoparticles with PMMA cement, restricting the cement movement by PCL nanofiber and tethering biomolecules with PCL nanofiber to enhance mechanical stability and osseointegration of PMMA cement with bone. This is achieved through enhanced osteoconductive properties, roughness, and less viable fracture originating sites at the bone-cement interface. Such combined applications of nanoparticle and nanofiber on the mechanical stability and osseointegration of cemented implant is heretofore unknown, but as provided by the present invention can solve the debonding problem of cemented implant from bone.
RECOMBINANT SOLUBLE HUMAN TISSUE FACTOR, METHOD OF ITS PRODUCTION AND USES THEREOF
The present invention relates to a novel recombinant soluble human Tissue Factor(RshTF), which is an extrinsic hemostasis factor, produced in human HEK-cells. The present invention also relates to a hitherto unknown method of producing the RshTF as well as specific uses of RshTF and protein compositions comprising RshTF.
POLYPEPTIDE COMPOSITIONS AND METHODS OF USING THE SAME
Disclosed herein are polypeptides comprising an amino acid sequence of {[VPGVG].sub.4IPGVG}.sub.n, wherein n is an integer greater than 1. The polypeptides can be crosslinked to from biocompatible hydrogels with tunable and desirable mechanical properties. The polypeptides and hydrogels can be used in a variety of biomedical applications including treatment of bleeding, treatment of soft tissue injury, injectable filler, and tissue adhesives.
SPONGE-LIKE SCAFFOLD FOR PROMOTING HAEMOSTASIS
The present invention has discovered that a sponge-like scaffold comprising soy protein, chitin and a plasticizer has ideal physiochemical and mechanical properties for use as a haemostasis promoter. Therefore, the present invention provides the use of said scaffold for the use in promoting haemostasis in wounds, preferably haemorrhages such as nasal haemorrhage, as well as products which comprise said scaffold for use in promoting haemostasis.
Polypeptides and medical uses thereof
The present invention provides polypeptides comprising or consisting of an amino acid sequence derived from collagen type VI or a fragment, variant, fusion or derivative thereof, or a fusion of said fragment, variant of derivative thereof, wherein the polypeptide, fragment, variant, fusion or derivative is capable of killing or attenuating the growth of microorganisms. Related aspects of the invention provide corresponding isolated nucleic acid molecules, vectors and host cells for making the same. Additionally provided are pharmaceutical compositions comprising a polypeptide of the invention, as well as methods of use of the same in the treatment and/or prevention of microbial infections and in wound care. Also provided are a method of killing microorganisms in vitro and a medical device associated with the pharmaceutical composition.
Kits, formulations and solutions having enzymatically- permissive amounts of visualization agents and uses thereof
The invention relates to a proteolytic enzyme which is capable of forming fibrin when it reacts with fibrinogen, a fibrin-glue kit and a fibrin-glue formulation comprising an enzymatically-permissive concentration of a visualization agent and to their use in methods for prevention and/or reduction of adhesions and/or methods for promotion of blood coagulation sealing or filling body surfaces.
Chromatographic process for producing high purity fibrinogen and thrombin
The present invention relates to a chromatographic process for obtaining purified fibrinogen and thrombin from human plasma. The purified fibrinogen and thrombin preparations contain plasminogen in amounts less than 1 ug/mL. The low levels of plasminogen eliminates use of a proteolytic inhibitor, such as aprotinin in fibrin sealant kits which are used for human therapeutic applications.
SEALANT FORMULATIONS AND USES THEREOF
The invention relates to a storage-stable aqueous sealant formulation comprising a blood derived fibrinogen concentrate, a divalent cation and factor XIa.
Haemostatic composition comprising crystalline polyphosphate
The present invention relates to the use of polyphosphate in crystalline form for treatment of wounds, especially bleeding wounds, wherein the anion of the polyphosphate has a (numerical) average of at least 4 phosphorus atoms per polyphosphate anion. The invention additionally relates to a composition suitable for treatment of wounds, especially bleeding wounds, comprising an inventive polyphosphate and a carrier material. The invention further provides a method suitable for production of the inventive composition, which comprises the introduction of the polyphosphate and optionally further haemostatic agents into the carrier material, or into a component or into a precursor of the carrier material.
