DECELLULARISED CELL WALL STRUCTURES FROM FUNGUS AND USE THEREOF AS SCAFFOLD MATERIALS
Provided herein are scaffold biomaterials comprising a decellularised fungal tissue from which cellular materials and nucleic acids of the tissue are removed, the decellularised fungal tissue comprising a cellulose- or chitin-based 3-dimensional porous structure. Methods for preparing such scaffold biomaterials, as well as uses thereof as an implantable scaffold for supporting animal cell growth, for promoting tissue regeneration, for promoting angiogenesis, for a tissue replacement procedure, and/or as a structural implant for cosmetic surgery are also provided. Therapeutic treatment and/or cosmetic methods employing such scaffolds are additionally described.
Methods of preparing and delivering a dry bioprosthetic valved conduit
A valved conduit including a bioprosthetic valve, such as a heart valve, and a tubular conduit sealed with a bioresorbable material. The bioprosthetic heart valve includes prosthetic tissue that has been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve. The bioprosthetic heart valve may have separate bovine pericardial leaflets or a whole porcine valve. The sealed conduit includes a tubular matrix impregnated with a bioresorbable medium such as gelatin or collagen. The valved conduit is stored dry in packaging in which a desiccant pouch is supplied having a capacity for absorbing moisture within the packaging limited to avoid drying the bioprosthetic tissue out beyond a point where its ability to function in the bioprosthetic heart valve is compromised. The heart valve may be sewn within the sealed conduit or coupled thereto with a snap-fit connection.
Methods for stabilizing collagen-containing tissue products against enzymatic degradation
Methods for producing crosslinked tissue matrices, crosslinked tissue matrices produced by such methods, as well as tissue products comprising such tissue matrices are disclosed. The methods comprise (1) dehydrating a collagen-containing tissue matrix to form a dehydrated collagen-containing tissue matrix; and (2) irradiating the dehydrated collagen-containing tissue matrix such that at least a portion of the dehydrated collagen-containing tissue matrix is crosslinked.
Antimicrobial composition for inhibiting microbial organisms in allograft and the method thereof
The present invention is a method for producing allograft tissue by applying an antimicrobial solution to allograft tissue. The antimicrobial solution exhibits antimicrobial activity to make allograft resistant to microbial organisms, such as bacterium.
DECELLULARIZED AND DEMINERALIZED BONE MATRICES AND METHODS FOR MAKING SAME
A method of making a bone matrix includes exposing a bone tissue to a solution including a surfactant and a protease; treating the bone tissue with an acid solution following exposing the bone tissue; and electrophoretically treating the acid treated bone tissue. A bone matrix has a DNA content of not greater than 0.1 micrograms per milligram sample and a modulus in a range of 180 kPa to 250 kPa.
Translucent, Dehydrated Placental Tissue and Methods of Producing and Using the Same
Compositions comprising translucent, dehydrated placental tissue and methods of preparing and using those tissues are provided. Repeated dehydration techniques may produce translucent, dehydrated placental tissues, including translucent, dehydrated placental membrane and umbilical cord, with improved visualization and/or handling characteristics. The present invention also includes methods of healing a wound of the skin, eye, nerve, tendon, muscle, dental region, or dura, including burns, comprising applying the translucent, dehydrated placental tissues of the invention to the wound.
BIOMATERIAL IMPLANTS AND METHODS OF MAKING THE SAME
Biomaterials, implants made therefrom, methods of making the biomaterial and implants, methods of promoting bone or wound healing in a mammal by administering the biomaterial or implant to the mammal, and kits that include such biomaterials, implants, or components thereof. The biomaterials may include demineralized cortical fibers, which help to promote bone repair.
SELF-ASSEMBLING GRAPHENE OXIDE-PROTEIN MATRIX
The present invention relates to a stable self-assembling graphene oxide-protein matrix comprising a disordered protein (DP) and graphene oxide (GO), wherein the DP has an opposite charge to the GO, further wherein the graphene oxide-protein matrix is in the form of a 3D structure having a lumen defined by a membrane having an inner and outer surface. The invention further relates to methods and kits for preparing such a graphene oxide-protein matrix and its uses.
Apparatus for producing strips of bone fibre, and a method of using such apparatus
Apparatus for producing strips of bone fibre comprising a vice for securing a section of rigid bone with which said apparatus is used, said vice defining a containment area and having a compression axis with which a longitudinal axis of said bone is substantially aligned in use, an arm for reciprocal linear movement along a movement axis between a rearward position and a forward position, said movement axis being parallel with said compression axis and spaced therefrom in a lateral plane, a first drive mechanism for moving said arm along said movement axis in a reciprocal manner, and a cutting head comprising a first row of cutting teeth, which cutting head is mounted to a first end of said arm with said first row of cutting teeth coincident with said containment area and disecting said lateral plane, and a method of producing a DBM fibres product using such apparatus.
REACTIVE POLYSACCHARIDE-BASED HEMOSTATIC AGENT
Compositions and methods related to powdered hemostats that crosslink during and/or after application to a bleeding site are generally described.
