  • Publication number: 20040116032
    Abstract: A matrix of collagen is obtained through the method of electroprocessing. As a common natural polymer, collagen may be electroprocessed to form a matrix for multiple different applications.. The flexibility and variability of the processing allows the collagen matrix to be predesigned to meet many applications. These applications are included, but not limited to, biomedical applications, manufactured leather applications, food casing products, and footwear and clothing products.

  • Publication number: 20040058887
    Abstract: The invention is directed to novel compositions comprising an electroprocessed material and a substance, their formation and use. The electroprocessed material can, for example, be one or more natural materials, one or more synthetic materials, or a combination thereof. The substance can be one or more therapeutic or cosmetic substances or other compounds, molecules, cells, vesicles. The compositions can be used in substance delivery, including drug delivery within an organism by, for example, releasing substances or containing cells that release substances. The compositions can be used for other purposes, such as prostheses or similar implants.

  • Publication number: 20040037813
    Abstract: The invention is directed to formation and use of electroprocessed collagen, including use as an extracellular matrix and, together with cells, its use in forming engineered tissue. The engineered tissue can include the synthetic manufacture of specific organs or tissues which may be implanted into a recipient. The electroprocessed collagen may also be combined with other molecules in order to deliver substances to the site of application or implantation of the electroprocessed collagen. The collagen or collagen/cell suspension is electrodeposited onto a substrate to form tissues and organs.

  • Publication number: 20040009600
    Abstract: A muscle implant includes an extracellular matrix, tendon and muscle cells. The extracellular matrix is made of a matrix of electroaerosol polymer droplets. Cardiac and smooth muscles may be formed by depositing an extracellular matrix onto a mandrel, the extracellular matrix comprising a polymer helically wound around the mandrel at predetermined pitches.

  • Publication number: 20030207638
    Abstract: Electroprocessed polymers are used to form specifically-shaped shoes, clothing or other related garments. A mandrel having a preselected shape is used as the target in the electroprocessing step. The resulting product has a polymer matrix of exactly the shape of the mandrel. In practice, a person's foot or other body part is used to create the predetermined shape.

  • Patent number: 6592623
    Abstract: A muscle implant includes an extracellular matrix, tendon and muscle cells. The extracellular matrix is made of a matrix of electrospun polymer fibers. The tendon is made of extruded collagen fibers and the muscle cells are disposed on the extracellular matrix in such a manner that the combination of components will functionally and structurally act as normal muscle tissue. Cardiac and smooth muscles may be similarly formed without tendons but including the extracellular matrix and muscle cells.

  • Patent number: 6010573
    Abstract: An apparatus for modifying an intravascular stent with endothelial cells and/or engineered endothelial cells which may have genetically altered DNA to minimize failure rates includes an external conductor sleeve, an insulating tube held therein, and a pair of insulated end caps, each detachably securable over each end of said insulating tube. Each insulated cap has a substantially centered aperture therethrough and a stent holder extending transversely therefrom to hold opposite ends of the stent therebetween. The insulated end caps and the insulating tube hold a solution containing the endothelial cells inside the insulating tube to surround exposed surfaces of the stent. An insulated internal conductor is received through the apertures.

  • Patent number: 5723324
    Abstract: An apparatus and method are provided for in vitro seeding endothelial cells and transfecting DNA on the luminal wall of a vascular prosthesis. The apparatus has an internal conductor and an external conductor, and a support means which maintains a suspension containing at least one of endothelial cells and DNA plasmids in contact with the luminal wall and which maintains the luminal wall between the internal and external conductors while alteration of an electrical charge transfers at least one of endothelial cells and DNA plasmids from the suspension to the luminal wall. The internal conductor is an insulated wire and the external conductor has a bore through which the internal conductor passes. A vascular prosthesis containing a suspension of endothelial cells and/or DNA plasmids sealed within its lumen fits within the bore of the external conductor and the internal conductor wire passes through the lumen.

  • Patent number: 5714359
    Abstract: An apparatus and method are provided for in vitro seeding of endothelial cells onto a surface such as a luminal wall of a vascular prosthesis. The apparatus contains an internal conductor and an external conductor, and a support means which maintains a suspension of endothelial cells in contact with the surface and which maintains the surface between the internal and external conductors while altering the charge on the surface. The internal conductor is an insulated wire and the external conductor has a bore through which the internal conductor passes. A vascular prosthesis containing a suspension of endothelial cells sealed within its lumen fits within the bore of the external conductor and the internal conductor wire passes through the lumen. While the prosthesis is rotated, an electrical potential is applied between the internal and external conductors altering the surface charge of the luminal wall of the prosthesis to facilitate adhesion of endothelial cells to the luminal wall.
