  • Publication number: 20190076577
    Abstract: Provided in this disclosure are various composite grafts having a trabecular synthetic scaffold with voids defined in at least a portion of the scaffold and a biological component positioned in at least some of the voids of the scaffold. The grafts may be osteogenic, chondrogenic, osteochondrogenic, or vulnerary in nature. Also provided are methods of using the composite grafts to treat a tissue defect in a subject. Methods of manufacturing are also provided. Grafts are manufactured by additive manufacturing. Agitation may be used to combine composite grafts with additional biological component.

  • Patent number: 8586345
    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.

  • Patent number: 5833642
    Abstract: A product suitable for absorbing wound exudate comprising a series of interconnected square or rectangular perforated bags made of a substance of maximum thickness 1 mm e.g. film, which is substantially non-adherent to a wound, wherein alginic acid or a salt thereof such as calcium alginate is housed in the bags, preferably in the form of small spheres. The film preferably comprises ethylene/methyl acrylate copolymer. Alternatively, the product comprises a string along which beads of alginic acid or alginate are threaded.

  • Patent number: 5758835
    Abstract: A magnetic tape apparatus includes a head which reproduces data from or records data onto a magnetic tape, taken out from a cassette, when the tape is running. A supply reel shaft rotates a supply reel to supply the tape from the cassette to the head. A take-up reel shaft rotates a take-up reel to wind the tape from the head around the take-up reel. A back tension applying mechanism has a brake part which presses the supply reel shaft to produce a braking force on the supply reel shaft, the back tension applying mechanism applying a back tension to the tape when the braking force is produced. A pressing force varying mechanism controls a pressing force of the brake part on the supply reel shaft such that the pressing force is maintained at an appropriate level for a type of cassette.
