  • Patent number: 12171888
    Abstract: The invention generally relates to dextran fibers which are preferably electrospun and devices formed from such fibers. In particular, such devices may include substances of interest (such as therapeutic substances) associated with the electrospun fibers. Upon exposure to a liquid the electrospun fibers dissolve immediately and the substances of interest are released into the liquid. Exemplary devices include bandages formed from electrospun dextran fibers and associated agents that promote hemostasis, such as thrombin and fibrinogen.
    Type: Grant
    Filed: December 1, 2021
    Date of Patent: December 24, 2024
    Assignees: Virginia Commonwealth University, The Henry M. Jackson Foundation for the Advancement of Military Medicine, Inc.

  • Patent number: 9572909
    Abstract: Nerve guides which are formed from three dimensional (3D) arrays of highly aligned electrospun fibers are provided. The electrospun fibers are oriented parallel to the long axis of the guide, and gaps and elongated spaces between the stacked fiber arrays provide channels for directed axonal growth. In some embodiments, the nerve guides also comprise high precision gradients of beneficial substances such as growth factors, which aid in nerve regeneration and growth along the guide.

  • Publication number: 20130310779
    Abstract: High-pressure bleeding wounds (and other bleeding wounds) may be treated by applying direct pressure directly in the bleeding wound, such as by applying a back pressure in a confined space around and in the wound. Certain substances and articles may be inserted into the wound, and the wound may be enclosed with that substance or article (such as a hemostatic substance, which may be polymeric), by swelling on contact with molecules (such as water molecules in the blood) encountered in the wound, generates the desired pressure to stop or at least reduce the bleeding without the detrimental effects of a tourniquet. Clot-inducing substances may be introduced into the wound contemporaneously with direct pressure application directly in the wound. Compressible and non-compressible wounds are treated. Treatment stops bleeding without producing pressure injury or ischemic damage. Medical devices using this technology are provided, including removable, biodegradable, medic-administrable devices.

  • Publication number: 20080038352
    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: 20050192622
    Abstract: An electroprocessed matrix of polymer, and specifically an electrospun matrix of fibers is attached to a substrate be using electroprocessing technique variations. First the electroprocessing equipment is configured to coat a substrate with a layer of electrosprayed droplets or wet, electrospun fibers, or a mixture thereof. The equipment is then modified to form an electrospun matrix of fibers onto the coated substrate.
