  • Patent number: 11839694
    Abstract: Compositions that include nanoscale structured materials or precursors thereof (e.g., self: assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaiminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

  • Patent number: 10137166
    Abstract: Compositions which self-assemble under physiological conditions are formulated for application to wounds. The formulations include a pharmaceutically acceptable carrier or are provided as part of a medical device or coating. The formulations may also include other therapeutic, prophylactic or diagnostic agents. The formulation can be administered for treatment of one or more disorders or conditions. For example, the formulation may be applied to repair an injury or during surgery of the lung, eye or dura, or following an epidural or spinal tap, to stop leakage of blood, interstitial fluid, or cerebrospinal fluid. The formulation may be administered to a burn or ulcer. In one embodiment, the formulation is provided as a dry or lyophilized powder. In another embodiment, the material is provided in water. In another embodiment, the material is provided in combination with an oil and forms a laminate.

  • Publication number: 20170143788
    Abstract: Compositions which self-assemble under physiological conditions are formulated for application to wounds. The formulations include a pharmaceutically acceptable carrier or are provided as part of a medical device or coating. The formulations may also include other therapeutic, prophylactic or diagnostic agents. The formulation can be administered as appropriate for treatment of one or more disorders or conditions. For example, the formulation may be applied to repair an injury or during surgery of the lung, eye or dura, or following an epidural or spinal tap, to stop leakage of blood, interstitial fluid, or cerebrospinal fluid. The formulation may be administered to a burn or ulcer. The formulation may be dispersed in a suture or adhesive for administration at the time of or as released following suturing or gluing of a wound, thereby limiting bleeding, loss of tissue fluids, or other fluids such as those produced by parenchymal tissues such as the liver, pancreas, and gastrointestinal tract.
