  • 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.

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.

  • Patent number: 8651406
    Abstract: A pepper grinder has a body, a grinding mechanism, and a drive mechanism for operating the grinding mechanism by causing relative movement between two grinding members. The drive mechanism has a lever for reciprocating pivotal movement in opposite directions to produce a driving force, a first ratchet arranged to transmit the driving force from the lever, upon pivoting of the lever in the first direction, causing relative movement between the grinding members in a third direction to grind pepper, and a second ratchet arranged to transmit the driving force from the lever, upon pivoting of the lever in the second direction, causing relative movement between the grinding members in the third direction to grind pepper. Upon reciprocating pivoting of the lever in the opposite directions, the first and second ratchets alternate in transmitting the driving force from the lever to the grinding mechanism.

  • Patent number: 7931918
    Abstract: A method of manufacture of ECM microparticles incorporating bioactive molecules for drug delivery has been developed, using a modified emulsification method or a water-in-oil-phase-separation method. The microspheres are photochemically crosslinked to control the release of the bioactive molecules for better drug delivery usage without compromising the biocompatibility of the crosslinked structures. The method uses mild fabrication conditions and simple processes, no toxic chemical crosslinking reagent, which may cause cytotoxicity and calcification after implantation, no organic solvents, which may reduce drug availability and bioactivity, and no vigorous stirring action, which may fragmentize material with poor shape and mechanical stability and thus destabilize the emulsion. The resulting microparticles or microspheres are of controlled size, controlled release, highly biocompatible, and useful for drug delivery as well as cell culture.

  • Patent number: 7468434
    Abstract: This invention provides a method for treating an eye disease in a patient comprising: providing a photosensitive prodrug that releases upon exposure to light an active ingredient to treat the eye disease; administering the prodrug in a pharmaceutically accepted vehicle to the subject, and exposing the eye of the subject to an external light source to cause the prodrug to release the active ingredient. This invention also provides a composition for the treatment of glaucoma, comprising a compound containing a lithium ion-chelated in a crown ether- or aza-crown ether-containing chromene or diazene derivative and a pharmaceutically acceptable carrier.

  • Patent number: 7393437
    Abstract: A method for producing collagen-based scaffolds with improved characteristics, which broadens the usage of collagen in tissue engineering and the products so produced are described. The method comprises reconstitution of three-dimensional collagen matrices from collagen monomer solution and crosslinking the matrix with a light source in the presence of a photosensitizing reagent. The crosslinked products can be in any shape and form and used in the dry or wet state, for applications including but not limited to tissue engineering and controlled drug delivery.
