    Abstract: The present application is drawn to a synthetic, polymer hydrogel-based material, which is able to actively induce the body's natural hemostatic coagulation process in blood or acellular plasma. The present invention provides the development of a primary amine containing polymer hydrogel capable of inducing blood coagulation and delivering therapeutics for hemostatic or wound care applications, and a method of forming such a primary amine containing polymer hydrogel capable of inducing the blood coagulation process. The primary amine containing polymer hydrogel is able to achieve the same end result as biological-based hemostatics, without the innate risk of disease transmission or immunological response, and at a fraction of the price. Furthermore, due to its inherent hydrogel-based design the material has the capability of arresting blood loss while simultaneously delivering therapeutics in a controlled manner, potentially revolutionizing the way in which wounds are treated.

  • Patent number: 8637726
    Abstract: A dressing for covering a wound in which the dressing includes: a first component having a first shape with a first dimension; a second component releasably attached to a first surface of the first component to maintain the first component in a second shape different from the first shape, the second shape having a second dimension longer than the first dimension; and an adhesive disposed on a surface of the first component different from the first surface for attaching the first component to the wound such that the second component can be released from the first component to allow the first component to take the first shape to apply a pressure to portions of the skin surrounding the wound to close the wound.

  • Publication number: 20130344130
    Abstract: A smart antimicrobial material and dressing to inhibit microbial growth is provided. Endogenous chemicals, such as metabolites produced from bacteria are utilized as chemical substrates and converted by enzymes to produce a disinfecting compound that will in turn inhibit the targeted microorganism. The material shall remain passive until such time as it encounters a microbe which expresses and/or secretes specific metabolites or markers. The enzyme or enzymes embedded in the smart material converts the metabolite into a disinfecting compound, which in turn either kills the microorganism or prevents it from multiplying on the surface of the material.

  • Patent number: 8609132
    Abstract: A flow directing material includes a substrate. The substrate includes a first region that exudes fluid under a compressive or tensile load and a second region that imbibes fluid under the compressive or tensile load. The first region has a first porosity and a first permeability and the second region has a second porosity and a second permeability. The first permeability and the second permeability are about 10?13 m2 to 105 m2. The first porosity and the second porosity are about 0.3 to about 0.7. The first porosity and the second porosity are at least about 5% different.
