  • Patent number: 10973692
    Abstract: A viscoelastic wound closure dressing. The dressing can include a viscoelastic backing having a first major surface configured to face skin when in use, a first end, a second end, and a middle section located between the first end and the second end. The wound closure dressing can further include a skin-contact adhesive on the first major surface of the viscoelastic backing adjacent the first end and the second end. A majority of the first major surface of the middle section can be free of the skin-contact adhesive. The viscoelastic backing can recover, at room temperature: (i) no more than 40% of its deformation after 10 seconds, after being strained to 50% elongation for 30 minutes, and (ii) at least 70% of its deformation after 48 hours, after being strained to 50% elongation for 30 minutes.

  • Patent number: 10137222
    Abstract: A method of forming a fibrin hydrogel composition is described. The method comprises forming an aqueous solution comprising fibrinogen, fibrin-forming enzyme, and a fibrin hydrogel forming salt. The fibrin hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrin hydrogel. The method further comprises reducing the salt concentration below the threshold concentration to form a fibrin hydrogel. In some embodiments, the aqueous solution further comprises a plasticizer. A fibrin composition is also described comprising a fibrin hydrogel having a fibrin concentration ranging from 0.1 to 10 wt-%; and a fibrin hydrogel forming salt. The fibrin hydrogel forming salt has a concentration less than a threshold concentration to form the fibrin hydrogel. The fibrin hydrogel or dehydrated fibrin hydrogel can be in various physical forms such a sheet, foam, or plurality of pieces.

  • Publication number: 20180303873
    Abstract: Compositions for treating a biofilm comprising viable microorganisms are provided. The compositions include a suspending medium, a bioactive glass comprising B2O3, and an effective amount of an antimicrobial compound selected from the group consisting of antimicrobial biguanide, quaternary ammonium compound, silver or copper deposited as a coating on the surface of the bioactive glass, and antimicrobial lipid component. Methods of treating a biofilm or a surface with the compositions are also provided.
