  • Publication number: 20230389911
    Abstract: The invention provides an applicator of a spongeous collagen membrane and a kit comprising such applicator and such membrane. The applicator comprises an applicator body having a guide extending in a direction from the proximal end to the distal end of the applicator body and a sliding element slidably comprising a shaft portion movable along the guide. The sliding element is provided at its distal end with a contact portion for contacting the spongeous collagen membrane, and the contact portion of the sliding element comprises mechanical fixation means configured to releasably hold the spongeous collagen membrane without substantially generating forces acting in the distal direction on the spongeous collagen membrane over its area extension. The distal end of the applicator body comprises a release surface configured to apply a release force to the spongeous collagen membrane releasing it from the mechanical fixation means for application to the wound site.

  • Patent number: 11786637
    Abstract: Methods and compositions for preparing and priming a tissue graft for an accelerated therapeutic effect are provided herein. In one embodiment, the method includes obtaining a tissue containing viable cells from a donor, wherein the viable cells are endogenous to the tissue and remain resident in the tissue; and priming the viable cells with one or more stimuli comprising simulated hypoxia to produce a primed tissue, wherein when grafted to a recipient the primed tissue provides a benefit compared to non-primed tissue.

  • Patent number: 11571494
    Abstract: A method, material, and kit for promoting neutrophils and monocytes to localize at a chronic ulcer site, promoting formation of a multi-layered cell structure in the ulcer site, promoting conversion of monocytes to macrophages, promoting secretion of the patient's own growth factors, promoting tissue proliferation and cell migration, promoting production and cross-linking of collagen at the chronic ulcer site, promoting growth of endothelial cells, promoting angiogenesis that was stalled at the chronic ulcer site, promoting formation of a vascular network and granulation, promoting oxygenation of the chronic ulcer site, and reducing one or more of purulent drainage, erythema, pain, warming, tenderness, induration, and bleeding at the chronic ulcer site.
