  • Patent number: 12648969
    Abstract: A method of preparing sterile human placental allografts by providing a human placental tissue from a donor within 24 hours to 72 hours post-childbirth; removing any visible blood, blood clots, and/or blood components from the human placental tissue without scraping or scrubbing the human placental tissue to preserve structural integrity of the human placental tissue; washing the human placental tissue in an isotonic solution while maintaining the structural integrity of the human placental tissue; dehydrating the human placental tissue thereby forming the dehydrated human placental tissue; resizing the dehydrated human placental tissue into dehydrated human placental tissue portions having predetermined sizes; and sterilizing the dehydrated human placental tissue portions of step (e) thereby forming the sterile human placental allograft. Also disclosed is a sterile human placental allograft produced by the method.

  • Patent number: 12478647
    Abstract: A sterile micronized composition prepared from intact human placental tissue that is configured for wound healing. The sterile micronized composition includes micronized human amnion; micronized human chorion; and micronized human intermediate spongy layer. In certain aspects, the composition is prepared from intact placental tissue comprising a human amnion layer, human chorion layer, and an intact human intermediate spongy layer positioned between the human amnion layer and human chorion layer such that immediately before micronization the human amnion layer and the human chorion layer are not separated from one another.
