  • Publication number: 20240131230
    Abstract: The present invention relates to an acellular skin substitute for breast reconstruction and a preparation method therefor. In the present invention, an acellular skin substitute may be prepared through the removal of epidermal layers and an acellularization process, in which the use of a proteolytic enzyme and a surfactant is excluded. In addition, since the acellular skin substitute is cut into suitable sizes and shapes to cover a breast reconstruction implant through design software and then cut out with a CNC machine, the time for breast reconstruction surgery may be reduced, and since no dead space is formed after suturing, the incidence of seromas may be reduced. Accordingly, the side effects of surgery may be lessened.

  • Patent number: 11956781
    Abstract: A method and apparatus of accessing a channel in a wireless local area network is provided. A destination station receives a request to send (RTS) frame to allocate a network allocation vector from a source station over a first bandwidth and transmits a clear to send (CTS) frame over a second bandwidth to the source station in response to the RTS frame. The second bandwidth is dynamically determined when a first parameter has a predetermined value.
