  • Patent number: 11020253
    Abstract: The present invention relates to a multi-hole stent for digestive organs, the multi-hole stent including: a body configured to form a plurality of cells through the intersection of wires and to be provided in a hollow cylindrical shape; and a film configured to be installed in contact with the inner surface of the body; wherein one or more discharge holes are formed in the film. The multi-hole stent for digestive organs is placed in a stenotic region in a biliary track, and can thus secure a discharge path by restoring a narrowed diameter. Furthermore, the film is installed on the inner surface of the body, and can thus prevent the entry of a lesion into the stent and re-stenosis attributable to the growth of the lesion and can thus provide discharge paths for body fluids generated from side branches through the discharge holes formed in the film.

  • Publication number: 20070202835
    Abstract: Disclosed is a power saving method for a wireless communication apparatus that operates in a sleep mode during a predetermined duration by exchanging Media Access Control (MAC) messages with a base station in order to reduce power consumption when there is no transmission/reception data. According to the power saving method, switching is made between the sleep mode and a normal mode by transmission data generated by an upper layer. In the power saving method, an active mode switching is performed by recognizing the start and end of data transmission/reception in the upper layer, thereby preventing unnecessary power consumption caused by a listening interval of a fixed length.
