A high swell, long-lived hydrogel sealant formed by reacting a highly oxidized polysaccharide containing aldehyde groups with a multi-arm amine is described. More specifically, there is provided a method of defining and allocating an MCID for transmitting an IP version 6 multicast packet over an IEEE 802. When the electrodes and light guide are constructed cylindrically, the hollow space remaining between the electrodes and the light guide is provided as a suction channel for sucking out tissue particles, and in various embodiment forms, including an embodiment as an illuminating endoprobe, the electric probe is connected to an operating and controlling device by which pre. The wireless interface module can establish one or more wireless links with one or more peer EIR terminals, to join a wireless network which is collectively formed by the peer EIR terminals. The system includes: an electric motor adapted to supply mechanical energy to each of the actuation devices; an electronic control unit for the electric motor; and at least one switching device interposed between the motor and the actuation devices, the switching device serving to distribute the mechanical energy supplied by the electric motor selectively to one of the actuation devices.
