Synthetic chord devices and methods for using the same for connecting tissues are provided. Message generating section 102 generates a Binding Update message, which contains a global address which is uniquely assigned to network element apparatus 100, the above temporarily assigned global address, and a global address of the router AR1, to transmit the generated message via the access section 101 to router AR2, which is a serving router after move. The ion-depleted pyrolysis oil stream is partially hydrotreated to reduce the oxygen content thereof, thereby producing a partially hydrotreated pyrolysis oil stream having a residual oxygen content that is less than the original oxygen content. The method further includes removing the sacrificial layer formed on the piezoelectric layer; and patterning the piezoelectric film. The first coupling pin is inserted through the first mounting hole and coupled to the coupling portion, and the second coupling pin is inserted through the second mounting hole and coupled to the first coupling hole.
